Normally found in the northeast of Brazil, Alpinia zerumbet (Pers.) B. L. Burtt. & R. M. Sm. is commonly known as "colônia". In folk medicine, it has been used as antihypertensive, diuretic and febrifuge. Some studies with essential oils have shown its antimicrobial and hypotensive activities, besides a slight diuretic effect. Aimed at improving the knowledge of such species, a survey of publications involving studies in pharmacological and chemical areas was conducted from 1987 to 2008.
