Flor de manita is the dried flower of the devil's hand tree, Chiranthodendron pentadactylon. The tree grows in the mountain forests of southern Mexico and Guatemala. Its deep red flower curls into the shape of a small hand, which gives it its name.
In Latin American folk medicine the dried flower was brewed as a tea. People drank it for a racing or fluttering heartbeat, for nerves, for poor sleep and for loose stools. It is still sold loose in Mexican markets and in mixed "heart and nerve" tea blends.
Here is the honest verdict. Controlled human trials of flor de manita are close to non-existent. Long use in a tradition shows that people valued it, but it is not proof that it works or that it is safe.
The most important safety point is simple. Heart symptoms need a doctor, not a tea.
No one has shown how flor de manita acts in the human body.
Most of what is known comes from the lab. In test-tube and animal studies, flower extracts relaxed the smooth muscle of the gut. Some animal work also found a drop in bowel contractions and in the fluid lost during diarrhoea.
Researchers think the flavonoids and tannins in the flower drive these effects. Tannins are astringent, which means they tighten tissue. That may explain the old use for loose stools, but it has not been tested properly in people.
A few animal studies report mild calming effects and small changes in blood pressure. Whether a cup of the tea does any of this in a person is unknown.
The traditional heart use seems to come from the shape of the flower. A hand-shaped bloom was read as a sign for the heart. That is folklore, not a measured effect on heart rhythm.
Flor de manita is sold in a few simple forms.
- Whole dried flowers, loose by weight, in Mexican and Latin American markets. - Pre-packed tea bags, alone or blended. - Liquid tinctures and, less often, capsules.
It also turns up in mixed teas. One is "té de tres flores", often blended with linden (tila) and zapote blanco.
Mixed teas are the main problem for a buyer. A heart or nerve blend may hold plants with real drug effects, such as zapote blanco. You may not know what you are drinking.
Read the full plant list before you buy. If the label only says "herbal blend", treat that as a reason to skip it.
Flor de manita has a long and well recorded place in Mexican tradition. The Nahuatl name macpalxóchitl means "hand flower". Aztec gardens held the tree, and Spanish chroniclers of the 16th century described it.
Healers linked the hand shape to the heart. The flower was brewed for a pounding or skipping heartbeat, for grief and for restless sleep. It also appeared in remedies for dysentery and belly cramps.
The tree itself became famous. Single specimens were treated as sacred and were guarded for centuries.
This history explains why the flower is trusted in many households. It does not tell you what the tea does inside a body. It is not a reason to treat a heart problem at home.
Stop and get urgent help if you have chest pain, fainting, a heartbeat that will not settle, or trouble breathing. Swelling of the lips, tongue or throat is an emergency.
See a doctor soon if your heartbeat feels odd for more than a day or two. The same goes for diarrhoea lasting over 48 hours, or any blood in your stool.
See a doctor before starting it if you take heart, blood pressure or blood-thinning medicine. Tell them you are considering it.
In Mexico it is sold freely as a traditional herbal remedy and market herb. In the United States it is a dietary supplement, not approved by the FDA to treat any disease. The UK and EU have no authorised herbal medicine made from it.
