Vettila is an evergreen and perennial creeper, with glossy heart-shaped leaves, producing woody stems 5-20 m long. The stems produce adventitious roots, with which they can adhere to other plants etc for support. Leaves are light green to bright green, glossy, deeply veined and hairless. They are heart-shaped with entire leaf margin. Leaf stalk is reddish like the stem. The primary use of betel leaf is as a wrap for chewing of betel nut or tobacco where it is mainly used to add flavour.
Betel vine is native to India and SE Asia. The leaves, roots and seeds are all used for medicinal purposes in Asia. Leaf preparations and the leaf sap are applied to wounds, ulcers, boils and bruises.
