Matico is the leaf of Piper aduncum, a shrubby tree in the pepper family. It grows across tropical Latin America. Folk healers used the dried leaf as a wound wash and as a stomach tea.
The plant has spread far beyond its home range. It is now a common weedy tree in parts of Asia and the Pacific. The leaf has a spicy, peppery smell when crushed.
One name covers two plants, so read labels with care. In Chile, matico usually means Buddleja globosa, a different and unrelated plant. Check for the Latin name Piper aduncum on any product.
Here is the honest verdict on the evidence. Almost all the research is in test tubes and animals, not in people. Long use in tradition is not proof that matico works, and it is not proof that it is safe.
No one has shown how matico acts in the human body, because the human studies have not been done.
In test tubes, leaf extracts slow the growth of some bacteria and fungi. Lab work also shows activity against Leishmania parasites and against insects and snails. Whether any of that happens inside a person is unknown.
The leaf oil is often rich in dillapiole. In cell and animal studies, dillapiole blocks some liver enzymes that break down drugs. That finding is one reason the concentrated oil is treated with care.
Tradition held that the leaf stops bleeding and tightens raw tissue. The leaf does contain tannins, which bind protein in a test tube. No reliable human trial shows that matico speeds wound healing.
Some lab studies report that leaf extracts calm markers of inflammation in cells. That is an early signal, not a proven effect in people.
Matico is sold mainly as a dried leaf for tea.
- Loose dried leaf and tea bags, steeped in hot water. - Tinctures, which are alcohol extracts in dropper bottles. - Powdered leaf in capsules.
- Essential oil, steam distilled from the leaf. This is a strong concentrate, not a drink. - Soaps, washes, ointments and creams sold for skin use.
Quality is uneven across the market. Few makers test the oil content. Some products sold as matico contain Buddleja globosa instead.
Matico has a long record in Latin American folk medicine.
Healers in Peru, Ecuador, Bolivia, Colombia and Brazil used it widely. They pressed crushed or boiled leaf onto cuts, sores and insect bites. Leaf tea was taken for upset stomach, loose bowels and urinary complaints.
Spanish colonial accounts carried the plant's name to Europe. In the 1800s matico appeared in British and American pharmacy books. It was listed there as a wound herb and a remedy for bleeding.
It faded from mainstream pharmacy as modern drugs arrived. Local use in Latin America carried on.
The tree also had jobs outside medicine. It was used as a fish poison, an insect repellent and a cover crop on rested farm plots.
Stop matico and get medical help the same day if you notice any of these:
- yellow skin or eyes, dark urine, pale stools, or pain under the right ribs - a rash with swelling of the lips, face or tongue, or trouble breathing - a wound that turns red, hot, swollen or oozing, or red streaks spreading from it - fever with a sore throat, a wound, or back pain - blood in your urine, stool or vomit - diarrhoea lasting more than two days, or any diarrhoea in a young child or older adult
See a doctor sooner rather than later if a complaint does not improve within a few days. Tell any clinician treating you that you have been using matico.
In the United States matico is sold as a dietary supplement, and the FDA has not approved it as a medicine. In the UK and EU it is not an approved herbal medicine, while in several Latin American countries it is sold freely as a folk remedy.
