Areca catechu

Areca catechu is a tropical palm cultivated for its seed, commonly called areca nut or betel nut. The seed is widely chewed, often with betel leaf and slaked lime, despite established health risks.

Areca nut: The seed of Areca catechu, chewed in many regions alone or in mixtures that often include betel leaf and lime. This palm is cultivated chiefly for the seed consumed in chewing traditions.
Arecaceae: The palm family, a diverse group of flowering plants found mainly in tropical and subtropical regions. Areca catechu belongs to this family of palms.
Biogeography of palms: The study of where palm species occur and how their distributions arose. The palm’s native range and spread are questions of palm biogeography.
Oral submucous fibrosis: A chronic, progressive disorder that stiffens the tissues lining the mouth and restricts opening. Areca nut chewing is a leading cause of this disabling oral condition.
Betel quid: A preparation commonly combining areca nut, betel leaf, and slaked lime, sometimes with tobacco or other ingredients. The palm’s seed is a principal ingredient in this widely used preparation.
Areca: A genus of palms native to tropical Asia and the Pacific, including Areca catechu. The species is one member of this broader palm genus.
Indo-Malaya: A biogeographic region spanning South and Southeast Asia and parts of the Malay Archipelago. This region lies within the native-range debate and early history of areca cultivation.
Oral potentially malignant disorders: Oral tissue changes associated with an increased risk of developing cancer. Habitual chewing can cause oral lesions that may progress toward malignancy.
Areca nut production in India: The cultivation and harvesting of areca palm seeds in India, the world's largest producer. India illustrates the crop’s large-scale agricultural and economic importance.
Monocotyledon: A flowering plant whose seed typically has one embryonic seed leaf. Areca catechu is a monocot, a major lineage of flowering plants.
