Western Herbalism Properties
Botanical Description
Areca catechu is a slender, solitary, evergreen palm in the Arecaceae, probably native to the Philippines or insular Southeast Asia and now cultivated throughout tropical Asia, parts of East Africa and the western Pacific for its widely chewed seed, the betel or areca nut. Trees reach 15-25 m tall, with a straight, smooth, greenish to grey trunk 10-20 cm in diameter, conspicuously ringed by the scars of fallen leaf bases. A graceful crown of six to twelve large pinnate leaves up to 2 m long emerges from a smooth green crownshaft at the top of the trunk, each leaf with numerous closely set, linear, glossy green leaflets. Branched inflorescences emerge from below the crownshaft, bearing many small, fragrant, creamy-white male flowers above a few larger basal female flowers. The fruits are ovoid orange-yellow to scarlet drupes 5-7 cm long, each containing a single hard, reddish-brown seed.
