Jatobá is a tall tree from the warm forests of Latin America. Folk healers used its inner bark, its hard sap and its fruit. Today it is sold mostly as a bark powder, capsule or tea.
The fruit pulp is dry, sweet and starchy, and it smells strong. That smell is why people call it stinking toe. Another old name is West Indian locust.
Human research on jatobá is very thin. Almost all of the support for it comes from long folk use and from lab work. Traditional use is not proof that a remedy works, and it is not proof that it is safe.
The short verdict: the fruit is an ordinary food, but the medicine claims made for the bark are not backed by good human trials.
No one has shown how jatobá works in the body of a living person.
The bark is rich in tannins. These are plant compounds that taste dry and bind to proteins. In test tubes, tannins can tighten tissue and slow the growth of some germs.
That is the usual reason given for the old use in loose stools and mouth rinses. Whether it does anything once swallowed is not known.
In lab dishes, jatobá extracts appear to slow enzymes that break starch into sugar. Some animal work hints at lower blood sugar. This has not been tested properly in people, so treat it as an idea, not a finding.
Cell and animal studies also report lower markers of swelling and damage from free radicals. Free radicals are unstable particles made as the body burns fuel. Again, these results come from dishes and rodents.
The sticky resin holds aromatic oils. In lab tests some of these slow certain bacteria and fungi. Whether that happens on human skin or in the gut is not established.
Jatobá is sold in a few simple forms.
- Dried inner bark, loose or cut, for making a tea or decoction - Bark powder in capsules or tablets - Liquid extracts and tinctures in alcohol - Fruit pulp or jatobá flour, used in breads, porridge and drinks - Raw resin, sold as incense or as a craft varnish
The fruit flour is a food and is treated as one. Bark products are the ones sold with health claims.
Quality varies a lot. Bark is often wild-harvested, and labels rarely state how much of any compound is inside. Resin sold for incense or varnish is not a food product and should not be eaten.
Jatobá has a long standing in Latin American folk medicine, going back well before written records.
In Brazil and the Amazon, healers brewed the inner bark into a bitter tea. It was given as a tonic for tiredness, and for coughs and chest complaints. Bark teas were also used for stomach upset and bladder trouble.
In the Caribbean the tree was known as West Indian locust, and the fruit was eaten as a filling snack and famine food.
The resin had its own uses. People burned it as incense, used it as a glue and varnish, and applied it to the skin in some regions.
These uses tell you what people believed and relied on. They were recorded by travellers, herbalists and local healers, not tested in trials.
Stop taking jatobá and see a doctor if you get a rash, itching or swelling.
Get urgent help for swelling of the lips, tongue or throat, or for trouble breathing. These are signs of a severe allergic reaction.
See a doctor promptly if you notice yellow skin or yellow eyes, dark urine, or pain under the right ribs.
If you take diabetes medicine, watch for shaking, sweating, confusion or a pounding heart. Those can mean low blood sugar.
Do not keep treating these yourself: a cough lasting over three weeks, blood in your spit or urine, a fever with back pain, or stools that stay loose for more than a few days.
In the United States and the United Kingdom, jatobá is sold as a food supplement, not as a licensed medicine. No health claims for it have been approved by regulators. In Brazil and nearby countries, the fruit is an ordinary food.

Reviewed by the HealisticMD editorial team How we grade evidence →
The published evidence for jatobá 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.
