Pharmacological actions and medicinal uses
Mango, the king of all fruits, has been shown to have many health benefits.
Mangoes could help facilitate healthy digestion. They are reported to contain enzymes that aid the breakdown and digestion of protein, and also fibre, which keeps the digestive tract working efficiently to induce a feeling of satiety. The phytochemicals in the mango skin act as natural fat busters. Thus, mangoes, when eaten in moderation, could also help in weight loss.

Studies in Japan and Mysore, respectively, proved that the extract of a mango peel has anti-diabetic properties with beneficial effects on type 2 diabetes patients. Mango leaves are reported to help regulate insulin levels. They also serve as stomach tonic.
The beta-carotene in mangoes help in the production of Vitamin A, the powerful antioxidant that helps improve vision and boosts overall eye health. According to a Boston study, mangoes contain a carotenoid called cryptoxanthin that was found to reduce the risk of age-related macular degeneration in elderly Japanese.
Mango has antioxidants which protect the body against breast, colon, prostate cancers and leukaemia. Mangiferin has also been found to inhibit the growth of colon and liver cancer cells and other tumour cells as well.
Mangoes have the ability to increase virility in men because of the vitamin E content. The fruit may aid menopausal and pregnant women because of its high iron and calcium levels.
In some parts of the Caribbean Islands, mango leaf decoction is used to treat diarrhoea.
Mangoes are also found to exhibit anti-ulcer activity, given the presence of tannins, flavonoids, and saponins.
