Wild custard apple is a small tree or shrub of the West African savanna. Its botanical name is Annona senegalensis. In Hausa it is called gwandar daji.
The sweet orange fruit is picked and eaten as food. The root, stem bark and leaves are used in West African herbal practice. They are boiled in water, dried and powdered, or pounded into a paste.
Here is the short verdict. Human evidence is almost absent. Nearly all research is test tube or rat work.
Long and wide traditional use is not proof that it works. It is also not proof that it is safe. This page says so once, and does not repeat it in every section.
No one has shown how this plant acts in the human body. The ideas below come from lab dishes and animals.
In test tubes, leaf and bark extracts slow the growth of some bacteria and fungi. In mice given malaria, extracts lowered parasite counts. These are early signals, not proof of an effect in people.
In rats, extracts have lowered blood sugar and reduced swelling. Other rodent work points to a calming effect on the brain and delayed fits. Whether any of this happens in a person is unknown.
The Annona family also makes compounds called acetogenins. In lab and animal studies, these block part of the energy system inside cells. That is one reason the long-term safety of strong bark and root drinks is in doubt.
Most people meet this plant as fresh fruit or as raw dried plant material. It is rarely a packaged product.
Common forms: - Ripe fruit, eaten fresh in season - Dried root or stem bark, boiled into a decoction (a boiled water drink) - Dried leaves, used as a tea or a skin wash - Powdered bark or leaf, stirred into water or food - Pastes and poultices laid on the skin - Seeds, used in some places to kill insects or fish
Seeds and seed oil are not food. Keep them out of the eyes and off broken skin.
A few online sellers offer capsules and tinctures. In most countries these are not tested for strength or purity.
Healers across West and Central Africa have used this tree for centuries. It appears in Hausa, Yoruba, Fulani and many other local practices.
Recorded uses included fevers and malaria, loose stools, worms and chest complaints. Bark and leaf washes were laid on sores, boils and snakebites. Some communities used it in care after childbirth.
The fruit was, and still is, gathered as a wild food in the dry savanna. Village markets sell it when it ripens.
Stop and get medical help if you notice any of these:
- Vomiting that will not stop, or bad stomach pain - Yellow skin or yellow eyes (jaundice, a sign of liver trouble) - Shaking, sweating or confusion that eases after you eat (low blood sugar) - New tremor, stiffness or trouble walking - Dark urine, or passing much less urine than usual
Go to an emergency department now if you have swelling of the lips or face, a tight throat or trouble breathing. Do the same for eye pain after any contact with the seeds.
Fever that does not settle, a spreading wound or a snakebite all need a doctor the same day.
The fruit is an ordinary food in West Africa and is sold in local markets. No country licenses the plant as a medicine. In the UK, US and EU, any product sold would be an unchecked herbal supplement, not approved to treat disease.

Reviewed by the HealisticMD editorial team How we grade evidence →
The published evidence for Wild custard apple 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.
