African copaiba balsam is a sticky tree resin. It comes from Daniellia oliveri, a tall savanna tree. In Hausa the tree is called maje.
The tree grows across West and Central Africa. Cuts in the trunk weep a clear to amber balsam. Healers also used the bark, leaves and roots.
The resin was smeared on wounds and sore joints. Bark teas were drunk for fever, cough and stomach trouble. Long use in a tradition is not proof that something works, and it is not proof that it is safe.
Here is the honest verdict. Nearly all the research sits in test tubes and animals. No good human trials back any use of it.
Do not confuse it with South American copaiba. That balsam comes from Copaifera trees. The names overlap, but the plants do not.
Short answer: no one has shown how it works in people.
In lab dishes, the resin oil slows some bacteria and fungi. The effect is modest and changes with each batch. Whether it happens on human skin is untested.
Beta-caryophyllene is the main compound in the oil. In cell studies it binds a receptor tied to pain and swelling. That is a lab finding, not a proven effect in people.
In rodents, bark and leaf extracts eased pain and swelling in test models. Some rodent work also points to lower blood sugar and calmer behaviour. Animal results often do not carry over to humans.
The resin is thick and forms a seal on skin. That cover may help keep a small scrape clean. This is a simple physical effect, not proof of healing.
In West Africa, most people meet it as raw resin or dried bark.
- Raw balsam: the sticky sap tapped from the trunk.
- Dried bark: sold in pieces or ground, then boiled as a tea.
- Leaves and roots: boiled or crushed for local use.
- Essential oil: steam-distilled from the resin, sold for scent and massage.
- Incense and glue: the hardened resin burns well and sticks.
Outside Africa it is rare in shops. Online sellers mostly list the oil.
Plant identity is often unchecked. Some products labelled copaiba hold Copaifera resin instead.
Healers across the savanna belt treated maje as a everyday remedy tree. Records from Nigeria, Niger, Ghana and Mali all mention it.
The balsam was spread on wounds, boils and skin sores. Bark decoctions were drunk for fever, cough and loose stools. Leaf preparations were used for aches and for sleep.
The tree had non-medical uses too. The resin was burned as incense and used as glue. The timber was cut for carving and fuel.
Colonial-era trade notes called it an African copal or copaiba. That naming stuck in the oil trade. None of this history was tested in a modern trial.
Stop using it and see a doctor if you notice any of these:
- A rash, blisters or spreading redness where you applied it.
- Swelling of the face, lips or tongue, or trouble breathing; this is an emergency, so call for help.
- Yellow skin or eyes, dark urine, or pain under your right ribs.
- Unusual bruising, bleeding gums or nose bleeds.
- Vomiting that will not settle.
See a doctor straight away for fever with chills, a wound with pus or red streaks, or diarrhoea in a child. Do not wait on a home remedy for these.
No medicine agency has approved it as a treatment. In the UK, EU and United States it is not licensed as a drug.
It is sold mainly as a resin, essential oil or scent ingredient. In West Africa it is traded openly in markets as a herbal remedy.
