It also contains soluble fiber and pectin to help lower cholesterol levels. Quercetin—which is a powerful antioxidant for boosting immunity is found in the santol fruit. It acts as a natural precursor to cortisone, containing natural steroidal sapogenin and alkaloids that help treat skin diseases like psoriasis. It can also be used for treating fungal infections, and helps to lower bacterial count of the oral cavity, helping to prevent tooth decay. Studies show that Santol reduces the number and size of mammary tumors in rats.
