This root is known as “Peruvian ginseng” or “Peruvian viagra” The nutritional value of dried maca root is high, it is rich in calcium and potassium with a low sodium content, and contains essential oligo elements: iron, iodine, copper, manganese and zinc as well as fatty acids: Alpha-linoleic acid, palmitic acid and oleic acid, and 19 amino acids (Wikipedia).
