Several aspects of Zingiber zerumbet: a review

ABSTRACT

Abstract Zingiber zerumbet (L.) Roscoe ex Sm., Zingiberaceae, is a perennial, aromatic and tuberose plant that grows in humid locations. Also known as bitter ginger, Z. zerumbet is traditionally found throughout Asia, where it is widely used in foods, beverages and for ornamental purposes. The viscous juice present in the inflorescence of the plant is rich in surfactants and is also known as "ginger shampoo". The rhizome can be macerated in ethanol and used as a tonic and a stimulant. In Brazil Z. zerumbet is found in the Amazon region, in Taruma-mirim and Puraquequara (rural areas of Manaus, Amazon, Brazil). The main chemical compounds found in Z. zerumbet are terpenes and polyphenols. Zerumbone, a sesquiterpene, is the principal bioactive compound of Z. zerumbet and it is widely studied for its medicinal properties. The extracts and isolated metabolites of Z. zerumbet have exhibited the following properties anti-inflammatory, antioxidant, antidiabetic, anticancer, antimicrobial, analgesic and antiviral. The National Institute of Amazon Research in Brazil is currently conducting studies using extracts from this plant to obtain compounds active in tumor models. The aim of this review is to provide a overview about the main aspects related with pharmacognosy and pharmacology of Z. zerumbet published in the literature over the last decade.
