Illicium verum is a medium-sized evergreen tree native to northeast Vietnam and southwest China. A spice commonly called star anise, staranise, star anise seed, Chinese star anise, or badian that closely resembles anise in flavor is obtained from the star-shaped pericarpsof the fruit of I. verum which are harvested just before ripening. Star anise oil is a highly fragrant oil used in cooking, perfumery, soaps, toothpastes, mouthwashes, and skin creams. About 90% of the world's star anise crop is used for extraction of shikimic acid, a chemical intermediate used in the synthesis of oseltamivir (Tamiflu).
