Background
Star anise (Illicium verum) is an evergreen shrub or small tree native to Asia. It’s traditionally used as a spice in food, and also as medicine.
Star anise seeds contain chemicals that might have antibacterial effects. It also contains a chemical called shikimic acid, which is used to make oseltamivir (Tamiflu), a flu treatment. But it’s not clear if star anise itself has antiviral effects.
People use star anise for respiratory infections, stomach disorders, colic in babies, and many other conditions, but there is no good scientific evidence to support these uses.
In 2003, the US FDA warned consumers not to consume teas brewed from star anise due to reports of serious side effects. Some star anise tea products have been contaminated with Japanese star anise (Illicium anisatum), a known poison.
