What is yanrin?
Yanrin is a leafy green eaten across West Africa. Its plant name is Launaea taraxacifolia. The leaves are bitter and taste a little like dandelion.
It is both a food and a folk remedy. Cooks boil the leaves into stews and soups. Healers have given leaf water for stomach, sugar and liver complaints.
Do not mix it up with the other "wild lettuce", Lactuca virosa. That is a different plant with a milky sap, sold as a sleep aid. The two share a common name and nothing else.
The verdict is simple. As a vegetable, yanrin is an ordinary food. As a medicine, human evidence is close to none.
Long use in tradition is not proof that it works. It is also not proof that it is safe. That caution applies to every claim on this page.
How might yanrin work?
Almost all of the research is lab dish and animal work. Very little has been tested in people.
In test tubes, yanrin extracts soak up free radicals. This is linked to the flavonoids and phenols in the leaf. Whether that does anything in your body is unknown.
In rats, leaf extracts have lowered blood sugar and blood fats in some studies. The doses used were often large. The same effect has not been shown in humans.
In animals, some extracts calmed gut spasm and reduced stomach damage. These are early findings. Treat them as leads, not as results.
The plainest thing it does is feed you. The leaves supply fibre, minerals and vitamin A building blocks. That part needs no hedging.
How is it sold and used?
Fresh leaves are the main form. In Nigeria they are cooked as efo yanrin, a stewed green dish.
Other forms you may meet:
Young raw leaves in salad, often dressed with oil and pepper.
Dried leaf, crumbled into soups and sauces.
Dried leaf powder, sold loose or in sachets.
A water infusion, or a drink made from boiled leaves.
Capsules and liquid extracts, mostly sold online.
Labelling is often loose. Many products sold as "wild lettuce" are Lactuca virosa, not yanrin.
Check the botanical name before you buy. If the label does not say Launaea taraxacifolia, you cannot be sure what is inside.
What did tradition claim?
Yanrin has a long record as a food plant in West Africa. Yoruba, Igbo and Ghanaian cooks have used the leaves for generations.
Healers gave leaf water for stomach upset, poor appetite and liver complaints. It was also used for sugar problems and as a general tonic. Some communities applied crushed leaves to wounds.
The plant grows wild on farm edges and roadsides. People gathered it freely, so it became a cheap green in lean seasons.
These accounts come from surveys of plant use, not from trials. They record custom. They do not test whether it helped.
Stop and get medical help straight away if you get a spreading rash, swollen lips or face, or trouble breathing.
See a doctor soon if you notice shaking, sweating or confusion that may mean low blood sugar.
Also see a doctor if you get lasting stomach pain, vomiting, dark urine, or yellow eyes or skin.
Any symptom you were hoping yanrin would fix, such as thirst, weight loss or ongoing tiredness, needs proper assessment instead.
In Nigeria, Ghana and Benin, yanrin is an everyday vegetable sold in markets. In the UK, EU and US it is treated as a food or food supplement, not a licensed medicine. No health claim for it has been approved by a regulator.
