Canchalagua is a bitter herbal tea made from a small weedy plant of the daisy family. Its botanical name is Schkuhria pinnata. In Peru, Bolivia and northern Argentina, the dried flowering tops are brewed and drunk as a folk remedy.
The name causes real confusion. In Chile and parts of Mexico, "canchalagua" can mean a quite different plant, such as a Centaurium species. Always check the Latin name on a label before you buy.
Folk users take it for fever, skin rashes, stomach and liver complaints, and "blood cleansing". The honest verdict: human evidence is very thin, and no use is proven. Long traditional standing is not proof that it works, and it is not proof that it is safe.
Almost everything known about how this plant acts comes from test tubes and animals, not people.
In laboratory dishes, extracts of Schkuhria pinnata slow the growth of the parasite that causes malaria. Extracts have also slowed some bacteria and fungi in culture. Whether any of this happens in a person drinking tea is not established.
In animal studies, extracts have reduced swelling and some markers of inflammation. A few animal reports also suggest lower blood sugar. These are early signals, not proof of a treatment effect.
The plant is bitter. Bitter teas can trigger saliva and stomach juices, which may explain the old use as a digestive tonic. That idea fits tradition, but it has not been tested for this plant.
You will most often meet it as loose dried herb, sold by weight in Andean markets.
Other forms include:
- Tea bags of the cut, dried plant - Alcohol tinctures (liquid extracts) - Capsules of dried powder - Cooled tea used as a skin or hair wash - Mixed "blood cleanser" blends with other herbs
Blends are the hardest to judge. They may hold herbs with their own risks, and the label may not list amounts. Products rarely state the Latin name, so you cannot always tell which plant you have.
Canchalagua has a long place in Andean home medicine. Herb sellers in Peru and Bolivia have offered it for generations.
Healers used it as a bitter tonic for fever, liver trouble and sluggish digestion. It was also brewed as a wash for itchy skin, boils and sores. In folk terms it was called a "blood purifier", an old idea with no modern meaning.
The plant later spread as a weed to Africa and parts of Asia. In some African regions, people adopted it for fever and malaria. These records describe what people did, and nothing more.
Stop and get emergency help for hives, swelling of the lips, tongue or face, or trouble breathing.
See a doctor the same day if you have a high fever, shaking chills, or fever after travel to a malaria area. Do not wait on herbal tea.
Also book a doctor if you get yellow skin or eyes, dark urine, belly pain, a spreading rash, or signs of low blood sugar such as sweating and confusion. Stop the herb first.
In the United States it may be sold as a dietary supplement. It is not approved by the FDA to treat any illness.
In the UK and EU there is no licensed herbal medicine made from it; it is sold as a herbal tea. In Peru and Bolivia it is an ordinary market herb.
