Illicium verum is a medium-sized evergreen tree native to northeast Vietnam and southwest China. A spice commonly called star anise, staranise, star anise seed, star aniseed, Chinese star anise, or badian that closely resembles anise in flavor is obtained from the star-shaped pericarps of the fruit of I. verum which are harvested just before ripening. Star anise oil is a highly fragrant oil used in cooking, perfumery, soaps, toothpastes, mouthwashes, and skin creams. 

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 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). If allowed to steep in coffee, it deepens and enriches the flavor. The pods can be used in this manner multiple times by the pot-full or cup, as the ease of extraction of the taste components increases with the permeation of hot water.

Star anise is the major source of the chemical compound shikimic acid, a primary precursor in the pharmaceutical synthesis of the anti-influenza drug oseltamivir (Tamiflu) and applied in the 2009 swine flu pandemic to address Tamiflu shortages, also causing price increases for star anise as a raw material of shikimic acid.
