Traditional Chinese Medicine (TCM) is popular around the world and encompasses many different practices with particular emphasis on herbal TCM. Using the PubMed database, a literature search was undertaken to assess the extent herbal TCM products exert rare hepatotoxicity. Analysis of reported cases revealed numerous specified herbal TCM products with potential hepatotoxicity. Among these were An Shu Ling, Bai Fang, Bai Xian Pi, Ban Tu Wan, Bo He, Bo Ye Qing Niu Dan, Bofu Tsu Sho San, Boh Gol Zhee, Cang Er Zi, Chai Hu, Chaso, Chi R Yun, Chuan Lian Zi, Ci Wu Jia, Da Chai Hu Tang, Da Huang, Du Huo, Gan Cao, Ge Gen, Ho Shou Wu, Hu Bohe You, Hu Zhang, Huang Qin, Huang Yao Zi, Hwang Geun Cho, Ji Gu Cao, Ji Ji, Ji Xue Cao, Jiguja, Jin Bu Huan, Jue Ming Zi, Kamishoyosan, Kudzu, Lei Gong Teng, Long Dan Xie Gan Tang, Lu Cha, Ma Huang, Mao Guo Tian Jie Cai, Onshido, Polygonum multiflorum, Qian Li Guang, Ren Shen, Sairei To, Shan Chi, Shen Min, Shi Can, Shi Liu Pi, Shou Wu Pian, Tian Hua Fen, White flood, Wu Bei Zi, Xi Shu, Xiao Chai Hu Tang, Yin Chen Hao, Zexie, Zhen Chu Cao, and various unclassified Chinese herbal mixtures. Causality was firmly established for a number of herbal TCM products by a positive reexposure test result, the liver specific scale of CIOMS (Council for International Organizations of Medical Sciences), or both. Otherwise, the quality of case data was mixed, especially regarding analysis of the herb ingredients because of adulteration with synthetic drugs, contamination with heavy metals, and misidentification. In addition, non-herbal TCM elements derived from Agaricus blazei, Agkistrodon, Antelope, Bombyx, Carp, Fish gallbladder, Phellinus, Scolopendra, Scorpio, and Zaocys are also known or potential hepatotoxins. For some patients, the clinical course was severe, with risks for acute liver failure, liver transplantation requirement, and lethality. In conclusion, the use of few herbal TCM products may rarely be associated with hepatotoxicity in some susceptible individuals, necessitating a stringent pretreatment evaluation of the risk/benefit ratio, based on results of multicenter, randomized, double-blind, placebo-controlled clinical trials.


Traditional Chinese medicine, Traditional Chinese herbal medicine, Herbal hepatotoxicity, Herb induced liver injury, Herbs


Traditional Chinese Medicine (TCM) is one of the oldest healing systems worldwide, originating in the ancient Chinese philosophy and dating back to more than 2,500 years.1,2 In other Asian countries, TCM became popular and is called Traditional Asian Medicine (TAM) or Traditional Oriental Medicine (TOM), and Kampo Medicine in Japan. Since these practices have been adopted in other parts of the world, technically the topic should be considered to be Traditional Chinese and other Asian Medicine. However, in Western countries, the use of the popular name TCM has remained virtually unchanged without naming each individual country engaged in Traditional Medicine originating from ancient China. The basic principles of TCM are identical or vary only little between the numerous countries. Therefore, the use of TCM as the overall term is warranted and facilitates the discussions around major TCM related issues.

TCM is not a single entity but encompasses many different practices, including herbal medicine, acupuncture, moxibustion, massage, dietary therapy, and physical exercise such as shadow boxing.1,2 TCM is a fully institutionalized part of China's health care system and is widely used within Western medicine.2 In 2006, the TCM sector included over 200 million outpatients and around seven million inpatients, accounting for 10–20% of health care in China.2 Although the exact number of people who use TCM in the United States is unknown, it was estimated in 1997 that some 10,000 practitioners served more than one million patients each year.1 Despite its popularity, there has been concern about the efficacy and safety of TCM,14 and other issues related to scattered and inappropriate randomized controlled clinical trials of TCM.2,4,5 Adverse reactions by TCM have been reported, leading to systemic and organ specific health risks2,6 including the liver.7,8 These reactions create concern and represent a particular clinical challenge because TCM products are commonly perceived as natural and thereby erroneously as safe.

Hepatotoxicity by TCM is limited to natural products, mainly herbs, from the more than 7,000 Chinese herbal medications in use.8 Herb induced liver injury (HILI) is not restricted to Chinese herbs but may be commonly observed in virtually all countries where herbs are consumed.9 At present, HILI has been documented with published case reports or case series by at least 60 different herbs and herbal mixtures, including Chinese ones. In this review, a literature search was performed for cases of herbal TCM with special reference to hepatotoxic side effects and addressed the question of how to improve collection and evaluation of case data in the future in order to facilitate causality assessment.

Literature search and identification of reports

For a selective literature search from 1990 to 2013, PubMed was searched using the terms Traditional Chinese Medicine, Traditional Asian Medicine, Traditional Oriental Medicine, Traditional Chinese Medicine liver injury, Traditional Asian Medicine liver injury, Traditional Oriental Medicine liver injury, Chinese herbal hepatotoxicity, Chinese herbal liver injury, herbal hepatotoxicity, and herb induced liver injury. From each search, the first 25 publications underwent analysis for subject matter, data quality, and overall suitability. Citations in retrieved publications were searched for other yet unidentified case reports. The search was limited primarily to English-language case reports, case series, and clinical reviews. Full lengths publications in Chinese, Japanese, or other Asian languages were not considered, but their abstracts were used occasionally if provided in English.

Individual cases

The selected publications represented reports of cases with herbal TCM induced liver injury and originated from China including Hong Kong, Taiwan, Japan, Korea, Singapore, Thailand, Australia, Italy, Spain, France, the Netherlands, the United Kingdom, Iceland, Canada, the United States, and Argentina. Outside of China, only around 500 TCM herbs are commonly used, which is a small fraction of the medicinal herbs available. In China, this number is estimated to be more than 7,0008 or around 14,000 items.10 The present analysis includes data from a relatively low number of potentially hepatotoxic TCM products, only a few dozen herbal products and single herbs. However, non-English language publications were excluded from this review, and the information here is not an exhaustive summary of all information collected to date.

In general, evaluation of cases with suspected herbal TCM induced liver injury is challenging because numerous aspects need to be considered for a valid assessment (Table 1).1115 This includes a liver specific causality assessment, preferentially with the scale of the Council for International Organizations of Medical Sciences (CIOMS), also called the Roussel Uclaf Causality Assessment Method (RUCAM).1315 Although rarely available, most valuable for the causality evaluation is the assessment of unintentional reexposures, which requires the application of strict criteria (Table 2).16,17

An Shu Ling

A 42-year old woman from the United States took three different herbal medicines for insomnia.18 The products were An Shu Ling (syn. Jin Bu Huan) as TCM, “Ignatia Amara”, and “Relaxed Wanderer”. Following a ten week treatment course, she experienced jaundice and developed acute hepatitis. A toxicology database found the synonym Jin Bu Huan listed for An Shu Ling.

L-tetrahydropalmitine was identified in chemical analysis. The analogous hepatotoxic constituent to Jin Bu Huan also contains Stephania sinica and various herbs. The two other herbal medicines contained no suspected hepatotoxins. The product lot of An Shu Ling was confiscated and a public health warning was issued. No additional cases associated with the use of this particular product were reported. Although Jin Bu Huan itself was banned from importation into the United States18 due to the known hepatotoxic risks,7,9 a shipment of An Shu Ling reportedly cleared US customs because the respective shipping invoice contained only the Chinese botanical name.18 See also Jin Bu Huan.

Ba Jiao Lian

After drinking infusions made with the TCM Ba Jiao Lian (Dysosma pleianthum) and consuming the recommended dose, five patients in Taiwan manifested abnormal liver function tests associated with nausea, vomiting, diarrhea, abdominal pain, thrombocytopenia, leucopenia, sensory ataxia, altered consciousness, and persistent peripheral tingling or numbness.19 In a recent report from Taiwan, 17 cases with poisoning by Ba Jiao Lian were published.20 Podophyllotoxin is one of the main ingredients of the Ba Jiao Lian root and is considered the toxic agent.1921 However, the increase in the aminotransferases was small, with preference for the aspartate aminotransferase (AST) over the alanine aminotransferase (ALT).19,21 The increase of AST19 could reflect either isolated damage of mitochondria around the hepatic central vein or some muscular damage21 because of the associated increase of creatine phosphokinase.19 These uncertainties do not allow for the classification of Ba Jiao Lian as a potentially hepatotoxic herb, and it is therefore not further considered within this review.

Bai Fang

A 54-year old male patient in the United States developed subtotal liver necrosis and survived following liver transplantation (LTX).22 He used Bai Fang as a herbal TCM for an unknown time and had acute hepatitis B virus (HBV) as a cofactor. Ingredients of Bai Fang include Angelica sinensis, Cyperus rotundus, Ginseng, Ligusticum wallichii, Paeonia alba, and Rehmannia glutinosa. The possible hepatotoxic herb and its suspected ingredient remain unknown, and the causality for Bai Fang is questionable because of the concomitant acute hepatitis B. No other cases were reported.

Bai Xian Pi

In four Korean patients, the use of the herb TCM Bai Xian Pi (Dictamnus dasycarpus) was hepatotoxic, when applied as a single herb.23 Similarly, it was hepatotoxic in three patients from the United Kingdom when it was coadministered with other herbs.2426 Overall, fourteen patients from Korea developed acute toxic hepatitis due to Dictamnus dasycarpus,27 and two other Korean patients required a liver transplant due to acute liver failure.28 See also Chinese herbal mixtures.

Ban Tu Wan

A middle-aged Asian female patient living in the United States acquired fulminant hepatic failure secondary to the use of the TCM Ban Tu Wan.29 Its ingredients were Angelica sinensis, Chaenomeles, Codonopsis pilosula, Notopterygium, Polygonum multiflorum, Rehmannia, and Schisandra. The patient was evaluated for a liver transplant but did not meet transplantation requirements because of septicemia, leading to a lethal outcome.29 Other hepatotoxicity cases caused by Ban Tu Wan have not been published. See also Ho Shou Wu, Polygonum multiflorum, Shen Min, and Shou Wu Pian.

Bo He

Two men, 45-years and 46-years, from Hong Kong with a chronic HBV infection took the TCM Bo He (Mentha haplocalyx) in formulas that contained 11 elements with Bo He, shown to be hepatotoxic in the Chinese literature.30

Bofu Tsu Sho San

A 37-year old Japanese woman used the herbal TCM Bofu Tsu Sho San, a Japanese kampo medicine also called Bofu Tsu Sho San, and a diagnosis of herb induced liver injury was made.31 Bofu Tsu Sho San contains 16 herbs, Angelica, Atractylis, Cnidium, Gardenia, Ephedra, Forsythia, Glycyrrhhiza, Gypsum fibrosum, Ledebouriella, Mentha, Paeonia, Platycodon, Rheum, Schizonepeta, Scutellaria, and Zingiber, as well as Kadinum (talcum powder) and sodium sulfuricum.32 Several herbs are candidates for liver injury, including Ephedra that contains the hepatotoxic stimulant ephedrine.9,33 For Ephedra see also Ma Huang.

Boh Gol Zhee

Acute hepatitis was described after use of the TCM Boh Gol Zhee (syn. Bol Gol Zhee, Bu Gu Zhi, Bu Ku Zi, Sheng Bu Gu Zhi, Sheng Po Gu Zhi) in two patients from Korea34,35 and in three patients from Hong Kong.36 Boh Gol Zhee represents not a herbal mixture but seeds of Psoralea corylifolia, and when used at high amounts psoralens are potentially hepatotoxic.3436 Psoralens were hepatotoxic candidates in another patient who experienced severe hepatotoxicity with Indian Ayurvedic herbal products.37 These included Bakuchi tablets that contain extracts from Psoralea corylifolia leaves with psoralens for treatment of vitiligo.

Chai Hu

The risk of liver injury was increased in overall 61 Taiwanese patients with HBV infections treated with some products of TCM containing Chai Hu (Bupleurum falcatum).38 In particular, two products were involved, Xiao Chai Hu Tang with 19 patients and Long Dan Xie Gan Tang with 14 patients. In other individuals without HBV infections, various herbal TCM products containing Bupleurum may be hepatotoxic, see for instance Da Chai Hu Tang,39 Kamishoyosan,40 and a report referring to a herbal TCM mixture.25 See also Long Dan Xie Gan Tang and Xiao Chai Hu Tang.


Six Japanese patients developed hepatic injury after using Chaso, a herbal TCM that promotes weight loss.41 This product contained Camellia sinensis (Green tea, syn. Lu Cha as TCM), the hepatotoxic Cassia tora (Senna), Crataegus, Chrysanthenum morifolium Ramat., Lotus, and Lycium barbarum. As an ingredient of the Chaso formula, Camellia sinensis extract is known to facilitate weight loss. Since the toxic property of Camellia sinensis extract was unknown in 2003 when Chaso hepatotoxicity was first described, it was not considered to be the hepatotoxic agent.41 Outcome was favorable in all patients, with only one patient requiring LTX. Chemical product analysis showed lack of fenfluramine and heavy metals, such as copper, lead, bismuth, cadmium, stibium, stanum, mercury, and chromium, but N-nitroso-fenfluramine was found. N-nitroso-fenfluramine was considered a possible but not yet proven culprit,41 since similar cases of hepatotoxicity by various other slimming aids in the United Kingdom,42 Hong Kong43 and Japan44 including the TCM herbal product Onshido,41 were reported. An additional 21 cases of Chaso-induced hepatotoxicity were reported to health officials in Japan and not further analyzed.41 A cautionary statement by the authors recommended further toxicological analyses to determine possible hepatotoxicity by N-nitroso-fenfluramine, which was not established toxicologically or clinically until 2003.41 Toxicological evidence of its hepatotoxic property was not provided since 2003, and clinical evidence cannot be expected because it was removed from the market in 1997. The popular and widely used slimming aid fenfluramine was withdrawn from clinical use because of cardiac rather than hepatic complications, which remain unknown.41 Consequently, there is little toxicological and clinical evidence available regarding the hepatotoxicity of fenfluramine or N-nitroso-fenfluramine. For more details and discussions see Lu Cha (Camellia sinensis) and Onshido.

Chi R Yun

Taiwanese patients who used the TCM Chi R Yun (Breynia officinalis) experienced hepatotoxicity.4547 There was intentional and unintentional Chi R Yun overdose in two patients45 and acute poisonings in 19 patients.46,47 Because of their similarities, Breynia officinalis was mistaken for another plant, the TCM Yi Yi Qui (Securinega suffruticosa).46,47

Chinese herbal mixtures

Patients of this section used an unnamed, unclassified herbal mixture of TCM. Additionally, in some of these cases, only individual herbs had been declared by name. Since the herbal mixtures have all herbs presented as ingredients, these mixtures could not be added to an existing named herbal product group.

Herbal hepatotoxicity was published for a heterogeneous group of herbal mixtures of TCM,2426,4851 primarily from the United Kingdom.2426,4850 In three cases, hepatotoxicity was described following herbal TCM use, but firm details concerning the applied herbs were missing.4850 More information was provided by other reports.2426 One treatment consisted of Dictamnus dasycarpus (syn. Bai Xian Pi), Gentiana scabra, Hedyotis diffusa, Paeonia suffructicosa, Paris polyphylla, Rehmannia glutinosa, Smilax glabra, and Sophora subprostrata.25 Another patient used Angelica sinensis, Bupleurum chinese, Dictamnus dasycarpus, Paeonia suffructiosa, Philodendron chinese, Saposhnikovia divaricata, Shisandra chinesis, Shizonepeta tenuifolia, and Tribulus terrestris.25 A third patient with a fatal clinical course used a mixture consisting of Cocculus trilobus, Dictamnus dasycarpus, Eurysolen gracilis, Glycyrrhiza, Lophatherum, Paeonia, Potentilla, and Rehmannia glutinosa.24 Considering these three cases from two reports,24,25 it is possible that either Dictamnus dasycarpus or Paeonia species could be the toxic herb.25 Four Korean patients with toxic liver injury used Dictamnus dasycarpus as a single herb.23 In addition, analysis of a herbal remedy taken by another patient with fulminant liver failure and unsuccessful LTX confirmed the presence of Dictamnus dasycarpus. These cases support an etiological role of this herb in TCM hepatoxicity.26

The herbal mixture of TCM used by a patient in Canada led to acute liver failure and successful LTX in the United States.51 This mixture consisted of twelve herbs, including Alisma plantago aquatica, Artemisia capillaris, Bupleurum, Chrysanthemum morifolium, Circuma, Gardenia jasminoidis, Gentiana scabra, Glycyrrhiza, Magnolia, Paeonia, Plantago asiatica, and Saussurea lappa. The toxic culprit remains unknown.

Chuan Lian Zi

A 45-year old male patient with chronic HBV infection from Hong Kong was treated with the TCM Chuan Lian Zi (Melia toosendan) and experienced herbal hepatotoxicity.30

Ci Wu Jia

Two Korean patients consumed the herbal TCM Ci Wu Jia (Acanthopanax senticosus), developed acute toxic hepatitis with acute liver failure, and required LTX.25

Da Chai Hu Tang

In a Japanese patient, autoimmune hepatitis was triggered by the use of the TCM Da Chai Hu Tang (syn. Dai Saiko To, TJ-8), a mixture of aqueous extracts from seven plants, Bupleurum falcatum, Ginseng, Glycyrrhiza glabra, Pinellia, Scutellaria, Zingiber officinale, and Zizyphus jujuba.39 The specific culprit remained unknown. Da Chai Hu Tang contains the same components as the potentially hepatotoxic TCM Xiao Chai Hu Tang (syn. Sho Saiko To Syo Saiko To, Syo Xiao Hu Tang, TJ-9) but in different proportions.39,52 See also Bupleurum and Xiao Chai Hu Tang.

Da Huang

A 45-year old man from Hong Kong with chronic HBV infection used the herbal TCM Da Huang (Rhubarb, Rheum palmatum) and died from acute liver and organ failure due to herbal hepatotoxicity.30

Gan Cao

A 46-year old man from Hong Kong with a chronic HBV infection took the TCM Gan Cao (syn. Glycyrrhiza uralensis, Liquorice, Gan Cao Zhi, Shen Nong Ben Cao Jing, Zhi Gan Cao) in formulas. These contained 11 elements, and Gan Cao was the likely toxic agent for the observed hepatotoxicity.30 Recovery was complete after discontinuation of Gan Cao.

Ge Gen

The two 57- and 58-years old women from Korea ingested juice of the herbal TCM Ge Gen (Pueraria lobata, syn. Arrowroot) and developed symptomatic toxic hepatitis.53 Clinical symptoms and laboratory findings rapidly improved following cessation of Ge Gen and supportive care.

Glycyrrhiza uralensis

See Gan Cao.

Ho Shou Wu

A 54-year old Korean woman consumed Polygonum multiflorum as the TCM Ho Shou Wu (syn. He Shou Wu, Shou Wu Wan, Fo Ti) and experienced toxic hepatitis.54 Hepatotoxicity in a 33-year old woman from Hong Kong with a chronic HBV infection was assumed to be due to Ho Shou Wu as well. However, other medications also included the hepatotoxic Jue Ming Zi (Cassia obtusifolia tora, Senna) and 10 additional, unidentified herbal items.30

Huang Qin

Nineteen Japanese patients developed liver injury after the use of the herbal TCM Huang Qin (Scutellaria baicalensis, syn. Chinese skullcap), which is a herbal mixture called Ogon in Kampo medicine of Japan.55 Hepatotoxicity was described in four patients from the United States who used Huang Qin in a dietary supplement which also contained black catechu (Acacia catechu), glucosamine, chondroitin, and hyaluronic acid.5658Acacia catechu was used as one of several Indian Ayurvedic herbs in a patient with severe hepatotoxicity and is thereby a possible culprit.37 However, the herbal extract of Chinese skullcap is the more likely cause of the reported hepatotoxicity.5658 There are some hundred species of skullcap (Scutellaria), including Scutellaria lateriflora, that have potential hepatotoxic risks, but often information regarding respective species was missing.9

Hwang Geun Cho

A 37-year old Korean male patient consumed the herbal TCM Hwang Geun Cho (Corydalis speciosa) and was diagnosed with acute herbal hepatotoxicity.59 Symptoms disappeared and laboratory values gradually returned to near normal values following cessation and supportive management.

Ji Gu Cao

A 38-year old man from Hong Kong with chronic hepatitis B took the herbal TCM Ji Guo Cao (syn. Abrus cantoniensis, Ji Gu Cao Wan) and was diagnosed with herb induced liver injury, possibly caused by contaminated hepatotoxic seeds.30

Ji Xue Cao

Three women aged 61, 52, and 49 years from Argentina ingested the herbal TCM Ji Xue Cao (Centella asiatica, syn.Gotu Kola) and developed herbal hepatotoxicity by Centella asiatica.60 Outcomes were favorable after discontinuation of the medication and ursodeoxycholic acid therapy.

Jia Wei Xiao Yao San

A 3.5 year old boy from Korea consumed tea prepared from the herbal TCM Jiguja (Hovenia dulcis), resulting in the development of toxic hepatitis.61 Because acute liver failure emerged, the boy was transferred to another hospital for further evaluation and eventually LTX. In addition, two other adults from Korea developed toxic hepatitis after ingesting Hovenia dulcis,27,28,61 and one of these patients required LTX.28

Jin Bu Huan

Hepatotoxicity associated with the herbal TCM Jin Bu Huan, syn. An Shu Ling,18 was reported from Hong Kong,62 in eleven patients from the United States,18,6365 one patient from Canada,63 and one patient from Italy.66 L-tetrahydropalmitate is the active ingredient of Jin Bu Huan and the presumed causative agent for hepatotoxicity. The herbal medication usually contains only Lycopodium serratum, or rarely several unrelated herbal species, including Corydalis species, Panax ginseng, Pseudo ginseng, or two species of Stephania.18,6367

Jing Tian San Qi

Prior to 2008, there were 41 reported cases from China of hepatic sinusoidal obstruction syndrome (HSOS), formerly called hepatic veno-occlusive disease (HVOD), attributed to the herbal TCM Jing Tian San Qi (Sedum aizoon, syn. Stonecrop).68 However, causal attribution to Sedum aizoon was in retrospect incorrect. Sedum aizoon lacks pyrrolizidine alkaloids (PAs), and when administered to experimental animals, HSOS did not emerge.69 This suggested that a herb containing PAs was likely responsible for the reported cases.68 Consistent with this, in another hepatotoxicity case from Hong Kong, HSOS was initially ascribed to Sedum aizoon but was later determined to be caused by the herbal TCM Shan Chi (Gynura segetum).69 The appearance of Sedum aizoon is similar to Gynura segetum but can be differentiated by an expert eye.69 Comparative studies with both herbs provided clear supportive evidence for Gynura segetum as the culprit for additional cases of HSOS over Sedum aizoon. Respective studies showed in mice that the PAs containing Gynura segetum but not the PAs lacking Sedum aizoon produced experimental HSOS as assessed by liver histology.69 In an earlier experimental study, a model of the hepatic veno-occlusive disease was established by PAs derived from a herb described erronously as Sedum aizoon,70 which again does not contain PAs.69,71,72 This suggested that the described experimental model70 was due to the action of a herb containing PAs, most likely Gynura segetum,69,7173 rather than to PAs lacking Sedum aizoon.71 Other authentication problems of Gynura segetum had to be resolved in relation to the TCM Mao Guo Tian Jie Cai (Heliotropium lasiocarpum), another herb that also contains PAs.7476 HSOS cases had been initially attributed to Gynura segetum,74,75 but this causal attribution was in retrospect incorrect since Heliotropium lasiocarpum was determined as culprit.76 Overall, careful analyses finally led to a clear picture of HSOS by Gynura segetum.77,78 Taken together, there is little evidence for the hepatotoxic potential of Jing Tian San Qi. Therefore, the herbal TCM Sedum aizoon will not be further considered for hepatotoxicity.

Jue Ming Zi

A 33-year old woman from Hong Kong with a chronic HBV infection was treated with the herbal TCM Jue Ming Zi (syn. Cassia obtusifolia, Senna obtusifolia, Cao Jue Ming) and experienced liver injury.30


In one single Japanese woman, liver injury was reported following the use Kamishoyosan, a traditional Japanese herbal drug (Kampo medicine) and synonym to the TCM Jia Wei Xiao Yao San, Dan Zhi Xiao Yao San, or TJ-24.40 Kamishoyosan is a herbal mixture and contains several components, including Angelica sinensis, Atractylodes racea, Bupleurum falcatum, Gardenia, Glycyrrhiza glabra, Mentha haplocalyx, Moutan, Paeonia alba, Sclerotium Poriae Cocos, and Zingiber officinale, as described in the case report40 or as assessed by an internet search for a refined botanical description of the herbal components. Detecting the causative agents was difficult, but Scutellaria was definitively excluded.54,79 There is some uncertainty regarding the Mentha species, declared as Mentha herb in the case report40 and as mentha (pennyroyal) subsequently.79 An additional internet search to further determine the Mentha species commonly used in Kamishoyosan found Mentha haplocalyx Briq or Mentha arvensis var. piperascens Malinvaud (Japanese field mint) as the most probable component.


Six patients from Korea consumed the herbal TCM Kudzu (Pueraria thunbergiana) and were diagnozed with acute toxic hepatitis.27


See Gan Cao.

Long Dan Xie Gan Tang

Overall, fourteen Taiwanese patients with HBV infection were found to be at higher risk for hepatotoxicity when treated with the TCM Long Dan Xie Gan Tang (syn. Long Dan Xie Gan Wan).38 This herbal mixture contains Acebia, Alisma, Angelica sinensis, Bupleurum, Gardenia, Gentiana, Glycyrrhiza, Plantago, Rehmannia, and Scutellaria. A similar increase in risk was observed in another patient group treated with the TCM Xiao Chai Hu Tang, which also contains Bupleurum among other herbs. See also Bupleurum and Xiao Chai Hu Tang.

Lu Cha

Lu Cha (Camellia sinensis, green tea) is a TCM plant and one of several herbal ingredients in the two herbal mixtures Chaso and Onshido. These mixtures were marketed as weight loss aids by Chinese pharmaceutical companies and found to be hepatotoxic, as described in 2003.41 N-nitroso-fenfluramine but not green tea was discussed as the possible but unproven hepatotoxic ingredient for these herbal mixtures. However, this case series did not prove that N-nitroso-fenfluramine was the toxic agent.41 Whether Camellia sinesis may have contributed to the observed hepatotoxicity is unclear, because information on the amounts of green tea in these two products was not provided. At least as an extract, Camellia sinensis is a potent weight loss aid with potentially hepatotoxic effects, as thoroughly discussed first in 20048082 and in subsequent years.9,8388 Therefore, hepatotoxicity of green tea as extracts was not yet clearly established in 2003 when the respective case reports were published.41

Green tea is one of the most popular beverages, as are black tea and coffee. There is no question that the conventional use of these beverages including green tea does not harm the liver. In the past, however, weight loss aids were supplemented by green tea concentrated as extracts, and these carried the risk of liver injury.9,8088 According to the manufacturers, the weight loss aids Chaso and Onshido contained green tea and other herbs.41 Presumably, green tea was included as extracts to enhance weight loss, although the extract form was not specifically mentioned by the manufacturers. The producers did not mention that the synthetic adulterant N-nitroso-fenfluramine was also an ingredient in the two products. This adulterant was later identified by chemical analyses, but evidence of hepatotoxicity was not presented and evaluation by further studies was recommended.41 The most likely candidate for the liver injury was green tea, if it was supplied in the extract form. For details see also Chaso and Onshido.

Ma Huang

Six patients originating from the United States experienced acute hepatitis associated with the use of the herbal TCM Ma Huang and its ingredients of Ephedra species.9,22,33,8991 Out of these six cases, one patient also coadministered kava, one also had disulfiram, and one had a chronic HBV infection.22 Two patients developed acute liver failure,22,90 and one of them required LTX.22 In another patient from the United Kingdom, acute liver failure emerged and LTX was necessary.92 Ma Huang is also one of the ingredients of Pro-Lean®,9 a potential hepatotoxic herbal mixture.93 For Ephedra, see also Bofu Tsu Sho San.

In four patients from Hong Kong, HSOS developed following the use of the PAs containing herbal TCM Mao Guo Tian Jie Cai (Heliotropium lasiocarpum).76 It was initially mistaken as the PAs containing herbal TCM Gynura segetum.7375 Outcome was deleterious for one of the four patients.76


Six Japanese patients experienced hepatic injury due to the use of the weight loss aid Onshido, a TCM herbal mixture.41 This herbal product contained Aloe, Camellia sinensis, Crataegus, Gynostemma pentaphyllum makino, and Raphanus. Outcome was favorable in all patients except for one with a lethal clinical course. Chemical product analysis of Onshido showed lack of fenfluramine and heavy metals such as copper, lead, bismuth, cadmium, stibium, stanum, mercury, and chromium but the presence of N-nitroso-fenfluramine as a possible but ultimately unproven hepatotoxic agent. N-nitroso-fenfluramine was also considered the possible culprit in additional cases of hepatotoxicity by various other slimming aids in the United Kingdom,42 Hong Kong,43 including the TCM product Chaso in Japan.41 Additional 135 Onshido-induced cases of hepatotoxicity were reported to health officials in Japan but not further analyzed.41 The hepatotoxic properties of Camellia sinensis extracts were discovered in 2004,9 and its role in Camellia sinensis induced hepatotoxicity was not evaluated in 2003.41 For additional details and discussions see also Chaso and Lu Cha (Camellia sinensis).

Polygonum multiflorum

Polygonum multiflorum is a member of the family Polygonaceae, genus Fallopia. Either alone or in combination with other herbs and vitamins, it is a constituent of various potentially hepatotoxic herbal TCM products.2830,54,9498 Among these are Ban Tu Wan,29 Ho Wu Shou,30,54 Shen Min,95 and Shou Wu Pian.96103 Occasionally, Polygonum multiflorum containing herbal TCM products such as Ho Shou Wu, Shen Min, Shou Wu Pian, and Zhi Shou Wu are considered interchangeable terms.94 However, ingredients may vary from product to product, requiring specific and qualifying product names. The mechanism of hepatotoxicity of Polygonum multiflorum is not known and disputed,9496,99101 although the injury is usually attributed to the anthraquinones such as chrysophanol, emodin, and rhein, which are major constituents in Polygonum multiflorum.94 In a single report, however, the major compound identified in the recovered tablets was a stilbene glycoside, tetrahydroxystilbene-glucopyranoside.94,96 LTX was necessary in three patients from Korea after using Polygonum multiflorum.28 For details see Ban Tu Wan, Chinese herbal mixtures, Ho Wu Shou, Shen Min and Shou Wu Pian.

Rhen Shen

Six patients originating from Korea used the herbal TCM Rhen Shen (Panax ginseng, Ren Seng) and developed acute toxic hepatitis.27

Sairei To

Two Japanese men consumed the kampo medicine Sarei To (syn. Chai Ling Tang), which is a blend of two TCMs, Xiao Chai Hu Tang and Wu Ling San Wan, and experienced herbal hepatotoxicity.104,105 Among the Sairei To ingredients are Alisma, Atractylis, Bupleurum, Cinnamomum, Ginseng, Glycyrrhiza, Pinellia, Polyporus, Poria, Scutellaria, Zingiber, and Zizyphus. Several possible culprits are under consideration, including Pinellia ternate,104 and other components of Sairei To.105

Shan Chi

In two Chinese women, 51 and 39 years old, HSOS emerged, which was induced by PAs of the herbal TCM Shan Chi Gynura segetum (syn. Ju San Qi, Ju Shan Qi, Ju Ye San Qi, San Qi Cao).73 One of these two patients required a LTX. Other cases of HSOS by Gynura segetum were reported from China,59,60,77,78 with a lethal outcome in one patient.59 In a 54-year old woman with HSOS from Hong Kong, PAs derived from Gynura segetum rather than the herbal TCM Jing Tian San Qi (Sedum aizoon) devoid of PAs were the likely hepatotoxic agents.69

Additional six cases were earlier suspected,74,75 but in at least four cases the culprit was the PAs containing herb Heliotropium lasiocarpum rather than Gynura segetum.76 An additional four patients experienced HSOS by Gynura segetum, one with a lethal course.71 Correspondingly, at least 52 HSOS cases have been attributed to Gynura segetum until 2011,69 and 116 cases until 2012.71

The clinical features have now been clearly described, establishing Gynura segetum but not Jing Tian San Qi (Sedum aizoon) as the cause of HSOS.69,71,72 The diagnosis was ascertained in a 54-year old female patient with HSOS by thorough investigations of the patient herself and by animal studies.69 Her clinical diagnosis of HSOS was firmly established by meeting the modified Seattle criteria, characterized by hyperbilirubinemia, hepatomegaly, and weight gain due to fluid accumulation. Liver histology confirmed the diagnosis of HSOS. Pyrrole-protein adducts as biomarkers and pyrrole-GSH conjugates detected in her blood using the new method ultra performance liquid chromatography-mass spectrometry

(UPLC-MS) analysis. Since the ingested herb was unknown, the cultivated herb from the patient's home was collected and authenticated as the TCM herb Gynura segetum. Together with the authenticated TCM herb Sedum aizoon cultivated and collected from another Chinese area, various comparative studies in animals were made. All of these studies confirmed that the observed HSOS arose from the consumption of PAs containing Gynura segetum, an erroneous substitute of the non PAs containing Sedum aizoon.69 The blood test of pyrrole-protein adducts using UPLC-MS analysis was employed as a biological biomarker in subsequent patients.71

Shen Min

A 28-year old woman from the United States developed acute hepatitis following the use of the herbal TCM Shen Min.95 The product label for this Shen Min product had a list of components that included plants and vitamins. Polygonum multiflorum is one of the main components of Shen Min, and the respective content was described as Shen Min 12: 1 standardized extract (Polygonum multiflorum) 450 mg per serving and as He Shou Wu powder 870 mg per serving. Polygonum multiflorum, however, was not specified here. Other declared contents of the used Shen Min product were vitamin A, vitamin B6, biotin, niacin, pantothenic acid, soy isoflavones, black cohosh, horse chestnut, hydrolyzed collagen, silica from plant sources, ginkgo biloba, uva ursi, Burdock, Cayenne pepper, and Piper nigrum. See also Ho Shou Wu, Polygonum multiflorum, and Shou Wu Pian.

Shou Wu Pian

As described in 1996, a 31-year old pregnant Chinese woman from Hong Kong developed acute hepatitis after consumption of the TCM Shou Wu Pian, with Polygonum multiflorum as the main component.99 Subsequently, similar case reports related to Shou Wu Pian followed from Australia,100 Italy,98,101 the Netherlands (a 5-year old girl),96 the United States,102 Japan,103 and Korea.97 Shou Wu Pian is a herbal mixture with a wide variability of its ingredients, and details are rarely mentioned.94,97,103 For example, according to the information via the internet, one of the numerous possible formula compositions could be: Achyranthes bidentata, Cuscuta chinensis, Eclipta prostrata, Ligustrum lucidum, Lonicera japonica, Morus alba, Polygonum multiflorum, Psoralea corylifolia, Rehmannia glutinosa, Rosa laevigata, Sesemum indicum, and Siegesbeckia orientalis. This composition varies substantially from the one of Shen Min,95 which also contains Polygonum multiflorum and is discussed above. See also Ho Shou Wu, Polygonum multiflorum, and Shen Min.

White flood

A 23-year old man from the United States experienced hepatotoxicity following use of the commercial product White flood, which contained the herbal TCM Wu Zhu Yu (Evodia rutaecarpa, club moss) and the herbal TCM Qian Ceng Ta (Huperzia serrata).106 Other ingredients included acesulfame potassium, beet root, caffein, calcium silicate, carnitine tartrate, Carno-Syn® beta-alanine, citrulline, cocoa bean, cryptoxanthin, folic acid, gamma-aminobutyric acid (GABA), glucuronolactone, selenium, L-norvaline, L-tyrosine, lutein, malic acid, ornithine, potassium gluconate, sucralose, sugar cane, vinpocetine (from Vinca plant), watermelon flavor, and zeaxanthin. After discontinuing use of the product, the outcome was favorable.

Xiao Chai Hu Tang

The treatment with the herbal TCM Xiao Chai Hu Tang (syn. Sho Saiko To, Syo Saiko To, Syo Xiao Hu Tang, TJ-9) resulted in liver injury in four Japanese patients with increased liver values prior to treatment.107 For 19 Taiwan patients with HBV infection, treatment with Xiao Chai Hu Tang was associated with an increased risk for liver injury.38 One additional patient from Taiwan had the same response to Xiao Chai Hu Tang following cholecystectomy.108 Xiao Chai Hu Tang is a mixture of several herbs, including Bupleurum falcatum, Ginseng, Glycyrrhiza glabra, Pinellia tuber, Scutellaria baicalensis, Zingiber officinale, and Zizyphus jujuba. Therefore, its composition is the same as the TCM Da Chai Hu Tang (syn. Dai Saiko To, TJ-8), but in different proportions.39,52 See also Bupleurum, Da Chai Hu Tang, and Long Dan Xie Gan Tang.

Yin Chen Hao

In seven patients from Korea, the use of the herbal TCM Yin Chen Hao (Artemisia capillaris) resulted in the development of acute toxic hepatitis.27 One additional Korean patient did require LTX.28


A 59-year old man from Hong Kong with chronic hepatitis B and associated HBeAg-positive liver cirrhosis was treated for cramps with a herbal TCM formula consisting of eleven different herbal elements, including the hepatotoxic Zexie (Alisma orientalis).30 He died from complications due to a severe course of herbal hepatotoxicity.

Zhen Chu Cao

A 37-year old man from Hong Kong with a chronic hepatitis B had been taking the TCM Zhen Chu Cao (syn. Phyllanthus urinaria) and experienced herbal hepatotoxicity due to Zhen Chu Cao.30 After cessation of the toxic herbal product, there was a full recovery.

Clinical and regulatory considerations

The present study is a very limited analysis of herbal TCM hepatotoxicity based on some hundred cases published in 91 reports. Most patients made a full recovery upon cessation of the herbal TCM product,18108 but some developed acute liver failure.24,28,29,30,41,51 In these publications, individual herbs and herbal mixtures suggested to be hepatotoxic included An Shu Ling, Bai Fang, Bai Xian Pi, Ban Tu Wan, Bo He, Bofu Tsu Sho San, Boh Gol Zhee, Chai Hu, Chaso, Chi R Yun, Chuan Lian Zi, Ci Wu Jia, Da Chai Hu Tang, Da Huang, Gan Cao, Ge Gen, Ho Shou Wu, Huang Qin, Hwang Geun Cho, Ji Gu Cao, Ji Xue Cao, Jiguja, Jin Bu Huan, Jue Ming Zi, Kamishoyosan, Kudzu, Long Dan Xie Gan Tang, Lu Cha, Ma Huang, Mao Guo Tian Jie Cai, Onshido, Polygonum multiflorum, Ren Shen, Sairei To, Shan Chi, Shen Min, Shou Wu Pian, White flood, Xiao Chai Hu Tang, Yin Chen Hao, Zexie, Zhen Chu Cao, and various unclassified Chinese herbal mixtures. The reporting physicians likely assumed for each case a clear causal association between the use of the herbal TCM product and hepatotoxicity. However, this assumption is often based merely on a temporal association and requires further rigorous evaluation.

A good approach with some limitations for the establishment of causality for a given herb or herbal mixture in hepatotoxicity is to assess reported positive reexposure test results. They are obtained through unintentional readministration, although this is commonly observed in only a few selected cases.16,17 In the past, this assessment has been done for 34 cases of suspected herbal hepatotoxicity, including 14 cases due to herbal TCM,17 applying established criteria for a positive reexposure test (Table 2). Among the now assessed 25 patients of suspected herbal hepatotoxicity of TCM with reported positive reexposure test results, criteria based evaluation confirmed a positive reexposure test result in 14 cases, whereas the results were negative in four cases or uninterpretable in seven cases (Table 3). Accordingly, positive reexposure test results were obtained for Chinese herbal mixtures (cases 2 and 3), Hwang Geun Cho (case 6), Ji Xue Cao (case 7), Jin Bu Huan (cases 9 and 10), Lu Cha (cases 13–15), Polygonum multiflorum (case 20), Shou Wu Pian (case 21), and Xiao Chai Hu Tang (cases 23–25) (Table 3), confirming the hepatotoxic risk of these products.17

The liver specific CIOMS scale for causality assessment is applicable to all cases of suspected herbal TCM hepatotoxicity.14,15,27,28,30,53,69,71,97,109,110 This scale was rarely used in the cases of the present evaluation,18108 although CIOMS data were provided for all 7, 25, and 27 TCM cases in three studies.30,97,110 In the course of causality assessment, highly probable or probable causality levels were obtained for various types of TCM formulas,30 Bai Xian Pi,27,28 Chinese herbal mixtures,17 Ci Wu Jia,28 Gan Coa,30 Ge Gen,53 Ho Shou Wu,54 Juguja,28 Ji Xue Cao,60 Jin Bu Huan,17 Kudzu,27 Ling Yang Qing Fei Keli,30 Lu Cha,82,83Polygonum multiflorum,17,30 Rhen Shen,27 Shan Chi,69,71 Shen Min,95 Syo Saiko To,17 Yin Chen Hao,27,28 and Zexie.30 Clinical assessment was partly difficult because data were often incomplete in many cases regarding indication for treatment, daily dose, quantitative composition of herbal mixtures, duration of treatment, exclusion of alternative causes, and clinical course.18108 These shortcomings are also common to cases of herb induced liver injury, which are unrelated to TCM7,12,1417,111 and to drug induced liver injury.112

Some common TCM herbs and herbal products with potential hepatotoxicity were not discussed or specifically referenced above as additional cases since they were listed without further details.62 Among these are Cang Er Zi (Xanthium sibiricum), Chuan Lian Zi (Melia toosendan), Hu Bohe You (Mentha pulegium, Pennyroyal oil), Hu Zhang (Polygonum cuspidatum), Huang Yao Zi (Dioscorea bulbifera), Ji Ji (Chloranthus serratus), Jin Bu Huan (Lycopodium serratum and other herbs), Lei Gong Teng (Tripterygium wilfordii Hook), Ma Huang (Ephedra sinica), Qian Li Guang (Senecio scandens), Shi Can (Teucrium chamaedrys, Germander), Shi Liu Pi (Pericarpium granati), Tian Hua Fen (Trichosanthes kirilowii), Wu Bei Zi (Galla chinensis), Xi Shu (Camptotheca acuminata), and Xiao Chai Hu Tang (Bupleurum falcatum, Scutellaria baicalensis, and other herbs).62 Additional lists refer to 24 cases of liver damage by Polygonum multiflorum,113 two cases of markedly elevated liver enzymes with the herbal TCM Bo Ye Qing Niu Dan (Tinospora crispa),114 and to a single case of liver injury with verified causality by the CIOMS scale attributed to the herbal TCM Du Huo (Angelica archangelica).115

Problematic for human use is the possible lack of quality control and authentication of herbal products (Table 1)12 as well as adulteration and contamination with dust, pollens, insects, rodents, parasites, microbes, fungi, mold, toxins, and pesticides.6 For herbal TCM products, specific problems have been linked to mislabeling on the package insert3,63 including the wrong herbs,46,47 insufficient sample amounts,116 adulteration with undeclared synthetic drugs,3,6,10,62 contamination by hepatotoxic seeds30 and heavy metals such as arsenic, mercury, and lead.6,116 These shortcomings are well recognized112,14,116 and require efforts by manufacturers and regulatory agencies (Table 1).117

Of additional concern is the potential hepatotoxicity of non-herbal TCM elements.10,27,28,30,62,118122 They are commonly used in connection with herbal TCM products,10,30 and even named as such.10 Known or potentially hepatotoxic non-herbal TCM elements are Bai Hua She (venom of the Chinese viper Agkistrodon acutus),30 Jiang Can (dried larvae of Bombyx Batryticatus, infected by Batrytis bassiana),30 Ling Yang Qing Fei (antelope horn),30 Liyu Danzhi (carp juice),118 Quan Xie (dry polypides of the Scorpio Buthus martensii),30 Sang Hwang (Phellinus linteus, mushroom),27,28 Song Rong (Agaricus blazei, Himematsutake as Japanese Kampo Medicine, mushroom),119 Wu Gong (dried polypites of the centipede Scolopendra subspinipes mutilans),30 Wu Shao She (syn. Wu Xiao She, Sheng Wu Shao She, parts of the snake Zaocys dhumnades),30 and Yu Dan (fish gallbladder).120122

Finally and most importantly, the use of a few TCM products caused serious hepatotoxicity in some susceptible patients resulting in a severe clinical course with additional risk for acute liver failure, LTX requirement, and lethality.22,24,2830,41,51 Between 1992 and 2008, in Seoul (Korea) alone 24 patients underwent LTX due to acute toxic hepatitis caused by herbal medicine and preparations.28 This is unacceptable because the benefits of herbal TCM products are at present only rarely and inadequately documented.4,5 For the sake of the consumer, a stringent evaluation of the risk/benefit ratio based on results of multicenter, randomized, double-blind, placebo-controlled clinical trials should be the primary goal.4 The future practice of pharmacovigilance and risk control of TCM herbs and drugs in China are promising.117


In a few susceptible individuals, some commonly used herbal TCM products may rarely cause hepatotoxicity with the risk of a severe clinical course with acute liver failure, the requirement for LTX, and potential lethality. This necessitates a stringent evaluation of the risk/benefit ratio for any prospective treatment with herbal TCM products, based on results of multicenter, randomized, double-blind, placebo-controlled clinical trials.
