Betelnut
Betel-nut, the seed of Areca Catechu, a palm cultivated in tropical Asia. It resembles a nutmeg in size, in colour, and in its "ruminate" albumen which gives it a mottled appearance internally. Pieces of this nut are rolled up with a little lime in leaves of Piper Betel, the Betel-pepper, and chewed by the natives. The pellet is hot, acrid, aromatic, and astringent, tinges the saliva red, and stains the teeth.
