Balanites aegyptiaca is the desert date, a thorny tree of dry Africa, the Middle East and South Asia. Its yellow date-like fruit is eaten as food in the Sahel. The bark, seeds, leaves and kernel oil have long been used in African folk medicine.
People have used it for blood sugar, worms, skin sores, jaundice and fevers. Crushed seed has also been thrown into ponds to kill the water snails that spread bilharzia. That last use is for water, not for people to swallow.
Here is the honest verdict. Human evidence is thin and low in quality. Most findings come from test tubes and animals.
Long use in tradition is not proof that it works. It is also not proof that it is safe. The fruit pulp is an ordinary food, but concentrated bark and seed preparations are a different matter.
No mechanism for this plant has been confirmed in people. What follows comes from lab and animal work.
The seeds, bark and root are rich in saponins. These are soapy plant chemicals that foam in water. In test tubes they break open cells, which is why crushed seed kills water snails and fish.
In animal studies, fruit and seed extracts have lowered blood sugar. Researchers think the saponins and a related compound, diosgenin, may be involved. Whether this happens in people, at a safe amount, is not known.
In lab tests, extracts slow some worms, bacteria and fungi. These tests use direct contact with strong extracts. That is a long way from what reaches your gut or skin.
The kernel oil is high in oleic and linoleic acid. On skin it acts as a simple softening oil. That part is straightforward and does not need a special mechanism.
Most of what is sold outside Africa is either the oil or a dried powder.
- Whole or dried fruit (often called lalob or hidjlij), eaten as food or soaked into a drink. - Kernel oil, sometimes sold as betu or zachun oil, used on skin and hair and in cooking. - Bark or root decoctions, made by boiling in water, used in village medicine.
- Powdered leaf, bark or seed, sold loose or in capsules. - Crushed seed cake used in ponds and canals to kill snails, which is not a human remedy. - Soap and cosmetic products made from the oil.
Labelling is often poor. Many products do not say which part of the plant is inside.
The desert date has been used across Africa for thousands of years. Seeds and fruit have been found in ancient Egyptian tombs.
In the Sahel and Sudan the fruit was a famine food and a village staple. Healers in West and East Africa used bark and root for fevers, worms, jaundice and skin sores. The oil was rubbed on dry skin and wounds.
The tree also appears in Indian texts under the name ingudi. It was linked there with skin complaints and with worms.
In the twentieth century, health workers studied the crushed seed as a cheap way to kill the snails that carry bilharzia in standing water. That work was about the water supply, not about treating sick people.
None of this history tells you how the plant behaves in a modern body alongside modern medicines.
Stop and see a doctor if you get vomiting, bad stomach pain or ongoing diarrhoea.
Get urgent care for yellow skin or eyes, dark urine, or passing much less urine than usual. These can point to liver or kidney trouble.
Get urgent care for shaking, sweating, confusion or fainting, which can mean low blood sugar.
Call emergency services for a fast or pounding heartbeat, a swollen face or lips, or trouble breathing.
In the UK, US, EU and Australia it is not approved as a medicine for any condition. The fruit is eaten as a food in parts of Africa and Asia, and the oil turns up in cosmetics. Supplements are sold without checks on strength or purity.
