Mozote is a common roadside weed used as a folk remedy across Latin America. Its botanical name is Bidens pilosa. In English it is often called beggar's tick, and in Spanish aceitilla, amor seco or picão preto.
The plant belongs to the daisy family. The leaves and flowering tops are dried and brewed as a tea. In some regions the young shoots are boiled and eaten as a green vegetable.
People take it most often as a tea for blood sugar, stomach upset or wounds. The tradition behind it is old and wide.
But long use only shows that a plant is familiar. It does not show that the plant is safe, or that it works.
Here is the short verdict. Lab and animal work looks interesting, especially for blood sugar. Good human evidence is missing, so no benefit in people can be claimed.
No one has shown clearly how Mozote acts in people. The ideas below come from lab dishes and animals, not from patients.
In diabetic mice, a compound called cytopiloyne appears to lower blood sugar. It seems to act on the insulin-making cells of the pancreas. Whether that happens in a human body is not known.
In cell studies, extracts appear to calm inflammation signals. In test tubes, extracts slow the growth of some bacteria and parasites. These are early signals, not proof of benefit.
Some traditional uses assume the tea acts as a water pill (diuretic). Animal work gives partial support for this. It has not been measured properly in people.
Most people meet Mozote as a loose dried herb for tea. Other forms are sold too.
- Dried leaf and flowering top, brewed as a tea or infusion. - Tinctures, which are alcohol extracts in dropper bottles. - Capsules and tablets of powdered herb or extract.
- Fresh crushed leaf, used in folk practice as a poultice on skin. - Washes and gargles made from cooled tea. - Fresh young leaves, cooked and eaten as a vegetable in some countries.
The plant grows as a weed in many places. Picking it yourself carries real risk. Roadsides and farm edges may carry traffic grime, weedkiller or animal waste.
Healers in Mexico, Central America and the Andes used Mozote for centuries. Written records date from the colonial period. Earlier Indigenous use is likely but hard to date exactly.
Traditional uses included washing wounds, easing stomach complaints and bringing down fever. In the twentieth century the tea became popular for "sugar", meaning diabetes. Similar uses were recorded in Africa and Asia, where the same plant grows.
It also served as food in lean seasons. Young shoots were boiled and eaten with maize or beans. None of this history is a reason to treat yourself.
Stop taking it and see a doctor if any of the following happen:
- A rash, hives, swelling of the lips or face, or trouble breathing. Breathing trouble means call emergency services now. - Yellowing of the skin or eyes, dark urine, or pain under your right ribs. - Shaking, sweating, confusion or a pounding heart, which can mean low blood sugar. - Vomiting or diarrhoea that lasts more than a day. - Passing much less urine than usual.
Also see a doctor if the problem you are treating is not better in two weeks. A fever after travel to a malaria area needs same-day care.
In the United States, Mozote is sold as a dietary supplement, not an approved medicine. In the United Kingdom and the European Union it is sold as a food or herbal product, and is not a licensed medicine. In parts of Latin America and Africa it is also an ordinary food plant.
