OBJECTIVE: This study aimed to determine the knowledge, attitudes and practices (KAP) of a selected population of patients on herbal dietary supplements (HDS).
METHOD: Methodological triangulation was used to generate a conceptual framework on HDS KAP. A survey of 175 patients was performed to measure knowledge and attitudes regarding HDS and SPSS was used for data analysis. Inverviews and focus group discussions (FGDs) were conducted to further explore the attitudes and practices, and constant comparison method was used for analysis of responses.
RESULTS: Respondents were generally aware of HDS. Majority of survey respondents believed that HDS are different from conventional drugs (52.0%, p<0.05). However, knowledge on the role of the Food and Drug Administration (FDA) in regulating HDS and understanding of "No Approved Therapeutic Claims" were poor.
The attitude toward HDS was generally positive. Majority (64.0%, p<0.05) were positive toward their perceived health benefits as claimed for the prevention of diseases, while a smaller percentage (46.9%, p<0.05) believed in their benefit for the treatment of diseases. A favorable attitude regardings HDS safety was observed due to the idea of their being "herbal" and "natural".
Among the survey respondents, only 22% were HDS users. Family was shown to promote use while cost deterred their use.
CONCLUSION: Individual knowledge and attitudes on HDS exert significant influence toward HDS practices. Factors that promote use are poor knowledge and positive attitudes toward HDS. Good knowledge seems to lead to judicious use or non-use.

Background: Consumption and abuse of alcohol remains a significant cause of concern worldwide. Furthermore, there is evidence of the association between chronic alcohol use and reduced life expectancy. Objectives: To study the effects of Garcinia binucao extract (GBE) supplementation on lifespan of Drosophila melanogaster, in the presence or absence of chronic alcohol exposure. Methods: D. melanogaster was mass cultured and given GBE supplementation in high (1 mg/mL) and low (200 µg/mL) sublethal doses. D. melanogaster flies were divided into groups - with and without chronic alcohol exposure, and their respective lifespans were monitored. Results: In D. melanogaster without alcohol exposure, mean lifespan was highest in the control flies (38.15 days), followed by high-dose GBE (34.42 days), low-dose GBE (33.24 days), and DMSO (22.29 days). In D. melanogaster chronically exposed to alcohol, the longest mean lifespan was observed in flies treated with high-dose GBE (33.80 days), followed by low-dose GBE (33.63 days), the DMSO group (30.30), and the control group (29.65 days), but the differences were not statistically significant. Comparing groups with and without chronic alcohol exposure, the mean lifespan of the control group chronically exposed to alcohol significantly decreased by 9.51 days (p < 0.05). In GBE treatment groups, mean lifespan significantly decreased by 0.82 days in high-dose set-up (p < 0.05), and significantly increased by 0.39 days in the low-dose set-up (p < 0.05) upon chronic alcohol exposure. Conclusion Garcinia binucao extract supplementation ameliorated the observed reduction in lifespan of Drosophila melanogaster chronically exposed to alcohol.
