Areca (Areca catechu) is a palm tree that grows up to 30 meters in height (Gruenwald et al. 1998 Robbers et al. 1996). It is cultivated in India, southeast Asia, the East Indies, and East Africa. It grows green leaflets and numerous flowers. The fruit of the areca palm is a nut that contains a single seed and a thin seed coat (figure 4.10). Areca is chewed alone or... 

The areca nut is sometimes erroneously referred to as the betel nut (Trivedy et al. 1999). Betel refers to a combined preparation of the areca nut (Areca catechu) and lime (calcium hydroxide), rolled into the leaf of the betel pepper (Piper betle) (Morton 1998). 

Areca (Areca catechu) is a tall palm tree that yields a nut, commonly chewed in Asia for its stimulant effects. It is discussed at greater length in chapter 4, but is mentioned here briefly for its cognitive effects. Areca s psychoactive constituents (arecoline, arecaidine, guvacoline, and guvacine) are agonists at muscarinic acetylcholine receptors. They also directly inhibit reuptake of GABA.

The choline ester, carbachol, activates M-cholinoceptors, but is not hydrolyzed by AChE. Carbachol can thus be effectively employed for local application to the eye (glaucoma) and systemic administration (bowel atonia, bladder ato-nia). The alkaloids, pilocarpine (from Pilocarpus jaborandi) and arecoline (from Areca catechu betel nut) also act as direct parasympathomimetics. As tertiary amines, they moreover exert central effects. The central effect of muscarinelike substances consists of an enlivening, mild stimulation that is probably the effect desired in betel chewing, a widespread habit in South Asia. Of this group, only pilocarpine enjoys therapeutic use, which is limited to local application to the eye in glaucoma...

The number of aberrant metaphases increased in cultures with 15 mL tobacco extract per milliliter of growth media Water extract of the dried leaf, administered to mice at a dose of 9.40 g/kg, 6 days a week for 10 months, was active on bone marrow. A combination of Piper betle, Areca catechu, and Nicotiana tabacum was used . Seed, administered orally to adults with oral cancer and oral submucosal fibrosis and to healthy chewers, was active. An average of 6 quids of tobacco leaf, Areca nuts, and lime were chewed daily T . ...

The nut of the palm Areca catechu contains a mildly stimulatory alkaloid and in some Asian countries the chewing of pieces of the nut is enjoyed because of the mild euphoric state it induces. Restrictions in the use of betel nut remain rather few despite some...
