Coat buttons is a low, sprawling weed with small daisy-like flowers. Its botanical name is Tridax procumbens. In Yoruba it is known as Muwagun.
It grows almost everywhere in West Africa, on roadsides, farm edges and waste ground. Healers crush the fresh leaf onto cuts, grazes and boils. Leaf teas are also drunk at home for fever, stomach upset and "liver" trouble.
The honest verdict: nearly all the research is in test tubes and rodents. Proper human trials are missing. Long traditional use is not proof that a remedy works, and it is not proof that it is safe.
This page covers what tradition claimed, what the science actually shows, and who should steer clear.
No one has shown how coat buttons works in people. What exists is laboratory and animal work, and that is a much weaker base.
In test tubes, leaf extracts slow the growth of some bacteria and fungi. Whether that happens on a real wound, at real strengths, is not established.
In rats, leaf extracts have closed wounds faster and raised collagen, the protein that knits skin together. Rodent work also reports lower blood sugar, lower blood pressure and some liver protection. These are animal findings, not results measured in humans.
In cell studies the flavonoids mop up free radicals, which are unstable molecules that damage tissue. Lab tests also suggest the extract damps some inflammation signals. Again, this is bench work, not a proven effect in your body.
So the mechanism story is a set of plausible leads. None of it tells you what a cup of leaf tea will do.
Coat buttons is mainly a home remedy, not a shop product. Fresh leaf is the usual form across West Africa.
Forms you may meet: - Fresh leaves crushed into a pulp for skin - Juice squeezed from fresh leaf - Infusion or boiled decoction of leaf or whole plant - Dried powdered leaf, sometimes in capsules - Alcohol tinctures and extracts sold online - Herbal soaps, creams and hair washes
Products sold online are rarely tested. Strength, purity and even the plant identity can be wrong.
Plants picked from roadsides carry their own problem. They can hold road dust, soil bacteria, farm spray or heavy metals.
Coat buttons has a long record in West African home healing. Yoruba speakers call it Muwagun.
Healers crushed the fresh leaf and pressed it onto cuts and scrapes. The aim was to slow light bleeding and keep the sore clean. Pulped leaf was also laid on boils and skin eruptions.
Leaf teas were drunk for fever, loose stools and complaints blamed on the liver. Some households used a leaf wash on the hair and scalp.
The plant spread widely as a weed and picked up uses elsewhere. It appears in Indian folk practice for wounds and liver trouble, and in parts of Latin America. In several regions it also serves as animal fodder.
None of this history was tested the way a medicine is tested.
Stop and get medical help the same day if a wound gets hotter, more red, more painful, or starts leaking pus. Red streaks spreading from the sore, a fever or shivering mean infection is spreading.
Go to an emergency department now for swelling of the lips, tongue or throat, a widespread rash, wheezing or trouble breathing. That can be a severe allergic reaction.
See a doctor promptly for yellow eyes or skin, dark urine, or pain under the right ribs. Also seek care for bleeding that will not stop after ten minutes of firm pressure.
If you have diabetes, treat shakiness, sweating or confusion as low blood sugar and act on it at once.
Fever with chills in a malaria area needs a test and proper treatment, not a leaf tea.
Coat buttons is not an approved medicine in the UK, the EU, the US or Canada. Where it is sold, it is a herbal supplement, and supplements are not checked for strength or purity the way drugs are.
In Nigeria and Ghana it is mainly a home remedy, while packaged herbal products need registration with the national food and drug agency.
