Track huacapurana with reminders and record whether it helped, in the app.
Huacapurana is the bark of an Amazon rainforest tree, Campsiandra angustifolia. Healers in Peru and Brazil have long used it as a bitter, drying bark tea. Today it is sold as bark chips, powder, capsules and tinctures.
It is marketed mainly for recovery after childbirth, for loose stools, and for washing wounds. Those are traditional uses. Long use in a tradition is not proof that something works, and it is not proof that it is safe.
Here is the plain verdict on evidence. We found no published trials of huacapurana in people. Everything below rests on custom, on lab work, and on what is known about tannin-rich barks in general.
Do not confuse it with huacapú (Minquartia guianensis). That is a different Amazon tree sold under a similar name.
Nobody has shown how huacapurana works in people, or that it works at all.
The bark is rich in tannins. These are plant compounds with a dry, puckering taste. In test tubes, tannins bind proteins and can tighten the surface of raw tissue.
That binding action is the usual reason bark teas have been used for loose stools and for washing sores. It is a chemical property of tannins, not a tested effect of this bark.
In laboratory tests, extracts of Campsiandra and related legume trees slow the growth of some bacteria and fungi. Whether that happens inside a human body is not established.
Sellers sometimes claim the bark lowers blood sugar, clears parasites or treats womb infections. Those claims rest on custom and on early lab work. No human study supports them.
Huacapurana is sold mostly by Amazon herb traders and online shops. Common forms are:
- Dried bark chips or shavings, boiled into a tea - Ground bark powder, loose or in capsules - Tinctures, usually in cane alcohol or rum - Mixed Amazon "tonic" blends, where it sits beside other barks
There is no standard strength. Two products with the same label weight can differ a lot. Few sellers test for identity, so the bark in a bag may not always be the right species.
Riverside and Indigenous communities of the Peruvian and Brazilian Amazon used huacapurana bark as a folk remedy. Written records of this date mainly from the twentieth century.
The bark was boiled in water, or steeped in cane spirit, and used after childbirth. It was also used for loose stools, for vaginal discharge, and as a wash for wounds and skin sores.
The tree grows in seasonally flooded forest, so bark was gathered in the dry months. These accounts describe custom. They are not instructions, and they do not tell you the practice was safe.
Stop taking it and see a doctor if you get belly pain, repeated vomiting, or a rash.
Get urgent medical help for any of these:
- Yellow skin or yellow eyes (jaundice), or dark urine - Blood in your stools, or black tarry stools - Diarrhoea with fever, or diarrhoea lasting more than two days - Swelling of the lips, tongue or throat, or trouble breathing - Any heavy bleeding, pain or fever after childbirth
Diarrhoea in a baby, a small child or an older adult needs a doctor quickly, whatever you have used for it.
In the United States it is sold as a dietary supplement, with no FDA review of its safety or claims. In the UK and the EU it is not an approved herbal medicine.

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