African elemi is the sticky resin of Canarium schweinfurthii, a tall tree of West and Central Africa. People cut the bark and let the pale gum harden into lumps. It is burned as incense, used as a scent, and rubbed on the skin in folk practice.
The same tree gives a dark fruit known in Igbo as ube okpoko. The fruit is softened in warm water and eaten as a food. The fruit and the resin are not the same product and are not used the same way.
Human evidence that the resin treats anything is very thin. Most of what exists comes from test tubes and animals. Long use in tradition is not proof that it works, and it is not proof that it is safe.
No one has shown how this resin works in the human body.
The resin is rich in terpenes, the strong-smelling oils found in pine and citrus peel. In test-tube studies, these oils slow the growth of some bacteria and fungi. Whether the same thing happens on human skin has not been shown.
Lab work also reports that the oil mops up reactive molecules in a dish. That is a finding about a dish, not about a person.
Animal studies on bark and leaf extracts of Canarium species have looked at pain and swelling. The studies are small and early. They do not tell you what burning or rubbing the resin will do for you.
When the warm resin seems to soothe a sore joint, warmth, oil and massage may explain much of it.
You will most often meet it as hard lumps of raw resin sold for burning.
Common forms: - Raw resin lumps or tears, burned on charcoal - Steam-distilled essential oil, sold as elemi oil - Resin warmed into oil or fat for a skin salve - Powdered resin, blended into local preparations - The fruit, ube okpoko, eaten as a food after soaking
Quality varies widely. Market resin may carry bark, grit or soot. Oil sold online is not always from this tree.
The essential oil is strong and meant for scent or careful skin use. It is not a drink.
West African communities used this resin for centuries as incense, torch fuel and a sealing gum.
Igbo, Yoruba and other groups burned it in homes and at ceremonies. Healers spread the softened resin on boils, sores and aching joints. Smoke or steam from the gum was breathed in for chest and nose complaints.
The bark and wood had their own uses, and the fruit was an ordinary food. European traders later bought the gum as an elemi-type resin for varnish and perfume.
These are records of what people did. They are not records of benefit.
Stop using it and see a doctor if a rash spreads, blisters or does not settle within a few days.
Get medical help the same day if a sore becomes hot, swollen or oozing, or if you develop a fever.
Seek urgent care now if someone swallows the essential oil, or if you get wheeze, trouble breathing, a swollen face or lips, or a widespread hive-like rash.
In the UK, EU and United States this resin is sold as an incense and a perfume ingredient, not as a licensed medicine. No health claim for it is approved. In parts of West Africa the tree's fruit is an ordinary food, and the resin is traded freely in local markets.
