Illicium anisatum, with common names Japanese star anise,aniseed tree, and sacred anise tree, known in Japan as shikimi (樒, シキミ), is a tree closely related to the Chinese star anise. Since it is highly toxic, the fruit is not edible; instead, the dried and powdered leaves are burned as incense in Japan. Cases of illness, including serious neurological effects such as seizures, that have been reported after using star anise tea may be a result of using this species instead of Chinese star anise (Illicium verum).
I. anisatum is native to Japan. It is similar to I. verum, but its fruit is smaller and with weaker odor, which is said to be more similar to cardamom than to anise. While it is poisonous and therefore unsuitable for using internally, it is used for treatment of some skin problems in traditional Chinese medicine.
Japanese star anise contains anisatin, shikimin, and sikimitoxin, which cause severe inflammation of the kidneys, urinary tract, and digestive organs. Other compounds present in toxic species of Illicium are safrole and eugenol, which are not present in I. verum and are used to identify its adulteration. Shikimi gave its name to shikimic acid, a substance also present in the plant.
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.
Illicium comes from the Latin illicio meaning "entice". In Persian, star anise is called بادیان bādiyān, hence its French name badiane. In India, it is called badian or phoolchakri and in Pakistan, it is called badian.
Star anise contains anethole, the same ingredient that gives the unrelated anise its flavor. Recently, star anise has come into use in the West as a less expensive substitute for anise in baking, as well as in liquor production, most distinctively in the production of the liquor Galliano. It is also used in the production of sambuca, pastis, and many types of absinthe. Star anise enhances the flavour of meat. It is used as a spice in preparation of biryani and masala chai all over the Indian subcontinent. It is widely used in Chinese cuisine, and in Indian cuisine where it is a major component of garam masala, and in Malay and Indonesian cuisines. It is widely grown for commercial use in China, India, and most other countries in Asia. Star anise is an ingredient of the traditional five-spice powder of Chinese cooking. It is also a major ingredient in the making of phở, a Vietnamese noodle soup.It is also used in the French recipe of mulled wine : called vin chaud (hot wine).
