During the past decade, traditional systems of medicine have become a topic of global importance. Current estimates suggest that, in many developing countries, a large proportion of the population relies heavily on traditional practitioners and medicinal plants to meet primary health care needs. At the same time, many people in developed countries have begun to turn to alternative or complementary therapies, including medicinal herbs.

Safety and efficacy data are available for even fewer plants, their extracts and active ingredients, and the preparations containing them. Assurance of the safety, quality, and efficacy of medicinal plants and herbal products has now become a key issue in industrialized and in developing countries.
