Product Code Database
Illicium verum ( star anise or badian, Chinese star anise, star anise seed, star aniseed and star of anise) is a medium-sized evergreen tree native to South China and northeast Vietnam. Its star-shaped harvested just before ripening are a spice that closely resembles anise in flavor. Its primary production country is China, followed by Vietnam and other Southeast Asian countries. Star anise oil is highly fragrant, used in cooking, perfumery, soaps, toothpastes, mouthwashes, and skin creams. Until 2012, when they switched to using biotechnology E. coli, Roche Pharmaceuticals used up to 90% of the world's annual star anise crop to produce oseltamivir (Tamiflu) via shikimic acid.
Verum means "true" or "genuine".
The name "badian" appears to derive, via French badiane, from the apparently descriptive Chinese language name for it, 八角, p=bājiǎo, lit. "eight horns". However, a derivation from the Persian language بادیان]] , "fennel", exists, with the Oxford English Dictionary indicating that its origin before that is unknown."badian, n."

The fruit is a capsule-like follicetum, star-shaped, reddish-brown, consisting of six to eight follicles arranged in a whorl. Each follicle is boat-shaped, 1–2 cm long, rough and rigid, color reddish-brown, with 1 seed, opening along the ventral edge when ripe. carpels size of 10 mm long, boat-shaped; they are hard and wrinkled, containing one seed. Seeds are brown, compressed ovoid, smooth, shiny and brittle with approximate size of 8–9 mm × 6 mm.
Differences with similar taxa:
Illicium anisatum had smaller fruits that does not form a regular star due to the abortion of some carpels. Also fruit follicles are not swollen in the middle and had a more pointed apex. Also usually had more than 8 follicles and the fruit has weaker odour. The seeds in Illicium anisatum are flat or almost spherical.
It is used as a spice in preparation of biryani and masala chai in some parts of the Indian subcontinent. It is widely used in Chinese cuisine, 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, Mulled wine (hot wine). If allowed to steep in coffee, it deepens and enriches the flavor. The pods can be used in this manner multiple times by the potful or cup, as the ease of extraction of the taste components increases with the permeation of hot water.
Japanese star anise ( Illicium anisatum), a similar tree, is highly toxic and inedible; in Japan, it has instead been burned as incense. Cases of illness, including "serious neurological effects, such as seizures", reported after using star anise tea may be a result of deliberate economically motivated adulteration with this species. Japanese star anise contains the neurotoxin anisatin, which also causes severe inflammation of the kidneys (nephritis), urinary tract, and digestive organs when ingested.
Swamp star anise Illicium parviflorum, a similar tree found in the southern United States, is highly toxic and should not be used for folk remedies or as a cooking ingredient.
Use
Culinary use
Star anise contains anethole, the same compound that gives anise, an unrelated plant, its flavor. Star anise has come into use in the Western world as a less expensive substitute for anise in baking, as well as in liquor production, most distinctively in the production of the liqueur Galliano. Star anise enhances the flavor of meat.
Drug precursor
Star anise is the major source of the chemical compound shikimic acid, a primary precursor in the drug synthesis of the anti-influenza drug oseltamivir (Tamiflu). An industrial method for the production of shikimic acid using fermentation of E. coli bacteria was discovered in 2005, and applied in the 2009 swine flu pandemic to address Tamiflu shortages, eventually reversing price increases for star anise as a raw material of shikimic acid. As of 2018, fermentation of E. coli was the manufacturing process of choice to produce shikimic acid for synthesis of Tamiflu.
Toxicity of related species
Illicium verum is not toxic. However, other related species are toxic.
