Illicium verum is a medium-sized native evergreen tree of northeast Vietnam and southwest China. A spice commonly called star anise, star anise seed, Chinese star anise or badiam that closely resembles anise in flavor is obtained from the star-shaped pericarp of the fruit of Illicium velum 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.
