Pineapple Ananas comosus Bromeliaceae, the Bromeliad family Native to South America

Pineapple contains bromelain, which digests proteins and fights inflammation. Bromelain can help heal bruises and swelling, and it inhibits cancer. People often drink pineapple juice to relieve sports injuries and stomach problems. However, it is not clear how well that works because there is not very much bromelain in the fruit. Pineapple leaves may reduce blood lipids and blood sugar.
