Finger root is a woody shrub that grows across West Africa. Its botanical name is Uvaria chamae. In Yoruba it is known as eruju.
The parts used are the root, the root bark and the stem bark. They are boiled into a bitter drink or ground into powder. The small orange fruits grow in finger-like clusters, which is where the English names come from.
Healers have used it for fever, loose stools, wounds and pain. Some people also chew the twigs as a tooth stick.
Here is the honest verdict. Nearly all the research sits in test tubes and in rats and mice. There are no good human trials, so what it does in people is simply not known.
Long use in a tradition is not proof that something works. It is also not proof that it is safe. Both of those apply here, and this page says so once rather than repeating it.
No mechanism has been confirmed in people. Everything below comes from the lab bench or from animals.
In test tubes, extracts of the root and bark slow the growth of some bacteria and fungi. Compounds called benzylated flavanones seem to drive much of this. Whether that happens inside the human body is unknown.
In mice infected with malaria parasites, some extracts lowered parasite counts. The drops were modest and far weaker than standard malaria drugs. No human study has tested this.
In rats, extracts reduced paw swelling in standard tests of inflammation. Researchers link this to the flavanones and triterpenes in the plant. Animal swelling tests do not predict relief of joint pain in people.
The bark is rich in tannins, which pull tissue tight. That astringent feel may explain why healers put it on wounds and used it for loose stools. It is a plausible idea, not a proven one.
One more gap matters. Nobody has shown that these compounds survive digestion and reach the blood in useful amounts.
Most use is of the raw plant, not a packaged product.
Common forms include:
- Dried root or bark pieces sold loose in West African markets - A decoction, meaning bark simmered in water and drunk - Twigs chewed as a tooth-cleaning stick - Dried powder, sometimes mixed into food or drink - Pastes and poultices put on wounds or sores - Bottled mixed herbal drinks (agbo) that list it among several plants - Capsules and tinctures sold online, mostly from small sellers
Two warnings about buying it. Mixed herbal bottles often hide what else is inside, including added painkillers in some reported cases. Capsules are rarely tested for strength or purity, so the label may not match the contents.
Uvaria chamae has a deep and well recorded place in West African herbal practice. Plant-use surveys in Nigeria, Ghana, Benin and Côte d'Ivoire record it again and again.
The Yoruba name is eruju. Healers reached for the root and bark for fevers thought to be malaria. They also used it for dysentery, piles, jaundice and sores.
Root preparations were applied to wounds to stop bleeding. The twigs served as tooth sticks for cleaning the mouth.
Some traditions used the root for delayed or painful periods. In parts of the region it was also used to bring on a miscarriage. That history is a serious reason for pregnant readers to stay away.
This section describes what was done in the past. It is a record, not advice to copy.
Stop taking it and see a doctor the same day if you notice:
- Yellow eyes or yellow skin (jaundice) - Dark urine, or passing much less urine than usual - Severe belly pain - Vomiting that will not stop - A spreading rash, or swelling of the face or lips
Get emergency help straight away for a fever with confusion, fits, severe breathlessness or a stiff neck. These can be signs of severe malaria or another serious infection.
Also see a doctor if a fever or diarrhoea is no better after 48 hours. Tell them exactly what you took, and bring the packet or plant with you.
In the United States it may be sold as a dietary supplement. It is not approved there to treat any illness.
In the UK and the EU there is no licensed herbal medicine made from it. In Nigeria and Ghana it is an ordinary market plant, and bottled herbal mixes containing it are sold widely.

The published evidence for Finger root (bush banana) is weak or absent. That usually means no controlled trial has tested it, not that a trial found it ineffective — the two are different, and we grade only what has been published.
What it is typically used for, usual dose, cautions, and the study behind it where real trial data exists.
