When an ulcer or a wound is not treated, it gets infected and has lot of pus. Cut an unripe papaya. Scoop out the inside pulp and apply on the ulcer. Wash it off the next day and apply papaya pulp again. Continue till the ulcer becomes clean.
Ripe papayas are rich in vitamins and also aid digestion.
Eating them is especially helpful for weak and old people. The fruit contains chemicals that help soften and make dead flesh easier to remove. First clean and wash out a pressure sore that has dead flesh in it. Then soak a sterile cloth or gauze with 'milk' that comes out when the green fruit or trunk of the tree is cut, and pack this into the sore. Repeat cleaning and repacking 3 times a day.
