Papaya leaf extract and fruit anti cancer benefit by Ray Sahelian, M.D.

The papaya fruit is used in The Gambia at the Royal Victoria Hospital, Banjul in the Pediatric Unit as a component of burns dressings. The pulp of the papaya fruit is mashed and applied daily to full thickness and infected burns. It appears to be effective in loosening necrotic tissue, preventing burn wound infection, and providing a granulating wound suitable for the application of a split thickness skin graft. Possible mechanisms of action include the activity of proteolytic enzymes chymopapain and papain, as well as an antimicrobial activity
