Plant
Star anise
Illicium verum
Also known as: Illicium verum, Chinese star anise
A small evergreen tree in the family Schisandraceae, native to southern China and northern Vietnam. The dried eight-pointed star-shaped fruit is one of the most distinctive-looking spices in any kitchen — and the source of shikimic acid, the precursor for industrial synthesis of the antiviral drug Tamiflu (oseltamivir). Foundational to Chinese five-spice powder, Vietnamese pho broth, Indian biryani, and broader East and Southeast Asian cooking. Closely related but DO NOT confuse with the Japanese star anise (*Illicium anisatum*), which is toxic — accidental contamination of imported star anise with the related toxic species has caused poisoning cases.
Scientific
Illicium verum is in Schisandraceae. The fruit is a follicle (a many-segmented dry fruit) with eight points — the distinctive star shape. The principal aromatic compound is anethole — the same compound that flavors anise and [[fennel]] (the three converge on the same primary aromatic despite being in three different plant families).
Star anise is also the principal industrial source of shikimic acid — the chemical precursor used in the synthesis of oseltamivir (Tamiflu), the antiviral drug used against influenza. The 2005–2006 H5N1 bird flu concern caused a temporary global shortage of star anise as pharmaceutical companies scaled up Tamiflu production. Synthetic and microbial routes to shikimic acid have since reduced this dependency.
Toxic relative
Illicium anisatum — Japanese star anise — looks visually similar but contains the neurotoxic compound anisatin. Japanese star anise was used historically as Buddhist incense but is dangerous if consumed. Contamination of imported Chinese star anise with Japanese star anise has caused multiple documented poisoning cases (including infants given star anise tea for colic, a folk practice that should be avoided).
Cultural
Chinese five-spice powder — star anise + Sichuan peppercorns + [[cinnamon]] + fennel + cloves — is the canonical Chinese spice blend, used across braised meats, roasts, and broths. Vietnamese phở broth is built on a long simmer with star anise, [[cinnamon|cinnamon]], cloves, cardamom, and beef bones; the spice profile is essential to the dish’s identity.
In Indian cooking, star anise (chakra phool) appears in some garam masala blends and biryani recipes — generally a North Indian / Mughlai influence rather than a pan-Indian one.
Global production
Top producers: China (Guangxi province dominates global supply), Vietnam, India, Japan, Philippines.
