Nutr Res Pract 2023; 17:1113-1127. [PMID: 38053830 PMCID: PMC10694424 DOI: 10.4162/nrp.2023.17.6.1113] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/05/2023] [Revised: 08/02/2023] [Accepted: 09/08/2023] [Indexed: 12/07/2023] Open
Abstract
BACKGROUND/OBJECTIVES Excessive alcohol consumption has harmful health effects, including alcohol hangovers and alcohol-related liver disease. Therefore, methods to accelerate the alcohol metabolism are needed. Laurus nobilis is a spice, flavoring agent, and traditional herbal medicine against various diseases. This study examined whether the standardized aqueous extract of L. nobilis leaves (LN) accelerates the alcohol metabolism and protects against liver damage in single-ethanol binge Sprague-Dawley (SD) rats. MATERIALS/METHODS LN was administered orally to SD rats 1 h before ethanol administration (3 g/kg body weight [BW]) at 100 and 300 mg/kg BW. Blood samples were collected 0.5, 1, 2, and 4 h after ethanol administration. The livers were excised 1 h after ethanol administration to determine the hepatic enzyme activity. The alcohol dehydrogenase (ADH), aldehyde dehydrogenase (ALDH), superoxide dismutase (SOD), and glutathione peroxidase (GPx) activities in the liver tissue were measured. RESULTS LN decreased the serum ethanol and acetaldehyde levels in ethanol-administered rats. LN increased the hepatic ADH and ALDH activities but decreased the alanine aminotransferase, aspartate aminotransferase, and gamma-glutamyl transferase activities in the ethanol-administered rats. In addition, LN inhibited lipid peroxidation and increased the activities of SOD and GPx. CONCLUSIONS LN modulates the mediators of various etiological effects of excessive alcohol consumption and enhances the alcohol metabolism and antioxidant activity, making it a potential candidate for hangover treatments.

Abstract
Hepatic alcohol clearance is a key factor to overcome alcohol hangovers, and over the period, alcohol hangovers may lead to inflammation and oxidative stress. Natural food products with high antioxidant and anti-inflammatory effects might contribute to hepatic alcohol clearance, a hypothesis in this study. The present study aimed to evaluate the influence of turmeric (Curcuma longa L., Zingiberaceae) is an herbal product having antioxidant and anti-inflammatory activities, on alcohol metabolism using binge alcohol drinking rat model. In vivo investigations revealed that pretreatment with turmeric extract enhanced alcohol dehydrogenase (ADH) and aldehyde dehydrogenase (ALDH) activities upon binge ethanol (3 g/kg). Additionally, pretreatment with turmeric extract regulated CYP2E1 activity and levels of reactive oxygen species (ROS), Bax, Bcl-2, and inflammatory mediators like IL-1β, IL-6, and TNF-α. Moreover, turmeric extract upregulated superoxide dismutase, catalase, and glutathione peroxidase activities in liver tissues. Together, these observations shed light on the potential beneficial effects of turmeric extract against acute liver toxicity. The results offer an alternative natural functional food product, turmeric extract, to prevent the negative implications of binge drinking.

Perspectives of East Asian patients and physicians on complementary and alternative medicine use for inflammatory bowel disease: results of a cross-sectional, multinational study. Intest Res 2022; 20:192-202. [PMID: 35508953 PMCID: PMC9081987 DOI: 10.5217/ir.2020.00150] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 11/24/2020] [Accepted: 03/12/2021] [Indexed: 11/24/2022] Open
Abstract
Background/Aims Complementary and alternative medicine (CAM) is prevalent in East Asia. However, information on CAM in East Asian patients with inflammatory bowel disease (IBD) is scarce. We aimed to profile the prevalence and pattern of CAM use among East Asian IBD patients and to identify factors associated with CAM use. We also compared physicians’ perspectives on CAM. Methods Patients with IBD from China, Japan, and South Korea were invited to complete questionnaires on CAM use. Patient demographic and clinical data were collected. Logistic regression analysis was applied for predictors of CAM use. Physicians from each country were asked about their opinion on CAM services or products. Results Overall, 905 patients with IBD participated in this study (China 232, Japan 255, and South Korea 418). Approximately 8.6% of patients with IBD used CAM services for their disease, while 29.7% of patients sought at least 1 kind of CAM product. Current active disease and Chinese or South Korean nationality over Japanese were independent predictors of CAM use. Chinese doctors were more likely to consider CAM helpful for patients with IBD than were Japanese and South Korean doctors. Conclusions In 8.6% and 29.7% of East Asian patients with IBD used CAM services and products, respectively, which does not differ from the prevalence in their Western counterparts. There is a significant gap regarding CAM usage among different Asian countries, not only from the patients’ perspective but also from the physicians’ point of view.

Abstract
Background Tuberculosis (TB) is one of the leading causes of death globally, and the rise in drug-resistant forms of TB has become a significant threat. Subsequently, it is crucial to explore new, effective and safe anti-TB agents. This study aimed at conducting phytochemical screening, antimycobacterial activity, and acute toxicity of the selected plant species’ crude extracts to assess their toxicological potentials and efficacies against TB. Methods The aqueous and methanol/dichloromethane (DCM) (1:1) extracts of each selected plant species were subjected to phytochemical screening and antimycobacterial activity using microplate alamar blue assay. For acute toxicity, a single dose (2000 mg/kg) of the aqueous extracts was orally administered to each animal following the Organization for Economic Cooperation and Development (OECD) guidelines No. 425 and then observed for 14 days. The animals were closely observed on the general behavior and clinical signs of toxicity, and body weights were recorded. After the termination of the experiment, hematological, biochemical, and histopathological analyses were performed. Results The extracts contained alkaloids, flavonoids, tannins, saponins, steroids, terpenoids, resins, cardiac glycosides, phenolic compounds, and coumarins. Aqueous extracts showed moderate to weak activity against the susceptible (H37Rv) M. tuberculosis strain and weak activity against the MDR-TB strain with Minimum Inhibitory Concentrations (MIC μg/mL) ranging from 293.0–2344.0 and 1172.0–4688.0, respectively. Methanol/DCM extracts showed significant to moderate activity against the susceptible TB strain and moderate to weak activity against the MDR-TB strain with MIC (μg/mL) ranging from 98.0–586.0 and 293.0–781.0, respectively. One mortality was recorded from the A. coriaria treated group following the acute toxicity tests, but the LD50 of all the extracts was estimated to be above 2000 mg/kg. Histopathological analyses did not show any significant lesions in the examined organs except those from the A. coriaria treated group. Conclusion Phytochemical screening of the extracts revealed the presence of alkaloids, tannins, saponins, flavonoids, steroids, terpenoids, resins, cardiac glycosides, phenolic compounds, and coumarins. All the methanol/DCM extracts of the plant species studied have promising antimycobacterial activity. The selected plant extracts studied exhibited low acute toxicity levels except for A. coriaria and could be safe for formulations into herbal products.

Abstract
BACKGROUND Herbal medication is a worldwide and ancient practice, mostly in developing countries, where a large part of the population is involved in this practice. Hence, studies must be conducted to evaluate their safety and efficiency to avoid or prevent toxicological risks due to their usage. In Togo, Carissa spinarum is a medicinal plant belonging to Apocynaceae family, used as an aphrodisiac or to heal some ailments including malaria, sickle cell anemia, hypertension, pain, and asthma. Notwithstanding its several ethnomedicinal benefits, just a few toxicological data associated with its chronic use are available. OBJECTIVE Therefore, this study aims to assess the toxicity of an ethanolic root extract of Carissa spinarum in Wistar rats. METHODS The 90-day oral toxicity process following OECD TG 408 guidelines is used. Male Wistar rats received Carissa spinarum root hydroethanolic extract at 500 and 1000 mg/kg for 90 days by oral gavage. Body weight changes, hematological and blood biochemical parameters, organ weight changes, malondialdehyde as a lipoperoxidation marker expressed according to tissue proteins, and histopathology of vital organs were assessed. RESULTS No signs of toxicity or mortality were observed during the 90 days experiment. Hematological parameters have not shown any treatment-related abnormalities. According to biochemical parameters, an increase in the chloride ion level was observed at 1000 mg/kg (p < 0.01). There was no significant difference between the treated groups and the control group concerning the malondialdehyde concentration, body weight, and organ relative weight. No changes in necropsy and histopathology of vital organs associated with extract treatment were observed. CONCLUSION The results indicated that an ethanolic root extract of Carissa spinarum does not cause adverse effects, which can lead to Wistar rats' death after 90-day oral administration at 500 and 1000 mg.

Abstract
Carissa spinarum L. (Apocynaceae) is used traditionally, in Africa, to treat many diseases such as malaria, sickle cell anemia, epilepsy, helminthoses, and sexual weakness. The aim of this study is to investigate the cytotoxicity on Artemia salina, the acute and subacute (28 days) oral toxicity of C. spinarum hydroalcoholic root extract on Wistar rats. The cytotoxicity was performed on A. salina larvae. The acute and subacute toxicity was performed using Organization of Economic Cooperation and Development guideline. Malondiadehyde as lipoperoxidation marker was evaluated and expressed according to tissue proteins. The cytotoxicity has shown that the lethal concentration 50 (LC50) was 0.9 mg/mL. The limit test dose of 5000 mg/kg did not provoke death or toxicity signs. For the subacute toxicity, no signs of toxicity or mortality were observed during the experiment. Results of biochemical and hematological parameters have not shown any treatment-related abnormalities, except a significant decrease of alkaline phosphatase at 1000 mg/kg (P < .05) and an increase of chloride ion level at 500 mg/kg (P < .01). There was no significant difference between the treated group and the control group concerning the malondialdehyde concentration, the body weight, and the organs relative weight (P < .05), except for testis at 500 mg/kg (P < .05). According to our results, the hydroalcoholic extract of C. spinarum roots is safe when administrated at 500 mg and 1000 mg/kg to Wistar rats for 28 days.

Abstract
Accumulative alcohol hangovers cause liver damage through oxidative and inflammatory stress. Numerous antioxidant and anti-inflammatory reagents have been developed to reduce alcohol hangovers, but these reagents are still insignificant and have limitations in that they can cause liver toxicity. Oyster hydrolysate (OH), another reagent that has antioxidant and anti-inflammatory activity, is a product extracted through an enzymatic hydrolysis process from oysters (Crassostrea gigas), which can be easily eaten in meals. This study was aimed at determining the effects of OH on alcohol metabolism, using a single high dose of ethanol (EtOH) administered to rodents, by monitoring alcohol metabolic enzymes, oxidative stress signals, and inflammatory mediators. The effect of tyrosine-alanine (YA) peptide, a main component of OH, on EtOH metabolism was also identified. In vitro experiments showed that OH pretreatment inhibited EtOH-induced cell death, oxidative stress, and inflammation in liver cells and macrophages. In vivo experiments showed that OH and YA pre-administration increased alcohol dehydrogenase, aldehyde dehydrogenase, and catalase activity in EtOH binge treatment. In addition, OH pre-administration alleviated CYP2E1 activity, ROS production, apoptotic signals, and inflammatory mediators in liver tissues. These results showed that OH and YA enhanced EtOH metabolism and had a protective effect against acute alcohol liver damage. Our findings offer new insights into a single high dose of EtOH drinking and suggest that OH and YA could be used as potential marine functional foods to prevent acute alcohol-induced liver damage.

Abstract
Objectives This study was conducted to development of hazardous materials management standards for the decoction type of personalized herbal medicines (PHMs). Methods This study was conducted in two stages. We searched documents about criteria to use words such as 'Herb', 'Herbal medicine', and 'Botanical Drug’ and summarized the results. We organized the committee consisted of seven experts, and held two meetings to reach an agreement on hazardous management standards of the decoction type of PHMs. Results The seven documents were presented in the literature review and six items related to hazardous management standards of decoction were identified. The second expert meeting brought that a total of six items, including heavy metal, pesticide residues, sulfur dioxide, benzopyrene, mycotoxin, and micro-organism limits, were selected for safety management of decoction type of PHMs. Also, the criteria and test methods for each standard were suggested for monitoring the decoction type of PHMs. Conclusion The study suggested hazardous material management standards and criteria for the decoction types of PHMs. In the future, it would be necessary to conduct a pilot test to ensure the validity and credibility of the safety management standard and criteria. Furthermore, the government level safety management system should be introduced to verify the safety of decoction medicines.

Abstract
Launaea taraxacifolia (Asteraceae) is a widely used vegetable in West Africa. It is used in traditional healing of many diseases such as hypertension, anemia, diabetes, and bleeding. The aim of this study is to investigate the cytotoxicity and the acute and subacute (28 days) oral toxicity of L. taraxacifolia hydroethanolic leaves extract on male Wistar rats. The LC50 values of L. taraxacifolia on brine shrimp were 0.142 ± 0.11 mg/mL. The limit test dose of 5000 mg/kg did not provoke death or toxicity signs in the rats tested during the observation period. For 28 days subacute toxicity at 500 and 1000 mg/kg body weight, no signs of toxicity or mortality were observed during the experiment. There was no significant difference between the treated groups and the control group concerning the body and the relative organs weight (P > .05). Results of biochemical and hematological parameters did not show any treatment-related abnormalities. According to our results, the hydroethanolic extract of L. taraxacifolia leaves, at 500 and 1000 mg/kg body weight, is safe when administrated to male Wistar rats for 28 days.

Abstract
BACKGROUND In recent times, herbals or phytomedicines have become very popular due to their global acceptance as a complementary and alternative remedy. While modern drugs are commercially available only after laboratory validations, clinical trials, as well as approval from drug regulatory authorities, majority of the marketed herbal products lack such scientific evidence of efficacy and safety. This results in herb or herb-drug interaction induced unfavorable clinical outcomes without crucial documentation on their temporal relations and concomitant use. METHODS An online literature search for peer-reviewed articles was conducted on the PubMed, Europe PMC, Medline and Google Scholar portals, using the phrases: complementary & alternative medicine, traditional Chinese medicine, herb-drug interaction, mechanisms of herb-drug interaction, herb-induced toxicity, herbal hepatotoxicity and causality, traditional medicine, viral hepatitis, etc. Results The retrieved data showed that globally, patients are attracted to herbal remedies with the misconception that these are completely safe and therefore, use them simultaneously with prescription drugs. Notably, there exists a potential risk of herb-drug interactions leading to some adverse side effects, including hepatotoxicity. The toxicological effect of a drug or herb is due to the inhibition of drug metabolizing enzymes (e.g., cytochrome P450), including interactions with certain prescription drugs through various mechanisms. Several cases of hepatotoxicity due to use of herbals in viral hepatitis-related liver diseases have been recently reported. However, limited experimental data and clinical evidence on herbal pharmacokinetics hamper the evaluation and reporting of adverse reactions and the underlying mechanisms. CONCLUSION Herb-drug interaction related morbidity is thus an emerging serious public health issue with broad implications for clinicians, pharmaceutical industries and health authorities. Nonetheless, despite increasing recognition of herb-drug interaction, a standard system for interaction prediction and evaluation is still nonexistent. This review article discusses the herb-drug interactions related hepatotoxicity and underlying mechanisms, including drug metabolizing enzymes and their regulation.

Abstract
Our previous studies have investigated the systematic pharmacokinetic characteristics, biological activities, and toxicity of arctigenin. In this research, the potential toxicities of arctigenin in beagle dogs were investigated via repeated 28-day subcutaneous injections. Beagle dogs were randomly divided into control, vehicle [polyethylene glycol (PEG)], and arctigenin 6, 20, 60 mg/kg treated groups. The whole experimental period lasted 77 days, including adaptive period (35 days), drug exposure period (animals were treated with saline, PEG, or arctigenin for 28 consecutive days), and recovery period (14 days). Arctigenin injection (60 mg/kg) affected the lymphatic hematopoietic, digestive, urinary, and cardiovascular systems, and all the impact on these tissues resulted in death in five dogs (three female and two male dogs); 20 mg/kg arctigenin injection resulted in toxic reactions of the lymphatic hematopoietic and digestive systems; and 6 mg/kg arctigenin and PEG injection did not lead to significant toxic reactions. Meanwhile, there were no sexual differences of drug exposure and accumulation when dogs underwent different dosages. As stated previously, the toxic target organs of arctigenin administration include lymphatic hematopoietic, digestive (liver and gallbladder), urinary (kidney), and cardiovascular (heart) systems, and the no observed adverse effect level (NOAEL) of arctigenin is less than 6 mg/kg.

Untargeted Safety Pharmacology Screen of Blood-Activating and Stasis-Removing Patent Chinese Herbal Medicines Identified Nonherbal Ingredients as a Cause of Organ Damage in Experimental Models. Front Pharmacol 2019; 10:993. [PMID: 31607901 PMCID: PMC6757273 DOI: 10.3389/fphar.2019.00993] [Citation(s) in RCA: 4] [Impact Index Per Article: 0.8] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/26/2018] [Accepted: 08/05/2019] [Indexed: 12/22/2022] Open
Abstract
Blood activation and stasis removal from circulation is a central principle for treatment of syndromes related to cerebral and cardiovascular diseases in Chinese herbal medicine. However, blood-activating and stasis-removing patent Chinese herbal medicine (BASR-pCHM) widely used with or without prescription in China and elsewhere are highly variable in composition and manufacture standard, making their safety assessment a challenging task. We proposed that an integrated evaluation of multiple toxicity parameters of BASR-pCHM would provide critical reference and guidelines for their safe clinical application. Examination of standardized extracts from 58 compound BASR-pCHM in vivo in VEGFR2-luc mice and in vitro in cardiac, renal, and hepatic cells identified Naoluotong capsule (NLTC) as a potent organ/cell damage inducer. Composition analysis revealed that NLTC was the one that contained nonherbal ingredients among the BASR-pCHM collection. In vivo and in vitro experiments confirmed that NLTC, as well as its chemical supplement tolperisone hydrochloride, caused organ and cell damage by reducing cell viability, mitochondrial mass/activity, while the NLTC herbal components did not. Taken together, our study showed that safety evaluation of patent herbal medicines already on market is still necessary and urgently needed. In addition, chemical/herbal interactions should be considered as an important contributor of potential toxicity when evaluating the safety of herbal medicine.

Abstract
The use of botanicals for maintaining good health and preventing diseases is undisputed. The claimed health benefits of natural health products and herbal medicines are based on traditional claims, positive results obtained in preclinical studies and early phase clinical trials that are not backed by safety and efficacy evidences approved by regulatory agencies. Although, the popularity of botanicals is growing, health care practitioners of modern medicine seldom recommend their use because of ill equipped database of their safety and potency. This review discusses problems that preclude botanicals from integrating into the mainstream contemporary therapeutics and cues that provide impetus for their realisation.

Abstract
Traditional herbal products are widely used in Australia to treat a broad range of conditions and diseases. It is popularly believed that these products are safer than prescribed drugs. While many may be safe, it is worrying that the specific effects and harmful interactions of a number of their components with prescription medications is not well understood. Some traditional herbal preparations contain heavy metals and toxic chemicals, as well as naturally occurring organic toxins. The effects of these substances can be dire, including acute hepatic and renal failure, exacerbation of pre-existing conditions and diseases, and even death. The content and quality of herbal preparations are not tightly controlled, with some ingredients either not listed or their concentrations recorded inaccurately on websites or labels. Herbal products may also include illegal ingredients, such as ephedra, Asarum europaeum (European wild ginger) and endangered animal species (eg, snow leopard). An additional problem is augmentation with prescription medications to enhance the apparent effectiveness of a preparation. Toxic substances may also be deliberately or inadvertently added: less expensive, more harmful plants may be substituted for more expensive ingredients, and processing may not be adequate. The lack of regulation and monitoring of traditional herbal preparations in Australia and other Western countries means that their contribution to illness and death is unknown. We need to raise awareness of these problems with health care practitioners and with the general public.

Abstract
BACKGROUND There is an increasing interest in complementary and alternative medicine (CAM) in patients with chronic diseases, including those with inflammatory bowel disease (IBD). Patients may turn to CAM when conventional therapies are inadequate or associated with side effects for symptomatic relief or to regain control over their disease. The objectives were to explore CAM use and perceived effects in IBD patients in comparison with a control group. METHODS A cross-sectional, multicenter, controlled study was carried out. IBD patients were invited from 12 IBD clinics in Sweden. Controls were selected randomly from a residence registry. A study-specific questionnaire was used for data collection. RESULTS Overall, 48.3% of patients with IBD had used some kind of CAM during the past year compared with 53.5% in controls (P=0.025, adjusted for age, sex, geographic residence, and diet). The most frequently used CAM among IBD patients was massage (21.3%), versus controls (31.4%) (adjusted P=0.0003). The second most used CAM was natural products, 18.7% in IBD patients versus 22.3% of the controls (unadjusted P=0.018). In all, 83.1% of the patients experienced positive effects from CAM and 14.4% experienced negative effects. CONCLUSION Overall, 48.3% of Swedish IBD patients used some kind of CAM and controls used CAM significantly more. Natural products were used by one-fifth of the patients and even more by controls. This is notable from a patient safety perspective considering the possible risks of interactions with conventional medication. In all, 40% of the patients reported adverse events from conventional medicine. Patients experienced predominantly positive effects from CAM, and so did controls.

Abstract
BACKGROUND No online current list of potentially life-threatening, hepatotoxic herbs and dietary supplements based on PubMed case reports exists in a summarized tabular form. METHODS Documented case reports of herbs or dietary supplements (DS; includes herbs) appearing to contribute to liver injury were used to create an online "DS Toxic Table" of potentially hepatotoxic herbs and dietary supplements (PubMed, 1966 to June, 2016, and cross-referencing). The spectrum of DS induced liver injuries (DSILI) included elevated liver enzymes, hepatitis, steatosis, cholestasis, hepatic necrosis, hepatic fibrosis, hepatic cirrhosis, veno-occlusive disease, acute liver failure requiring a liver transplant, and death. RESULTS Over the past 50 years, approximately 21 herbs (minus germander and usnic acid that are no longer sold) and 12 dietary supplements (minus the nine no longer sold and vitamin A & niacin due to excess intake) posed a possible risk for liver injures in certain individuals. The herbs with the most number of reported publications (but not cases studies) in descending order, were germander, black cohosh, kava extract, and green tea extract. CONCLUSION These online DS Toxic Tables will contribute to continued Phase IV post marketing surveillance to detect possible liver toxicity cases and serve to forewarn consumers, clinicians, and corporations.

Abstract
Lithospermum erythrorhizon has long been used as a traditional oriental medicine. In this study, the acute and 28-day subacute oral dose toxicity studies of hexane extracts of the roots of L. erythrorhizon (LEH) were performed in Sprague-Dawley rats. In the acute toxicity study, LEH was administered once orally to 5 male and 5 female rats at dose levels of 500, 1,000, and 2,000 mg/kg. Mortality, clinical signs, and body weight changes were monitored for 14 days. Salivation, soft stool, soiled perineal region, compound-colored stool, chromaturia and a decrease in body weight were observed in the extract-treated groups, and no deaths occurred during the study. Therefore, the approximate lethal dose (ALD) of LEH in male and female rats was higher than 2,000 mg/kg. In the subacute toxicity study, LEH was administered orally to male and female rats for 28 days at dose levels of 25, 100, and 400 mg/kg/day. There was no LEH-related toxic effect in the body weight, food consumption, ophthalmology, hematology, clinical chemistry and organ weights. Compound-colored (black) stool, chromaturia and increased protein, ketone bodies, bilirubin and occult blood in urine were observed in the male and female rats treated with the test substance. In addition, the necropsy revealed dark red discoloration of the kidneys, and the histopathological examination showed presence of red brown pigment or increased hyaline droplets in the renal tubules of the renal cortex. However, there were no test substance-related toxic effects in the hematology and clinical chemistry, and no morphological changes were observed in the histopathological examination of the kidneys. Therefore, it was determined that there was no significant toxicity because the changes observed were caused by the intrinsic color of the test substance. These results suggest that the no-observed-adverse-effect Level (NOAEL) of LEH is greater than 400 mg/kg/day in both sexes.

Abstract
Plants are natural producers of chemical substances, providing potential treatment of human ailments since ancient times. Some herbal chemicals in medicinal plants of traditional and modern medicine carry the risk of herb induced liver injury (HILI) with a severe or potentially lethal clinical course, and the requirement of a liver transplant. Discontinuation of herbal use is mandatory in time when HILI is first suspected as diagnosis. Although, herbal hepatotoxicity is of utmost clinical and regulatory importance, lack of a stringent causality assessment remains a major issue for patients with suspected HILI, while this problem is best overcome by the use of the hepatotoxicity specific CIOMS (Council for International Organizations of Medical Sciences) scale and the evaluation of unintentional reexposure test results. Sixty five different commonly used herbs, herbal drugs, and herbal supplements and 111 different herbs or herbal mixtures of the traditional Chinese medicine (TCM) are reported causative for liver disease, with levels of causality proof that appear rarely conclusive. Encouraging steps in the field of herbal hepatotoxicity focus on introducing analytical methods that identify cases of intrinsic hepatotoxicity caused by pyrrolizidine alkaloids, and on omics technologies, including genomics, proteomics, metabolomics, and assessing circulating micro-RNA in the serum of some patients with intrinsic hepatotoxicity. It remains to be established whether these new technologies can identify idiosyncratic HILI cases. To enhance its globalization, herbal medicine should universally be marketed as herbal drugs under strict regulatory surveillance in analogy to regulatory approved chemical drugs, proving a positive risk/benefit profile by enforcing evidence based clinical trials and excellent herbal drug quality.

Abstract
Background The use of Complementary and Alternative Medicine (CAM) in Inflammatory Bowel Disease (IBD) is increasing. Although CAM often improves patients’ well-being, it can also lead to side-effects and interactions with conventional medications. Research on patients with IBD in Sweden who have experiences of CAM is sparse. More studies are needed to enhance awareness of and improve communication about CAM. The aim of this study was to describe experiences of CAM in the healthcare context reported by patients with IBD. Methods Fifteen patients with IBD, eight with Crohn’s disease (CD) and seven with ulcerative colitis (UC), were recruited. Semi-structured qualitative interviews were conducted and qualitative content analysis was performed. Results The analysis revealed the theme Knowledge and communication lead to participation in the area of CAM based on three categories; CAM use, Communication and Self-care. Patients with IBD wanted to be asked about CAM to be able to start a dialogue, as some perceived being treated in a disparaging manner and not taken seriously when raising the subject. Healthcare professionals (HCPs) need to be aware of this in order to meet and understand patient needs. Patients with IBD found it easier to communicate about CAM with the IBD nurses than physicians and dietary changes was one important CAM treatment. Conclusions The finding that it was easier to discuss CAM with nurses than physicians emphasizes the important role of the IBD nurse in communication and monitoring patients’ CAM use. Patients wanted to be asked about CAM to be able to start a dialogue, as some perceived not taken seriously when raising the subject. Furthermore, HCPs need to understand that many patients with IBD regard dietary changes as an important part of CAM treatment. Further research in these areas is needed.

Abstract
INTRODUCTION The high prevalence of the use of traditional herbs among patients with cancer is a cause for concern with regard to potentially adverse interactions with conventional oncology treatments. In this study, we explore herbal use among patients with cancer in northern Israel who are referred by their health care providers to complementary and traditional medicine (CTM) consultations provided to them within the conventional oncology department. The study's objectives were to identify which herbs patients use and to examine the scope of current research on the efficacy and safety regarding the identified herbs. PATIENTS AND METHODS Herbal use by patients receiving oncology care was assessed prospectively from July 2009 to July 2012 by integrative physicians (IPs) trained in herbal medicine. Historical, ethnobotanical, basic research, and clinical data regarding the identified herbs were explored by using a keyword search in PubMed and Middle Eastern ethnohistorical literature. RESULTS Disclosure of herbal use was reported by 154 of the 305 patients (50.5 %) interviewed by IPs. The use of 85 single herbs and 30 different herbal formulas was documented during the initial or follow-up IP assessments. Patients reported 14 quality of life-associated indications for herbal use. The ten most prevalent herbs displaying in vitro/in vivo anticancer activity and nine other herbs were preliminarily assessed concerning potential risks, safety, and interaction with chemotherapy. CONCLUSIONS Herbal use by patients with cancer in northern Israel is widespread and calls for further study in order to address issues of safety and effectiveness. We recommend constructing a multinational and multidisciplinary team of researchers with ethnopharmacological and clinical expertise that will explore the use of herbs among patients with cancer in a cross-cultural perspective attuned with patients' affinity to traditional herbal medicine.

Abstract
Publications linking hepatotoxicity to the use of herbal preparations are escalating. Herbal teas, traditional Chinese medicines (TCMs) and dietary supplements have been shown to contain pyrrolizidine alkaloids (PAs). Acute PA toxicosis of the liver can result in sinusoidal-obstruction syndrome, also known as veno-occlusive disease (VOD). This paper describes a sensitive and robust method for the detection of targeted PAs and their N-oxides (PANOs) in herbal products (selected herbal teas and TCMs) sourced within Ireland. The sample preparation includes a simple acidic extraction with clean-up via solid-phase extraction (SPE). Sample extracts were accurately analysed by using LC-ESI-MS/MS applying for the first time a pentafluorophenyl (PFP) core-shell column to the chromatographic separation of PAs and PANOs. The method was validated for selectivity, taking into consideration matrix effects, specificity, linearity, precision and trueness. Limits of detection (LOD) and limits of quantitation (LOQ) were quantified for all PAs and PANOs ranging from 0.4 to 1.9 µg kg⁻¹ and from 1.3 to 6.3 µg kg⁻¹, respectively. In this study 10 PAs and four PANOs were targeted because they are commercially available as reference standards. Therefore, this study can only report the levels of these PAs and PANOs analysed in the herbal teas and TCMs. The results reported represent the minimum levels of PAs and PANOs present in the samples analysed; commercially available herbal teas (n = 18) and TCMs (n = 54). A total of 50% herbal teas and 78% Chinese medicines tested positive for one or more PAs and/or PANOs included within this study, ranging from 10 to 1733 and from 13 to 3668 µg kg⁻¹, respectively.

Abstract
BACKGROUND There has been a global rise in the use of natural health products (NHPs). Proper regulation of NHPs is pivotal to ensure good quality control standards, enhance consumers' safety and facilitate their integration into modern healthcare systems. There is scarcity of published data on the prevalence of NHPs usage among the general Kuwaiti population. Hence, this study was designed to determine awareness, patterns of use, general attitude and information requirements about NHPs among the public in Kuwait. METHODS A descriptive cross-sectional survey was performed using a pretested self-administered questionnaire on a sample of 1300 Kuwaiti individuals, selected from six governorates in Kuwait using a multistage stratified clustered sampling. Descriptive and multivariate logistic regression analysis were used in data analysis. RESULTS The response rate was 90.2%. NHPs were thought to be herbal remedies by most of participants (63.5%), followed by vitamins/minerals (40.5%), traditional medicines (21.1%), probiotics (14.9%), amino acids and essential fatty acids (7.2%), and homeopathic medicines (5.6%). NHPs usage was reported by 71.4% (95% CI: 68.8-74.0%) of respondents, and mostly associated with females (OR: 1.90; 95% CI: 1.44-2.51). Herbal remedies were the most commonly used (41.3%; 95% CI: 38.5-44.2%). The most common reasons for using NHPs were to promote and maintain health and to prevent illness and build immune system. Family members and/or friends and mass media were the main sources for providing information about NHPs. About 18% of consumers have experienced a side effect due to using a NHP. Attitudes toward NHPs were generally positive; with more than 75% of participants believing that the Ministry of Health in Kuwait should regulate the claims made by the manufacturers of NHPs and it is important to talk to a medical doctor or a pharmacist prior to using NHPs. Most of the respondents showed increased interest to acquire knowledge about different types of information related to NHPs. CONCLUSIONS The prevalence of use of NHPs among Kuwaiti population is high. The present findings have major public health policy implications for Kuwait. Therefore, there is an apparent need to establish effective health education programs and implement better and more regulated NHPs use policies in Kuwait.

Abstract
Background Complementary and alternative medicine (CAM) use in patients with IBD is on the increase. Patients report they use CAM when their condition is unresponsive to conventional medication or when they suffer from side-effects, negative stress and disease-related concerns. CAM use may improve patients’ well-being but it can also lead to side-effects and interactions with conventional medications. Research on attitudes to and experiences of CAM among healthcare professionals working with IBD patients is not well studied. Studies in this area could lead to enhanced awareness of and improved communication about CAM between care staff and IBD patients. The aim of this study was to explore IBD professionals’ attitudes to and experience of CAM. Methods Sixteen physicians and nurses, 26–70 years old, who had worked with IBD patients for 1–42 years, were recruited. Semi-structured qualitative interviews were conducted. Qualitative content analysis was performed. Results Participants stated patients used CAM to improve their well-being generally and there conditions specifically. Participants had a positive attitude towards CAM and respected their patients’ decision to use it, but reported a lack of CAM knowledge. They required education about CAM to be able to meet patients’ needs and provide adequate information. The result of this study indicates that there is a need for CAM education to be implemented in nursing and medical school. Conclusions All participants had experience of IBD patients who had used CAM in an attempt to achieve improvement and well-being. Attitudes to CAM were mainly positive, although a problematic aspect was lack of knowledge and evidence in relation to CAM. Implementing CAM education in nursing and medical school will allow healthcare professionals to gain an understanding of therapies widely used by patients with IBD. In clinical practice, using a standard questionnaire regarding CAM use allow healthcare professionals to better understand their patients’ wishes and current CAM use.

Abstract
Herbal and dietary supplement use is common. Most marketed products consist of complex mixtures. Although they are perceived as safe, instances of hepatotoxicity attributable to these products underscore their potential for injury, but the exact component that is responsible for injury is difficult to discern. The lenient regulatory environment in the United States, which opens the possibility of adulteration and contamination, adds to the challenge of disease attribution. Although many different herbal and dietary supplements have been reported to cause liver injury, in the United States, products used for bodybuilding and weight loss are the most commonly implicated.

Abstract
BACKGROUND AND OBJECTIVES Alternative explanations are common in suspected drug-induced liver injury (DILI) and account for up to 47.1% of analyzed cases. This raised the question of whether a similar frequency may prevail in cases of assumed herb-induced liver injury (HILI). METHODS We searched the Medline database for the following terms: herbs, herbal drugs, herbal dietary supplements, hepatotoxic herbs, herbal hepatotoxicity, and herb-induced liver injury. Additional terms specifically addressed single herbs and herbal products: black cohosh, Greater Celandine, green tea, Herbalife products, Hydroxycut, kava, and Pelargonium sidoides. We retrieved 23 published case series and regulatory assessments related to hepatotoxicity by herbs and herbal dietary supplements with alternative causes. RESULTS The 23 publications comprised 573 cases of initially suspected HILI; alternative causes were evident in 278/573 cases (48.5%). Among them were hepatitis by various viruses (9.7%), autoimmune diseases (10.4%), nonalcoholic and alcoholic liver diseases (5.4%), liver injury by comedication (DILI and other HILI) (43.9%), and liver involvement in infectious diseases (4.7%). Biliary and pancreatic diseases were frequent alternative diagnoses (11.5%), raising therapeutic problems if specific treatment is withheld; pre-existing liver diseases including cirrhosis (9.7%) were additional confounding variables. Other diagnoses were rare, but possibly relevant for the individual patient. CONCLUSION In 573 cases of initially assumed HILI, 48.5% showed alternative causes unrelated to the initially incriminated herb, herbal drug, or herbal dietary supplement, calling for thorough clinical evaluations and appropriate causality assessments in future cases of suspected HILI.

Abstract
Drug and substance abuse remains a major medical problem. Alcohol use, abuse and dependence are highly prevalent conditions. Alcohol related liver disease can present as simple steatosis, steatohepatitis, alcoholic hepatitis or liver cirrhosis. Paracetamol hepatotoxicity secondary to accidental or deliberate overdose is another common problem. While the adverse cardiovascular, neurological, renal and psychiatric consequences of various illicit substance abuses are widely studied and publicized, less attention has been directed towards possible hepatotoxic effects. Illicit drug abuse can cause a range of liver abnormalities ranging from asymptomatic derangement of liver function tests to fulminant hepatic failure. This article reviews the epidemiology, risk factors, clinical manifestations, pathogenesis, investigations, management and prognostic factors of alcohol related liver disease and paracetamol hepatotoxicity as well as the current knowledge pertaining to hepatotoxicity of the more commonly used illicit substances including cannabis, amphetamine type stimulants, cocaine, khat chewing and complementary and alternate medicine.

Abstract
Fermented Rhus verniciflua stem bark (FRVSB) extract, an urushiol-free extract of Rhus verniciflua Stokes (RVS) fermented with Fomitella fraxinea, has various biological activities. The present study was carried out to investigate the potential toxicity of the FRVSB extract following single and repeated oral administration to Sprague-Dawley rats. In the single dose toxicity study, the FRVSB extract was administered orally to male and female rats at single doses of 0, 2500, 5000, and 10,000mg/kg. No animals died and no toxic changes were observed in clinical signs, body weight, and necropsy findings during the 15-day period following administration. In the repeated dose toxicity study, the FRVSB extract was administered orally to male and female rats for 90days at doses of 0, 556, 1667, and 5000mg/kg/day. There were no treatment-related adverse effects in clinical signs, body weight, food and water consumption, ophthalmic examination, urinalysis, hematology, serum biochemistry, necropsy findings, organ weight, and histopathology at any dose tested. The approximate lethal dose of the FRVSB extract was >10,000mg/kg in both genders, the oral no-observed-adverse-effect level of the FRVSB extract was >5000mg/kg/day in both genders, and no target organs were identified.

Abstract
This overview of systematic reviews (SRs) aims to evaluate critically the evidence regarding the adverse effects of herbal medicines (HMs). Five electronic databases were searched to identify all relevant SRs, with 50 SRs of 50 different HMs meeting our inclusion criteria. Most had only minor weaknesses in methods. Serious adverse effects were noted only for four HMs: Herbae pulvis standardisatus, Larrea tridentate, Piper methysticum and Cassia senna. The most severe adverse effects were liver or kidney damage, colon perforation, carcinoma, coma and death. Moderately severe adverse effects were noted for 15 HMs: Pelargonium sidoides, Perna canaliculus, Aloe vera, Mentha piperita, Medicago sativa, Cimicifuga racemosa, Caulophyllum thalictroides, Serenoa repens, Taraxacum officinale, Camellia sinensis, Commifora mukul, Hoodia gordonii, Viscum album, Trifolium pratense and Stevia rebaudiana. Minor adverse effects were noted for 31 HMs: Thymus vulgaris, Lavandula angustifolia Miller, Boswellia serrata, Calendula officinalis, Harpagophytum procumbens, Panax ginseng, Vitex agnus-castus, Crataegus spp., Cinnamomum spp., Petasites hybridus, Agave americana, Hypericum perforatum, Echinacea spp., Silybum marianum, Capsicum spp., Genus phyllanthus, Ginkgo biloba, Valeriana officinalis, Hippocastanaceae, Melissa officinalis, Trigonella foenum-graecum, Lagerstroemia speciosa, Cnicus benedictus, Salvia hispanica, Vaccinium myrtillus, Mentha spicata, Rosmarinus officinalis, Crocus sativus, Gymnema sylvestre, Morinda citrifolia and Curcuma longa. Most of the HMs evaluated in SRs were associated with only moderately severe or minor adverse effects.

Abstract
PURPOSE The aim of this overview of systematic reviews is to summarise and critically evaluate the evidence from systematic reviews of the adulteration and contamination of herbal medicinal products (HMPs). METHODS Five electronic databases were searched to identify all relevant systematic reviews. RESULTS Twenty-six systematic reviews met our inclusion criteria. The most commonly HMPs were adulterated or contaminated with dust, pollens, insects, rodents, parasites, microbes, fungi, mould, toxins, pesticides, toxic heavy metals and/or prescription drugs. The most severe adverse effects caused by these adulterations were agranulocytosis, meningitis, multi-organ failure, perinatal stroke, arsenic, lead or mercury poisoning, malignancies or carcinomas, hepatic encephalopathy, hepatorenal syndrome, nephrotoxicity, rhabdomyolysis, metabolic acidosis, renal or liver failure, cerebral edema, coma, intracerebral haemorrhage, and death. Adulteration and contamination of HMPs were most commonly noted for traditional Indian and Chinese remedies, respectively. CONCLUSIONS Collectively these data suggest that there are reasons for concerns with regards to the quality of HMPs. Adulteration and contamination of HMPs can cause serious adverse effects. More stringent quality control and its enforcement seem to be necessary to avoid health risks.

CONCLUSIONS Collectively these data suggest that there are reasons for concerns with regards to the quality of HMPs. Adulteration and contamination of HMPs can cause serious adverse effects. More stringent quality control and its enforcement seem to be necessary to avoid health risks.

Abstract
Objectives: The aim of this study was to investigate the safety and the efficacy of Korean herbal, western and combination medicine use in patients with abnormal liver function tests. Methods: We investigated nerve disease patients with abnormal liver function tests who were treated with Korean herbal, western and combination medicine at Dong-Eui University Oriental Hospital from January 2011 to August 2011. We compared aspartic aminotransferase (AST), alanine aminotransferase (ALT), alkaline phosphatase (ALP) and total bilirubin (T-bil) levels before and after taking medicine and excluded patients who had liver-related disease when admitted. Results: AST and ALT were decreased significantly in patients who had taken herbal, western medicine. AST, ALT and ALP were decreased significantly in patients who had taken combination medicine. Compare to herbal medicine, AST, ALT and ALP were decreased significantly in patients who had taken western medicine, and ALT and ALP were decreased significantly in patients who had taken combination medicine. There were no significant differences between western and combination medicine. Conclusions: This study suggests that prescribed Korean herbal medicine, at least, does not injure liver function for patients’, moreover, it was shown to be effective in patients with abnormal liver function tests.

PHYTOMEDICINE : INTERNATIONAL JOURNAL OF PHYTOTHERAPY AND PHYTOPHARMACOLOGY 2011; 18:1208-1213.

Abstract
Concurrent use of herbal medicine (HM) and conventional medicine (CM) is increasing. However, little is known about the prevalence of drug-induced liver injury (DILI) related to this concurrent use. In order to investigate changes in liver enzymes during concurrent use of HM and CM and to assess the prevalence of DILI related to their concurrent use, we screened for liver injury among inpatients at our institution who were administered both HM and CM for at least 14 days while hospitalized between 2006 and 2010. We used the Council for International Organization of Medical Science (CIOMS) laboratory criteria to define liver injury. Of the 892 patients included in the study, 34 (3.81%) had liver injury on admission and 21 (2.35%) had liver injury at discharge. Of the 48 cases that fulfilled the CIOMS laboratory criteria for liver injury, 34 had preexisting liver injury. The remaining 14 were analyzed, and five were concluded to have DILI, resulting in a prevalence of 5/892 (0.56%, with a 95% confidence interval of 0.07-1.05%). Overall, clinical symptoms of liver injury were mild. We thus contend that concurrent use of HM and CM is relatively safe.

Abstract
OBJECTIVES The objective of this study was to examine the methods used in systematic reviews of safety across a range of complementary therapies to assess the variation in approach and the potential for developing guidance on conduct and reporting. DESIGN Systematic reviews focusing on safety were retrieved from NHS Evidence and searches of major databases. A pre-prepared template was used for data extraction. Information extracted included details of search strategies, sources, participants, interventions, reported adverse event/effect(s) and causality assessment. Data extraction was carried out by one researcher and a check for accuracy by a second researcher. Methods were assessed against criteria based on guidance provided by the Cochrane Adverse Effects Methods Group. RESULTS A total of 2563 citations were screened and 88 systematic reviews were selected for inclusion. The majority focused on the safety of herbs and nutritional supplements. Approximately half the reviews covered all aspects of safety; other reviews addressed specific adverse effects or interactions. Types of data included in the reviews did not always reflect the focus of the review. Search strategies, sources used, quality assessment and assessment of causality also varied. CONCLUSIONS Detailed examination and comparison of the methods has highlighted several areas in which there is potential for development of guidelines and consensus on standards. These include search strategies, sources of information, data extraction and assessment of causality. The value of systematic reviews in relation to large outcome studies requires further consideration.

Abstract
Acute and 90-day subchronic oral toxicity studies of Silk peptide E5K6 were performed in Sprague-Dawley rats. In the acute toxicity study, Silk peptide E5K6 was administered orally to male and female rats at a single dose of 2000 and 5000 mg/kg. Mortality, clinical signs and body weight changes were monitored for 14 days. There were no treatment-related changes in these parameters. Therefore, the Approximate Lethal Dose (ALD) of Silk peptide E5K6 in male and female rats is higher than 5000 mg/kg. In the subchronic toxicity study, Silk peptide E5K6 was administered orally to male and female rats for 90 days at a single dose of 500, 1000, and 2000 mg/kg. There were no toxicologically significant changes in clinical signs, body weight, food and water consumptions, ophthalmoscopic examination, urinalysis, hematological and serum biochemical examinations, necropsy findings, organ weights and histopathological examination of all of the animals treated with Silk peptide E5K6. These results suggest that the oral No Observed Adverse-Effect Level (NOAEL) of Silk peptide E5K6 is greater than 2000 mg/kg/day in both sexes and the target organs were not established.

Abstract
Traditional herbal substances may contain highly toxic chemicals and heavy metals, in addition to naturally occurring organic toxins. These substances may cause illness, exacerbate pre-existing ill health or result in death, particularly if taken in excess or in an unusual manner (e.g., injected rather than ingested). Lack of regulation of the content and quality of herbal medicines may result in contamination and adulteration with prescription medications. As there may be no history of the specific use of these products their contribution to death may not be fully appreciated during a standard autopsy. Even when their existence is known or suspected, it may be difficult to identify these substances on standard toxicologic screening. Herbal medicines may also be responsible for a range of symptoms and signs that may confuse the clinical presentation of cases. Given these issues the role of herbal medicines in forensic practice needs to be more clearly defined as deaths may be occurring where herbal medicines have made a significant, but as-yet unrecognized, contribution.
