Medicinal uses

Star anise has been used in a tea as a traditional remedy for rheumatism, and the seeds are sometimes chewed after meals to aid digestion.As a warm and moving herb, star anise is used to assist in relieving cold-stagnation in the middle jiao, according to Traditional Chinese medicine.

Star anise is the major source of the chemical compound shikimic acid, a primary precursor in the pharmaceutical synthesis of anti-influenza drug oseltamivir (Tamiflu).[1] Shikimic acid is produced by most autotrophic organisms and whilst it can be obtained in commercial quantities from elsewhere, star anise remains the usual industrial source. In 2005, there was a temporary shortage of star anise due to its use in the production of Tamiflu. Late in that year, a way was found of making shikimic acid synthetically.[citation needed] Roche now derives some of the raw material it needs from the fermentation of E. coli bacteria. The 2009 swine flu outbreak led to another series of shortages as stocks of Tamiflu were built up around the world, sending prices soaring.[2]

Star anise is grown in four provinces in China and harvested between March and May. It is also found in the south of New South Wales. The shikimic acid is extracted from the seeds in a ten-stage manufacturing process which takes a year. Reports say[citation needed] 90% of the harvest is already used by the Swiss pharmaceutical manufacturer Roche in making Tamiflu, but other reports[citation needed] say there is an abundance of the spice in the main regions – Fujian, Guangdong, Guangxi and Yunnan.

Japanese star anise (Illicium anisatum), a similar tree, is not edible because it is highly toxic (due to containing sikimitoxin); instead, it has been burned as incense in Japan. Cases of illness, including “serious neurological effects, such as seizures”, reported after using star anise tea may be a result of using this species. Japanese star anise contains anisatin, which causes severe inflammation of the kidneys, urinary tract and digestive organs.The toxicity of Illicium anisatum, also known as Shikimi, is caused by its content in potent neurotoxins (anisatin, neoanisatin, and pseudoanisatin), due to their activity as non-competitive antagonists of GABA receptors.
