Fagara is the bark, root and twigs of a West African tree, Zanthoxylum zanthoxyloides. In Yoruba it is called orin ata, the "pepper stick". Twigs and roots are chewed to clean the teeth and ease toothache.
The taste is sharp and peppery. Chewing it makes the mouth tingle and go a little numb. That feeling is why it earned the name toothache bark.
Today it is also sold as dried root bark, powder and capsules. Much of that trade aims at people with sickle cell disease. Human evidence is thin for every use, and long traditional use is not proof that it works or that it is safe.
The mouth tingle is the clearest effect, and it is short-lived.
Lab work points to a few possible actions. In test tubes, extracts slow some mouth bacteria linked to plaque and decay. Whether that changes gum health on real teeth is not settled.
For sickle cell disease, test tube studies suggest some compounds help red blood cells keep their normal round shape. This is called an antisickling effect. It has not been confirmed in good human trials.
In animals, extracts have eased pain responses, relaxed blood vessels and lowered blood sugar. Animal results often do not carry over to people. Treat all of this as a lead, not a proven effect.
Fagara reaches buyers in several forms.
- Chewing sticks cut from twigs or roots, sold in West African markets and shops abroad. - Dried root or stem bark, loose or chopped. - Powders and capsules, often sold for sickle cell disease.
- Decoctions (drinks made by boiling the bark) and tinctures (alcohol extracts), made at home or by herbalists. - Mixed herbal products that combine fagara with other plants.
Labels rarely say how much alkaloid a product holds. Two packets with the same name can differ in strength.
Mixed products carry the risks of every other plant in them. Some are sold online with no checks on what is inside.
Fagara has been used across West Africa for centuries. Chewing sticks from the plant are an old daily habit in Yoruba, Igbo, Akan and Hausa homes.
Healers used the root for toothache, sore gums and mouth sores. Decoctions were given for fever, body pain, worms and sickle cell crises. Some traditions used the root to bring on labour, which is why pregnancy is now a clear reason to avoid it.
From the 1980s, researchers in Burkina Faso and nearby countries built herbal products from the plant for sickle cell disease. These stayed regional products. They were never tested to the standard a modern medicine must meet.
See a dentist within a few days for tooth pain that keeps coming back.
Get urgent care now if you have facial swelling, fever, or trouble swallowing or breathing. These can mean a spreading dental infection.
Stop fagara and call a doctor if you notice: - easy bruising, or gums that bleed more than usual - yellow skin or eyes, or dark urine - bad stomach pain or vomiting that will not stop - dizziness or fainting - a rash, swelling of the face, or wheezing
If you have sickle cell disease and get a pain crisis, chest pain or fever, go for urgent medical care. Do not treat it with herbs at home.
In the UK, the EU and the US, fagara is not approved as a medicine. It is traded as a herbal supplement or a chewing stick, often imported, with no official check on strength or purity. Some West African countries license regional herbal products made from the plant for local sale only.
