The first stage in assuring the quality, safety and efficacy of herbal medicines is identification of the plant species. Botanical verification is necessary. The information required includes the currently accepted Latin binomial name and synonyms, vernacular names, the parts of the plant used for each preparation, and detailed instructions for agricultural production and collection conditions according to the each country’s good agricultural practice. A WHO Consultation on Traditional Medicine and AIDS (September 1990) addressed the issues of quality control, safety and efficacy of herbal medicines. Detailed information is presented in Annex III. The WHO Quality control methods for medicinal plant materials1 and WHO monographs on selected medicinal plants2 can be consulted for quality control.
