Areca nut | Mild High but Long Term Health Problems

Areca nuts, also known as betel nuts, are fruits produced on the Areca palm tree (Areca catechu). The nuts are treated like chewing tobacco and are chewed for a mild sedative and relaxing effect.

Although the effects are similar to tobacco, the plants don’t contain any nicotine. They contain a different compound that has been linked to some alarming health conditions.

What are the active compounds in Areca nut?

The main compound found with Areca nuts is arecoline. It’s a mildly addictive alkaloid that’s often likened to nicotine as they produce similar effects. When chewed, Areca nuts can produce a mild high and an increase in energy and even memory retention.

Arecoline is however an extremely toxic alkaloid and it’s been linked to many harmful cancers and diseases.

What effect does Areca nut have on the body?

Like nicotine, arecoline has been widely studied. Long-term use has been linked to cancers of the mouth and esophagus. It can also cause long-term respiratory problems and cancers within other areas of the body. 

There’s also a risk of diabetes and chronic kidney disease, as areca nut affects blood sugar and arecoline is processed in the kidneys. Overall it’s considered a very unsafe plant to chew or consume.

Long-term users will often develop a red mouth and lips due to an oily residue found inside. After chewing on areca nuts and leaves, this residue is spat out.

Does Areca nut have medical benefits?

Studies have shown that arecoline does have several small benefits. Within one scientific study, it was shown to improve the cognitive abilities of participants. This led to scientists exploring the possibility of arecoline as a drug to treat Alzheimer’s.

It has also been shown to reduce depression because of its stimulating and relaxation effects. However, scientists generally conclude that the carcinogenic effects outweigh any positive benefits.
