The purpose of this review is to provide an overview of most recent studies about potential pharmaceutical applications of plants belonging to Origanum genus. Oregano is one of the most famous and economically important culinary herbs in the world. The genus Origanum includes more than 70 species mainly distributed around the Mediterranean region. The vernacular name “oregano” is attributed to a vast number of species. O. vulgare L. is the most variable species of the genus and the most commonly known as oregano in most countries. Today, it is generally accepted that oregano is a characteristic flavour produced by a number of plant species that yield carvacrol-rich essential oils. The genus Origanum is characterised by a large morphological and chemical diversity. Because of their several biological activities, such as antimicrobial, expectorant, antispasmodic and carminative, Origanum species have been used in traditional medicine to treat various diseases. The botany and chemotaxonomy of the species are thoroughly reported, along with chemical constituents. The in vitro and in vivo effects of Origanum extracts are presented and discussed.
