Notes: There once may have been more than 200 Hawaiian varieties of ‘uala. In old Hawai‘i, the young leaves were eaten as greens (called palula), and the sap was used in many medicinal treatments. A nursing mother wore an open lei of ‘uala vines to induce the flow of milk. The tuberous root (a great source of vitamin A, calcium and phosphorus) was an important food for early Hawaiians; and continues to be a local favorite today.
