Pawpaw is the papaya tree, Carica papaya. In Ghana it is called borɔferɛ in Twi. Home remedies use the leaf, the root and the seed, not only the sweet fruit.
The leaf is brewed as a bitter green tea or pressed for juice. The black seeds are chewed or dried and ground. The root is boiled into a strong decoction.
In West African homes these parts were used for fever, malaria, worms, poor digestion and wounds. The root also had a second, risky use: ending a pregnancy. That history matters, because it is the clearest warning the plant carries.
Here is the honest verdict. Papaya leaf is the only part with real human trials, mostly in dengue fever, and those trials are small and mixed. The seed and the root have almost no human evidence at all.
Long use in a tradition is not proof that a remedy works. It is also not proof that it is safe. Both of those apply here, and they apply most strongly to the root.
Ripe papaya fruit is a normal food and is not the subject of this page.
The short answer is that nobody has shown clearly how papaya leaf acts in the body.
The most studied idea comes from dengue research. In a small trial, papaya leaf juice was linked to faster recovery of platelets, the cells that help blood clot. The authors also saw changes in two genes tied to platelet production, but that is a hint, not a settled mechanism.
In test tubes, papaya leaf extract slows some bacteria and some malaria parasites. Whether that happens inside a person who drinks the tea has not been shown.
In animal studies, leaf extract lowered blood sugar and reduced swelling. Animal results often fail to repeat in people, so treat these as leads only.
Papaya seed and unripe fruit latex contain papain, an enzyme that breaks down protein. Papain digests protein in a dish, which is why green papaya tenderises meat. That is a kitchen fact, not evidence that it digests food better inside you.
In animal work, seed extract lowered sperm counts, and the effect faded after the animals stopped. In laboratory and animal studies, papaya latex also made the womb contract. This is the most likely reason the root and unripe fruit were used to end pregnancy, and it is why the pregnancy warning on this page is absolute.
You will meet pawpaw remedies in several forms.
Fresh leaf juice. Young leaves are pounded and squeezed. This is the form used in most dengue trials.
Leaf tea. Dried or fresh leaves are steeped in hot water. This is the common home form in West Africa.
Standardised leaf extract tablets, capsules and syrups. These are sold as supplements in many countries. In India one such tablet is sold as a licensed medicine.
Dried leaf powder. Sold loose or in capsules.
Seeds. Eaten raw, or dried and ground like pepper.
Root decoction. Boiled root, used in traditional practice. It is rarely sold commercially and carries the highest risk on this page.
Papain on its own. Sold as a digestive enzyme supplement and as meat tenderiser.
Latex from the unripe fruit. Used in tradition on skin and warts. It is irritating and should not be swallowed.
Papaya came from Central America and reached West Africa through Portuguese trade in the 1500s. It spread fast and became a village tree across Ghana, Nigeria and the wider region.
In Twi-speaking Ghana the tree is borɔferɛ. Healers brewed the leaf for fever, for what was called malaria, and for weakness after illness. The bitter taste was taken as a sign of strength.
Seeds were chewed for intestinal worms, often by children, and were also used for stomach upset. Crushed leaves were laid on sores and slow-healing wounds.
The root held a more guarded place. It was boiled for urinary trouble, and it was known as a way to end an early pregnancy. That second use was never casual knowledge; it was handled by specific practitioners.
Similar uses grew up in India, the Caribbean and Southeast Asia. The dengue use is modern and mostly Asian, dating from the last few decades.
None of this history tells you what works. It tells you what people reached for, and what they already treated as dangerous.
Stop and get medical help straight away if you have:
Swelling of the lips, tongue or throat, a spreading rash, or trouble breathing. These are signs of a serious allergic reaction. Call emergency services.
Bleeding gums, blood in your urine or stool, or bruises that appear for no reason.
Vaginal bleeding or cramping during pregnancy, or after taking any pawpaw remedy while pregnant. Go to hospital.
A fever that lasts more than two days, especially with a rash, severe headache or pain behind the eyes. Dengue and malaria both need testing.
Shaking, sweating or confusion if you take diabetes medicine. Check your blood sugar.
A heartbeat that feels very slow, or fainting.
See a doctor sooner rather than later if nausea, stomach pain or diarrhoea does not settle after you stop.
Papaya fruit is an ordinary food everywhere. In the United States, the United Kingdom and the European Union, papaya leaf products are sold as food supplements and are not approved to treat any disease. In India, a standardised papaya leaf extract tablet has been approved for sale as a medicine for dengue.
