Huitlacoche is rich in potassium, which reduces blood pressure and protects against stroke, osteoporosis, and kidney stones.
Corn smut (español: huitlacoche) is a plant disease caused by the pathogenic fungus Ustilago maydis that causes smut on maize and teosinte. The fungus forms galls on all above-ground parts of corn species. It is edible, and is known in Mexico as the delicacy huitlacoche, usually served in soups or as a filling in tacos and other tortilla-based foods. It has been called Mexican truffle and Aztec caviar.
