Fulltext Adverse effects of herbal or dietary supplements in G6PD deficiency: a systematic review

Lee SW, Lai NM, Chaiyakunapruk N, Chong DW

Br J Clin Pharmacol, 2017 01;83(1):172-179.
PMID: 27081765 DOI: 10.1111/bcp.12976

AIM: Glucose-6-phosphate dehydrogenase (G6PD) deficiency is a common genetic disorder, affecting nearly 400 million individuals worldwide. Whilst it is known that a number of drugs, foods and chemicals can trigger haemolysis in G6PD deficient individuals, the association between herbal and dietary supplements and haemolysis is less clear. The objective of this study was to evaluate the association between herbal or dietary supplements and adverse events in G6PD deficient individuals.
METHODS: We searched 14 electronic databases from their inception until November 2015 for articles describing the use of herbal or dietary supplements in G6PD deficient individuals. Additional publications were identified from manually searching textbooks, conference abstracts and the grey literature. All study designs were included as long as they contained clinical information. These gathered findings were summarized narratively.
RESULTS: Thirty-two publications met inclusion criteria. These reported on 10 herbal and dietary supplements. Overall evidence linking haemolysis to a herbal/dietary supplement was only found for henna. No evidence of harm was observed for vitamin C, vitamin E, vitamin K, Gingko biloba and α-lipoic acid.
CONCLUSIONS: The review showed that there was insufficient evidence to contravene the use of most herbal or dietary products at therapeutic doses in G6PD deficient subjects.

Fulltext Mitragyna speciosa use in the northern states of Malaysia: a cross-sectional study

Ahmad K, Aziz Z

J Ethnopharmacol, 2012 May 7;141(1):446-50.
PMID: 22440259 DOI: 10.1016/j.jep.2012.03.009

ETHNOPHARMACOLOGICAL RELEVANCE:
The consumption of Mitragyna speciosa (MS) for its psychoactive effects is widely reported amongst people in the villages in Thailand and Malaysia even though its use is illegal.
AIM OF THE STUDY: This study examined the pattern of MS use, its reported effects and explored its potential to cause dependence.
MATERIALS AND METHODS: We used both convenience and snowball-sampling methods to recruit participants in a border town between two northern states in Malaysia. Face-to-face interviews were conducted with the use of a structured questionnaire on 562 respondents who gave oral consent to participate in the study.
RESULTS: The response rate was 91%. The majority of the respondents (88%) reported daily use of MS. The main mode of using MS was by drinking the MS extract as tea (90%). The mean age of starting MS use was 28.3 (SD=8.1) years. A variety of reasons were given for using MS including for social and recreational needs, stamina and physical endurance, pain relief and improved sexual performance. Despite its reported usefulness in weaning off opiate addiction, 460 (87%) admitted they were not able to stop using MS. Only education level had a statistically significant association with the ability to stop or not stop the use of MS (χ(2)=31.0, df=1, p<0.001). Significantly higher proportions of those with a lower education level (38%) were able to stop using MS compared to respondents with a higher education level.
CONCLUSIONS: Our study provides important information on the pattern of MS use, its effects and its potential to cause addiction, as there has been growing interest in MS as evidenced by the number of advertisements for its sale on the Internet. Future study is required to explore its psychological and social impact on users.

Fulltext Study on the potential toxicity of a thymoquinone-rich fraction nanoemulsion in Sprague Dawley rats

Tubesha Z, Imam MU, Mahmud R, Ismail M

Molecules, 2013 Jun 26;18(7):7460-72.
PMID: 23803717 DOI: 10.3390/molecules18077460

Toxicological studies constitute an essential part of the effort in developing an herbal medicine into a drug product. A newly developed thymoquinone-rich fraction nanoemulsion (TQRFNE) has been prepared using a high pressure homogenizer. The purpose of this study was to investigate the potential acute toxicity of this nanoemulsion in Sprague Dawley rats. The acute toxicity studies were conducted as per the OECD guidelines 425, allowing for the use of test dose limit of 20 mL TQRFNE (containing 44.5 mg TQ)/kg. TQRFNE and distilled water (DW) as a control were administered orally to both sexes of rats on Day 0 and observed for 14 days. All the animals appeared normal, and healthy throughout the study. There was no observed mortality or any signs of toxicity during the experimental period. The effects of the TQRFNE and DW groups on general behavior, body weight, food and water consumption, relative organ weight, hematology, histopathology, and clinical biochemistry were measured. All the parameters measured were unaffected as compared to the control (DW) group. The administration of 20 mL TQRFNE /kg was not toxic after an acute exposure.
