Pharmacological effects of different chemotypes of Lippia alba (Mill.) N.E. Brown

Abstract

The Lippia alba species consists of an aromatic plant used in Brazilian traditional medical practice and in the medical practice of several countries as well. Presenting a wide variability in its essential oil chemical composition, the Lippia alba is classified in chemotypes, or chemical races, according to the major constituents contained in its essential oil. Considering the quali and quantitative distribution of the components in the essential oil affect directly its pharmacological properties, which are presented in the medicinal species, this paper proposes a scientific literature review to correlate both biological and pharmacological properties presented by L. alba according to its chemical constitution.
