Star anise is a fruit of a small oriental tree grown almost exclusively in China and Japan although it is native to Vietnam also. The star shaped fruits are harvested before it ripens and then dried and used as a spice.
Star anise can be found in Asian supermarkets. When buying star anise look for whole pieces that aren't damaged or broken. If stored in an airtight container star anise will keep for a year or more.
FDA Quote
Japanese star anise in its dried or processed form cannot be distinguished from Chinese star anise through visual examination. Therefore, FDA is evaluating chemical analytical methods that will differentiate between the two species of star anise. Until FDA is able to differentiate between Japanese and Chinese star anise, it is advising the public not to consume "tea" brewed from any star anise. As part of its ongoing efforts to protect consumers from unsafe products, FDA will monitor imports of star anise entering the United States from various countries to ensure that any imports of Japanese star anise are not labeled or otherwise indicated for use as a food. — FDA
