What is Wild custard apple?

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.

How does Wild custard apple work?

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.

What forms does Wild custard apple come in?

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.

Where it comes from:

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.

What does Wild custard apple help with?

• Malaria and fever: Boiled bark and leaf drinks were a common fever remedy in the savanna. In mice with malaria, extracts cut parasite numbers. There are no human trials. Malaria can kill fast, so it needs tested drugs and a proper test for the parasite.
• Diarrhoea and dysentery (bloody diarrhoea): Healers gave bark drinks for loose stools. The bark holds a lot of tannins, which bind protein in the gut. That is chemistry, not a trial result. No human study has tested the plant for diarrhoea.
• Worms and other gut parasites: Root and bark were given for worms, including guinea worm. In lab dishes, extracts can kill some worms and water snails. No study in people supports this use. Worm infections have simple, proven treatments.
• Wounds, boils and skin infections: Leaf and bark pastes were put straight on sores and boils. In test tubes, extracts slow some bacteria and fungi. Whether that helps a wound on real skin is not known. A deep, hot or spreading wound needs medical care.
• Coughs and chest complaints: Bark drinks were used for coughs and chest pain. No trial in people has looked at this. Cough with fever, blood or breathlessness is a reason to see a doctor, not to self-treat.
• Stomach pain: Tradition used it for stomach ache and gut cramps. In rats, extracts reduced damage to the stomach lining. There is no human data at all. Pain that keeps coming back should be checked.
• High blood sugar: This is a modern research interest more than an old use. Rat studies report lower blood sugar after extracts. No human trial has tested it. If you take diabetes medicine, this plant could push your sugar too low.
• Fits and convulsions: Some healers used the plant for fits. In rodents, extracts delayed seizures brought on in the lab. That is a long way from treating epilepsy. Never swap a seizure medicine for a herb.
• Snakebite: Bark pastes were applied after snakebite in several regions. There is no evidence that this helps. Snakebite is an emergency. Go straight to hospital for antivenom.

Which foods are rich in Wild custard apple?

1. Ripe wild custard apple fruit (Annona senegalensis)

Practical Tips:

The fruit itself is the food form. It is picked wild and sold in local markets in season.

Related fruits share the same compound family. Soursop, sweetsop and cherimoya all belong to the Annona group.

Eating these fruits now and then is normal in many countries. Daily, heavy intake of Annona fruit, leaf tea or bark drinks is the pattern linked to nerve worries in research.

What are the side effects of Wild custard apple?

• Nausea and vomiting
• Stomach cramps
• Diarrhoea
• Burning or dryness in the mouth and throat from bitter bark
• Drowsiness or feeling dull
• Shaking, sweating or hunger from low blood sugar
• Skin rash where a paste was applied
• Eye pain and eye damage from seed material
• Possible nerve or liver harm with long, heavy use of bark or root

Good to know:

No proper safety study has been run in people. So the true rate of side effects is unknown.

What we have comes from healers, scattered case reports and animal work. Stomach upset is the complaint heard most often.

Seed material is the clearest hazard, above all to the eyes. The nerve concern from long bark use is serious but not yet measured in humans.

How much Wild custard apple should you take?

• Recommended daily: No safe or useful amount has been set for any medicinal use. This page gives no dose on purpose. Two reasons: - The strength of bark, root and leaf varies hugely between trees, seasons and batches. - The plant family makes acetogenins, which harm nerve cells in lab and animal studies. The ripe fruit is a different matter. It is eaten as an ordinary seasonal food in West Africa.
• Best time of day: Time of day has not been studied and is unlikely to matter. No schedule has evidence behind it.
• With or without food: Bitter bark and leaf drinks sit better on a full stomach. That is general advice, not a research finding. The fruit is simply a food. Eat it as you would any other fruit.
• Time to effect: There is no honest answer here. No trial has measured how fast it acts, or whether it acts at all. Traditional accounts describe relief from fever or cramps within a day. Those are stories, not measurements. It may well do nothing.
• How long to take it: No safe length of use is known. Repeated, long-term use of bark or root is the main worry. In the Annona family, long exposure to acetogenins has been linked to nerve damage in animals. Human data for this species is missing. Tradition describes short, one-off use for a passing illness. It does not describe taking it daily for months.
