Lippia: traditional uses, chemistry and pharmacology: a review

The chemical composition, pharmacological activity and traditional uses of 52 species attributed to the genus Lippia (Verbenaceae) as used in the South and Central America, and Tropical Africa, were revised and compared. A survey of the available literature shows that these species are used mostly for the treatment of gastrointestinal and respiratory disorders and as seasoning. Additionally, some of these Lippia species showed antimalarial, spasmolitic, sedative, hypotensive and, anti-inflammatory activities. Generally, the essential oil or the phenolic compounds (flavonoids) from these plant extracts are. assumed to be the active principles. (C) 2001 Elsevier Science Ireland Ltd. All rights reserved.
