Therapeutic Potential of Colocasia esculenta in the Management of Oral Ulcers

Taro, Colocasia esculenta (L.) Schott, is a starchy tuberous crop eaten in many parts of the world and used in the folk medicine of several cultures. Its long ethnopharmacological record, especially in Asia, Africa and the Pacific Islands, has led researchers to look more closely at what the plant might offer therapeutically. This review summarizes the main features of C. esculenta, concentrating on its bioactive constituents and the pharmacological activities reported for them so far. Particular attention is paid to how the flavonoids, tannins and phenolic acids of the plant might act on the biological processes behind oral ulcer formation and healing. To support that discussion, the review draws together what is known about the botanical classification, morphology, traditional uses, chemistry and pharmacology of C. esculenta.
