Bromelain

Bromelain is an extract derived from the stems of pineapples, although it exists in all parts of the fresh plant and fruit, which has many uses. The extract has a history of folk and modern medicinal use. As a supplement it is thought to have anti-inflammatory effects. Bromelain also contains chemicals that, according to laboratory research, might interfere with the growth of tumor cells and slow blood clotting. As a culinary ingredient it is used primarily as a tenderizer.
