Pineapple is the common name of Ananas comosus. Medicinal properties of pineapple areattributed to bromelain - crude aqueous extract from stem and fruit of pineapple. Bromelain belongs to a group of protein digesting enzymes. Several studies have been carried out indicating that bromelain has useful phytomedical application. Bromelain can be absorbed in human intestines without degradation and without losing its biological activity. Due to a wide range of health benefits bromelain can be used for prevention of different ailments, such as digestive and cardiovascular diseases, cancer, diabetes, joint issues and muscle soreness.

Pineapple has been used as a medicinal plant in several native cultures before bromelain was discovered. It was an important part of tribal medicine, used in wound healing, as an anti-inflammatory and digestive aid.
Pineapple is native to South America. It is cultivated in several tropical and subtropical regions.
