Betel nut is the seed of the fruit of the areca palm. The active ingredient in betel nut is arecoline. Betel nut is a stimulant, which means it speeds up the messages travelling between the brain and the body.
This plant grows in most of the tropical Pacific and Asia. It is also known as areca nut as well as regional names such as paan or supari (India and Pakistan), bin lang (China), puwak (Sri Lanka) and buia or daka (Papua New Guinea).
Betel nut plays an important role in social customs, religious practices and cultural rituals in several countries throughout the Asia-Pacific region. Betel nut is also used for recreational purposes and as mouth freshener and digestive aid after meals.
Around 10% of the world’s population (600 million people) chew betel nut in some form. Betel nut is the 4th most widely used psychoactive substance in the world, after nicotine, alcohol and caffeine. The number of people presenting with health issues associated with betel nut use is increasing in Australia.
How betel nut is used
Betel nut can be used on its own or as a mixture of various ingredients, known as 'betel quid'. The most common method of using betel nut is to slice it into thin strips and roll it in a betel leaf with slaked lime or crushed seashells. It is often mixed with tobacco and various spices.
Sometimes areca nuts are rolled in leaves other than betel leaf, such as a leaf from the rubiaceous plant (mitrogyna speciosa), nutmeg tree (myristica fragrans), or the pepper plant used in kava (piper methysticum).
Betel nut and the law
Up to 10kg of betel nuts may be imported into Australia, however additional biosecurity requirements apply.

Betel nut is listed as a prohibited plant under schedule 23 of the Australia New Zealand Food Standards Code, meaning it is prohibited from being sold as a food or being used as an ingredient in a food for sale.
