Flowering Period : Throughout the year

Uses : Fruits edible, tender leaves edible. Seed (nut) is aromatic and astringent, and can be addictive. It is used against anaemia, fits, leucoderma, leprosy, and obesity, and is also a purgative and an ointment for nasal ulcers. In India, the nut has been used to treat tapeworms. Chewing on the seeds (nuts) produces euphoria, heightened alertness, sweating, salivation, and an increased capacity to work, and alkaloid arecoline, which is found in the nut, accounts for these effects. Tannins, which are found in betel nut, were traditionally being used for dyeing clothes.
