Elephant foot yam (scientifically known as Amorphophallus paeoniifolius) is a tropical perennial vegetable native to Southeast Asia. It is valued for its underground corm, which serves as a staple food across many regions due to its nutritional richness. The corms of elephant foot yam are not only rich in vitamins A, phosphorus, and calcium but also possess medicinal properties. They are used in traditional medicine to treat various ailments, including asthma, piles, and dysentery.
