The swollen underground stems are used for food and animal fodder, and the roots and leaves are used medicinally in some countries. For example, in Hawaii, it has been used to treat digestive complaints, as a topical dressing for burns, and as a love charm. In the Philippines, the leaf stalks have been used to relieve toothache and on Java the roots and leaves have been used to relieve pain and redness. The rhizomes contain an anti-fungal protein called alocasin.
