Overview

Betel nut is the nut that comes from a plant called Areca. It is sometimes used to make medicine. Betel nut is chewed alone or in the form of quids, a mixture of tobacco, powdered or sliced betel nut, and other ingredients.

Betel nut is used for schizophrenia, a group of eye disorders that can lead to vision loss (glaucoma), poor digestion, and many other conditions, but there is no good scientific evidence to support these uses. Using betel nut might also be unsafe.

Some people use betel nut as a recreational drug because it speeds up the central nervous system (CNS).

How does it work ?

Betel nut seems to affect certain chemicals in the brain and other parts of the central nervous system.

Uses & Effectiveness ?

Insufficient Evidence for

  • Schizophrenia. Early research suggests that chewing betel nut might reduce symptoms in some people with schizophrenia. But using betel nut for a long time can be unsafe.
  • Stroke. Early research suggests that taking a solution containing betel nut extract might improve speech, strength, and bladder function in people who have had a stroke.
  • Glaucoma.
  • Aiding in digestion.
  • Other conditions.
More evidence is needed to rate the effectiveness of betel nut for these uses.

Side Effects

When taken by mouth: There isn't enough reliable information to know if betel nut is safe to take in small doses or for a short time. But betel nut is LIKELY UNSAFE when taken long-term or in high doses. Using betel nut has been associated with many difference cancers. Other chemicals in betel nut are poisonous. Eating 8-30 grams of betel nut can cause death.

Chewing betel nut can make your mouth, lips, and stool turn red. It can cause stimulant effects similar to caffeine and tobacco use. It can also cause more severe effects including vomiting, diarrhea, gum problems, increased saliva, kidney disease, liver disease, heart disease, chest pain, abnormal heart beat, low blood pressure, shortness of breath and rapid breathing, heart attack, coma, and death.

It can also cause more severe effects including vomiting, diarrhea, gum problems, increased saliva, kidney disease, liver disease, heart disease, chest pain, abnormal heart beat, low blood pressure, shortness of breath and rapid breathing, heart attack, coma, and death. It's LIKELY UNSAFE for anyone to take betel nut by mouth for more than a short time. But betel nut is especially dangerous for people with the following conditions:

Pregnancy and breast-feeding: Taking betel nut by mouth is LIKELY UNSAFE. Betel nut can affect the central nervous system and this might endanger a pregnancy. Chemicals in betel nut might pass into breast milk and harm a nursing infant. Stay on the safe side and avoid using betel nut if you are pregnant or breast-feeding.

Asthma: Betel nut might make asthma worse.

Slow heart rate (bradycardia): Betel nut might slow down the heart beat. This could be a problem in people who already have a slow heart rate.

Heart disease: People with heart disease might have an increased risk of having a heart attack if they use betel nut. If you have heart disease, do not use betel nut.

Gastrointestinal tract blockage: Betel nut might cause "congestion" in the intestines. This might cause problems in people who have a blockage in their intestines.

Stomach ulcers: Betel nut might increase secretions in the stomach and intestines. There is concern that this could worsen ulcers.

Lung conditions: Betel nut might increase fluid secretions in the lung. There is concern that this could worsen lung conditions, such as asthma or emphysema.

Seizures: There is concern that betel nut might increase the risk of seizures.

Urinary tract obstruction: Betel nut might increase secretions in the urinary tract. There is concern that this could worsen urinary obstruction.

Interactions ?

    Moderate Interaction

    Be cautious with this combination

  • Drying medications (Anticholinergic drugs) interacts with BETEL NUT

    Betel nut contains chemicals that can affect the brain and heart. Some drying medications can also affect the brain and heart. But betel nut works differently than drying medications. Betel nut might decrease the effects of drying medications.

    Some of these drying medications include atropine, scopolamine, and some medications used for allergies (antihistamines), and for depression (antidepressants).

  • Various medications used for glaucoma, Alzheimer disease, and other conditions (Cholinergic drugs) interacts with BETEL NUT

    Betel nut contains a chemical that affects the body. This chemical is similar to some medications used for glaucoma, Alzheimer disease, and other conditions. Taking betel nut with these medications might increase the chance of side effects.

    Some of these medications used for glaucoma, Alzheimer disease, and other conditions include pilocarpine (Pilocar and others), donepezil (Aricept), tacrine (Cognex), and others.

  • Medications for depression (MAOIs) interacts with BETEL NUT

    Betel nut might increase the amount of a chemical in the brain. This chemical is called serotonin. Some medications used for depression also increase serotonin. Taking betel nut with these medications used for depression might cause there to be too much serotonin. This could cause serious side effects including heart problems, shivering, and anxiety.

    Some of these medications used for depression include phenelzine (Nardil), tranylcypromine (Parnate), and others.

  • Doxorubicin (Adriamycin, others) interacts with BETEL NUT

    There is some concern that betel nut might cause mouth sores in people being treated with doxorubicin for cancer. Until more is known, avoid betel nut if you are being treated with doxorubicin.

Dosing

The appropriate dose of betel nut depends on several factors such as the user's age, health, and several other conditions. At this time there is not enough scientific information to determine an appropriate range of doses for betel nut. Keep in mind that natural products are not always necessarily safe and dosages can be important. Be sure to follow relevant directions on product labels and consult your pharmacist or physician or other healthcare professional before using.
