Betel nut: Betel nuts come from the areca tree, a tropical palm tree. Betel nut use refers to a combination of three ingredients: the nut of the betel palm (Areca catechu), part of the Piper betel vine, and lime. Preliminary evidence suggests that betel nut may act as a stimulant. It is believed that small doses can lead to stimulant and euphoric effects, and betel nut chewing is popular due to these effects. Although all three ingredients may contribute to stimulant properties, most experts believe that chemicals in the betel nuts (alkaloids) may be responsible. Other substances that may be combined with betel nut chew, such as tobacco, may also contribute to its purported effects. However, chronic use of betel nuts may increase the risk of some cancers, and immediate effects can include worsening of asthma, high or low blood pressure, and abnormal heart rate.Based on the known toxicities of betel nut use, the risks may outweigh any potential benefits.
