General Characteristics, Phytochemistry and Pharmacognosy of Lippia sidoides.

Lippia sidoides Cham. is a plant that belongs to the family Verbenaceac and is commonly known as "alecrim-pimenta". It was first found in northeastern Brazil, where it is extensively used in traditional medicine. Many studies have been made with the essential oil of L. sidoides, which has a high content of the isomeric compounds thymol and carvacrol. L. sidoides extracts, and particularly the essential oil extracted from its aerial parts, have shown many biological activities such as antifungal, antibacterial, and insecticidal. Given the great biological potentialities of L. sidoides and the amount of recent studies about this plant, the present study aimed to make a survey of its general attributes, cultivation methods, chemical characterization of its extracts and essential oil, as well as its different biological activities.
