One cup/220 g of turmeric is a significant source of iron, potassium, and vitamin C, but, of course, it is never used in that quantity in a single dish, so its nutritional value is unimportant. It does have medicinal value in smaller amounts, however. In India, turmeric has been used in traditional Ayurvedic medicine as a remedy for poor digestion, to treat heart disease, and to heal wounds. The yellow compound found in the rhizome is curcumin, which has been the focus of several recent scientific studies into its anti-inflammatory and anticancer potential, based on its antioxidant strength.
