Taro is grown for tubers as an important source of carbohydrates. However, these tubers contain itchy sap, so they must be cooked before consuming them. Tubers can be processed by steaming, boiling, baking, frying, or processed into flour, porridge, cakes, pasta and fermented to produce pudding.

Young leaves and stems are processed as vegetables in coconut milk. Leaves, stems and tubers are also used as animal feed and carp. The surface of the leaves is covered with fine hairs which make it waterproof, shield-shaped and wide often used as a head protector when it rains, food wrappers and live fish containers.

Taro has a sweet, spicy and neutral taste. Bulbs, leaves and petioles contain flour, villose, polyphenols and saponins. Tubers are used for anti-inflammation and reduce swelling. The leaves and stems are astringent.

Talas has at least four varieties. Pandanus taro has a purplish color, a reddish stem base and has a fragrance after boiling. Glutinous taro has a light green color, has a lot of shoots and is somewhat sticky after boiling. Bull taro has purple stems, large bulbs, but has a bitter taste.
