Preliminary studies indicate that certain compounds in the mango skin have potential to lower risk of diseases, such as diabetes, high cholesterol levels or some forms of cancer.
The mango triterpene, lupeol, is an effective inhibitor in laboratory models of prostate and skin cancers. An extract of mango branch bark called Vimang, isolated by Cuban scientists, contains numerous polyphenols with antioxidant properties in vitroand on blood parameters of elderly humans.
The pigment euxanthin, known as Indian yellow, is often thought to be produced from the urine of cattle fed mango leaves; the practice is described as having been outlawed in 1908 due to malnutrition of the cows and possible urushiol poisoning. This supposed origin of euxanthin appears to rely on a single, anecdotal source, and Indian legal records do not outlaw such a practice.
