Abstract

The use of herbal medicines has increased remarkably in line with the global trend of people returning to natural therapies. Herbal formulations have reached widespread acceptability as therapeutic agents for diabetics, arthritics, liver diseases, cough remedies, memory enhancers and adoptogens. Herbal medicine products are dietary supplements that people take to improve their health and are sold as tablets, capsules, powders, tea, extracts, fresh and dried plants. Though herbals are traditionally considered to be harmless, some may cause health problems, some are not effective or some may react with other drugs. Hence standardization of herbal formulations is essential in order to assess the quality of drugs based on the concentration of their active principles.
