African star apple is the fruit of a West African tree, Chrysophyllum albidum. It is called agbalumo in Yoruba and udara in Igbo. The ripe fruit is orange, soft and sharply tangy, and is sold as a common street food.
Each fruit holds a few hard, flat seeds set in a star pattern. Healers have also used the bark, leaves and roots of the tree. Those parts are not food, and they are far less studied than the fruit.
As a food, the fruit is a useful source of vitamin C and fibre. As a remedy, the human evidence is very thin. Long use in tradition is not proof that something works, and it is not proof that it is safe.
No one has shown how African star apple acts in the human body. What follows is the proposed story, not a proven one.
The fruit carries vitamin C and plant antioxidants. Vitamin C does real work in people: it prevents and treats scurvy. The rest of the antioxidant claim rests on lab tests, where extracts mop up free radicals in a dish.
In rats, seed and bark extracts have lowered blood sugar and eased pain. In test tubes, bark and leaf extracts slow the growth of some bacteria and fungi. Whether any of that happens in a person is not established.
The ripe fruit also holds pectin, a soft fibre. Fibre of this kind draws water into the gut and can soften stool. That effect is general to fibre-rich fruit, and is not special to this one.
Most people meet it as plain fresh fruit, eaten by hand.
Common forms include:
- Fresh ripe fruit, sold in season in West African markets - Juice, jam, candy and ice cream made from the pulp - Dried fruit powder, sold online as a supplement - Bark or root decoctions, used by traditional healers - Seed kernel oil, used in soap and skin products
The fruit and the bark are not the same thing. Most safety reports and most nutrient data cover the fruit only. Bark and root preparations have no agreed strength and little study of any kind.
African star apple has been eaten and used across West Africa for centuries, well before any written record of it.
In Nigeria, Ghana, Côte d'Ivoire and Cameroon the fruit marked the dry season and was shared widely. Among the Igbo it is udara, and it carries meaning in folklore and family stories. Among the Yoruba it is agbalumo, a market staple.
Healers used the bark for fever and malaria-like illness, the leaves for wounds and skin sores, and the seeds for pain. The fruit itself was used for sore throat and cough. These were household and healer practices, recorded later by ethnobotanists.
That record tells us what people did. It does not tell us whether it helped, and this page does not suggest copying it.
Get emergency care the same day if someone swallows a seed and then has belly pain, vomiting, a swollen belly, or passes no stool or gas. That can mean a blocked bowel.
See a doctor if a sore throat comes with high fever, drooling or trouble swallowing. See a doctor for any fever you think might be malaria, and go at once.
Stop using it and get checked if you get a rash, mouth swelling or trouble breathing after eating it.
In Nigeria, Ghana and across West Africa it is an ordinary food, sold freely in markets. In the UK, EU and United States it is treated as a food or a food supplement, not as a medicine. No regulator has approved it to treat any condition, and supplement powders are not checked for strength or purity.
