Mucura is a herbal remedy made from Petiveria alliacea, a leafy plant of the American tropics. It is also called anamu or guinea hen weed. The root and leaves smell strongly of garlic.
In Latin American and Caribbean folk medicine it was used for aches, fevers, colds and "cleansing". Today it is sold as a tea, a capsule or a tincture.
Traditional use is not proof that a remedy works. It is also not proof that a remedy is safe. For mucura, nearly all research is in cells and animals, so its benefits in people stay unproven.
The plant carries real cautions. It can thin the blood, lower blood sugar, and it has a folk history as an abortifacient (something used to end a pregnancy).
No one has shown what mucura does inside the human body. The ideas below come from lab and animal work only.
In test tubes, its sulfur compounds slow the growth of some bacteria and fungi. Cell studies also report effects on cancer cell lines. Whether any of this happens in a person is not established.
In animals, extracts have lowered blood sugar and eased signs of pain and swelling. Lab work suggests effects on immune cells too.
These findings point researchers where to look. They are not proof of benefit, and they do not predict a dose for people.
Mucura is sold most often as dried root or leaf, and as capsules. Tinctures and liquid extracts are also easy to find.
- Dried root or leaf, brewed as a tea. - Capsules of milled powder. - Alcohol tinctures and liquid drops.
- Washes and poultices put on the skin in folk use. - Mixed "immune" or "detox" blends sold with other herbs.
None of these forms is standardised. Strength can differ widely between brands and between harvests.
Blends raise a second problem. You cannot tell how much mucura is in them, or what else the blend adds.
Mucura has a long record in the folk medicine of the Amazon, the Caribbean and Central America. Written accounts of its use go back centuries.
Healers used it for fevers, colds, aches, swollen joints and skin problems. Leaves were also boiled for washes and steam baths.
In parts of Afro-Caribbean practice the plant was used in spiritual baths and for warding off harm. Market sellers still stock it under the names anamu and guinea hen weed.
Some traditions used it to bring on a late period or to end a pregnancy. That history is a warning, not a recommendation. These accounts describe past practice, not a guide for use at home.
Stop taking mucura and get medical help the same day if you notice bruising with no cause, bleeding gums, nosebleeds, or blood in your urine.
Go to an emergency department now if you have black or tarry stools, vomit that looks like coffee grounds, or bleeding that will not stop.
Get urgent help if you feel shaky, sweaty and confused, which can mean very low blood sugar. The same goes for fainting, or swelling of the face, lips or throat.
If you are pregnant and have taken mucura, call your midwife or doctor straight away. Cramping or bleeding needs emergency care.
In the United States mucura is sold as a dietary supplement. It is not approved there as a medicine for any illness.
In the United Kingdom and the European Union it is not a licensed medicine. In several Latin American countries it is sold freely in markets and herb shops.

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