Medicinal plants: an approach to rational and safe use

Abstract

Many plants are used for medicinal purposes, constituting therapeutic alternatives complementary to the medical treatment, bringing numerous health benefits, when used rationally and in an appropriate way. However, plants constitute a large arsenal of chemicals constituents, which may be beneficial, but may also pose a potential health risk. So, it is important that the user, the health professionals, and the prescribers, have knowledge about the plant, ensuring correct identification, conservation, preparation and use, as well as possible side effects. The study of the medicinal plants, their risks and benefits, and efficacy confirmation by carefully designed studies will be discussed in the light of contemporary scientific publications, paying attention to the contribution of health professionals in relation to their role as active educators and health promoters in communities, especially those users of the Unified Health System.
