The areca tree is a feathery palm that grows to approximately 1.5 m in height and is widely cultivated in tropical India, Bangladesh, Japan, Sri Lanka, south China, the East Indies, the Philippines, and parts of Africa. The tropical palm trees bear fruit all year. The nut may be used fresh, dried, or cured by boiling, baking, or roasting. The quid is a mixture of areca nut, tobacco, and lime wrapped in the leaf of the betel vine (Piper betel L. Family: Piperaceae).
What is it used for?
Traditional/Ethnobotanical uses
The chewing of betel nut quids dates to antiquity. In the 1st century AD, Sanskrit medical writings claimed that betel nut possessed 13 qualities found in the region of heaven. It is pungent, bitter, spicy, sweet, salty, and astringent. It was said to expel wind, kill worms, remove phlegm, subdue bad odors, beautify the mouth, induce purification, and kindle passion. Because of its CNS stimulating effects, betel nut is used in a manner similar to the western use of tobacco or caffeine. Arecoline is responsible for some of the effects of betel quid chewing, such as alertness, increased stamina, a sense of well-being, euphoria, and salivation. Chewing the nut stimulates the flow of saliva to aid digestion. Betel nut also has been used to stimulate the appetite.
Miscellaneous uses
Betel nut's medical use is limited, and long-term negative reactions to betel quid chewing are well known. A decrease in positive symptoms among men with schizophrenia was attributed to betel nut consumption.
Documented adverse reactions, including DNA damage and damage to the fetus. Avoid use.
Interactions
None well documented.
Side Effects
Betel nut consumption has been linked to the incidence of metabolic syndrome.
Toxicities
Areca nut and the betel leaf have caused DNA damage and cancer in cells and in animal experiments. There is a dose- and duration-dependent association of betel quid chewing with precancerous changes in the mouth as well as mouth, throat, laryngeal, and esophageal cancer.

Betel nut is a combination of three ingredients. People roll small pieces of the nut from Areca catechu, more commonly called betel palm, in a leaf from the Piper betel vine, then add powdered slaked lime or limestone paste, and chew it. The substance is popular in certain parts of the world, primarily Asia and Africa, as a recreational drug due to its psychoactive and stimulant effects. Some components of betel nut have pharmacological properties, but little evidence supports its use for any therapeutic purpose, according to the U.S. National Institutes of Health. Additionally, betel nut use can worsen high or low blood pressure and irregular heart rate, as well as asthma. Chronic use may increase the risk of certain cancers. The NIH notes that toxic effects of betel nut may outweigh any possible benefits.
Stroke Recovery
Betel nut extract may be beneficial for stroke recovery, according to InteliHealth. Improvements have been noted in speech, bladder control and muscle strength in patients taking betel nut extract, although InteliHealth explains that studies so far have been small and flawed.
Schizophrenia
Preliminary research indicates improvements in symptoms for schizophrenia patients who take betel nut, according to the NIH. Standard schizophrenia medications produce unpleasant side effects, fueling further efforts to discover new treatments, but the NIH notes that betel nut also produced side effects of tremors and stiffness in the schizophrenia research.
Cavity Prevention
Betel nut may have antibacterial effects, and it previously was included as a toothpaste ingredient for preventing cavities, according to InteliHealth. Because of its toxic effects, however, betel nut is likely less useful than other therapeutic agents for dental purposes.
Dry Mouth Relief
People who chew betel nut tend to produce large amounts of saliva, according to InteliHealth. This could help people with dry mouth caused by health conditions such as diabetes and Sjogren's syndrome. InteliHealth explains that safer medications are available to relieve this symptom.
