Fagara is the bark, root and stem of Zanthoxylum zanthoxyloides, a spiny West African tree. In Yoruba it is called orin ata, the "pepper chewing stick". Cut pieces of the stem or root are sold for cleaning the teeth.
People also use it for toothache and gum trouble. In recent decades it has been promoted for sickle cell disease. The bark tastes hot and makes the mouth tingle and go numb.
Here is the honest verdict. Human evidence is thin, and most of it comes from small or poorly run studies. Long traditional use does not prove that a remedy works, and it does not prove that it is safe.
This page treats Fagara as a caution herb. Chewing sticks are used widely and seem mild. Strong root extracts are a different matter, and are covered in the safety section.
No one has shown how Fagara works in the human body. Nearly all the claims come from test tubes and animals.
In lab tests, extracts slow some mouth bacteria linked to plaque and gum disease. Whether this happens in a real mouth is not settled. Part of the cleaning effect of any chewing stick is simple scrubbing.
In lab work on blood samples, some of its acids stop red cells from taking on a sickle shape. That is a test tube finding. It has not been matched by clear results in patients.
The hot, tingling taste comes from pungent amides. These act on nerve endings in the mouth. They may dull pain for a short time, but they do not treat the tooth itself.
Some of its alkaloids block cell enzymes in lab studies. The same action is why strong root extracts raise safety questions.
The chewing stick is the main form: a cut piece of root or stem, chewed at one end until it frays.
Dried bark or root, sold loose or ground to powder.
Home-made teas and decoctions, boiled from the bark or root.
Capsules, powders and tinctures sold online as fagara, candlewood or artar root.
Toothpastes and mouth rinses that list the plant among the ingredients.
Mixed herbal products aimed at sickle cell disease, sold mainly in West and Central Africa.
Strength is not standardised anywhere. Two products with the same name can differ widely. Labels rarely state how much alkaloid is present.
Fagara has a long record in West African home and healer care, from Senegal to Nigeria and Cameroon. The root and stem were used for toothache, sore gums and daily mouth cleaning.
The Yoruba name orin ata points to the hot taste. Users prized the burn and the numb feeling it left behind.
Bark teas were also given in the past for fever, pain, worms and stomach upset. Some communities used the root to bring on labour. That is one reason pregnancy is a firm no today.
From the 1970s, researchers in West and Central Africa began testing the plant for sickle cell disease. That work still goes on. It has not yet produced strong proof in patients.
Stop using it and see a doctor if you get a rash, nausea that will not settle, bad belly pain, or dizziness.
Get urgent medical help for yellow eyes or skin (jaundice), dark urine, pale stools, or bleeding or bruising that is new to you.
Go to an emergency department for swelling of the lips, tongue or throat, or trouble breathing.
See a dentist the same day for facial swelling with a toothache, or a toothache with fever. That can mean a spreading infection.
If you have sickle cell disease, treat any crisis as a medical emergency and follow your care plan.
In the United States, United Kingdom and European Union, Fagara is not a licensed medicine. It is sold as a herbal supplement, a chewing stick or a cosmetic ingredient, with no official check on strength or purity. In parts of West and Central Africa, some fagara-based products are registered locally as traditional medicines.
