Ramsons, also called wild garlic, is a leafy spring plant in the onion family. It grows in damp woods across Norway, Sweden, Finland and much of Europe. The broad green leaves smell strongly of garlic when you crush them.
In the Nordic countries it is known as ramsløk, ramslök and karhunlaukka. People eat the leaves raw or cooked. It is also sold dried, in capsules and as a tincture.
One warning comes before anything else. Deadly plants grow in the same woods and look like ramsons before it flowers. People have died after picking the wrong leaves.
As a food, ramsons is an ordinary green vegetable. As a remedy, the human evidence is thin and weak. Long use in Scandinavian kitchens and folk medicine is not proof that it works, and it is not proof that it is safe.
The short answer: most of the proposed action comes from lab work, not from people.
The intact leaf holds a compound called alliin. Crushing or chewing sets off an enzyme that turns alliin into allicin. Allicin gives the plant its smell and bite.
In test tubes, allicin and related sulphur compounds slow many bacteria and fungi. Whether that happens in the body after a meal is not established.
In cell and animal studies, extracts appear to relax blood vessels. They also appear to block ACE, an enzyme that pushes blood pressure up. Animal work suggests small falls in blood fats.
Test tube work suggests the sulphur compounds make platelets less sticky. Platelets are the blood cells that help clots form. This is the basis of the bleeding warning, though much of that research used common garlic, not ramsons.
Fresh leaf, picked in spring, is the main form in Scandinavia.
- Fresh leaves. Eaten raw in salad, blended into pesto, or stirred into soup and butter.
- Flower buds and flowers. Usually pickled, or scattered over food.
- Bulbs. Small and edible, but digging them kills the plant and is banned in some places.
- Dried leaf and leaf powder. Milder in taste, used in herb salt or as a tea.
- Capsules and tablets of dried leaf.
- Fresh plant tinctures and pressed juice.
- Frozen leaf, oils and salt blends, sold to stretch the short season.
The season is short, roughly April to May in the Nordic region. Leaves turn tough and bitter once the plant flowers. Products made from old or dried leaf taste and smell much weaker.
Ramsons has been gathered in northern Europe since prehistoric times. Leaf traces have turned up at Stone Age sites in Denmark.
Nordic country people treated it as a spring food after months of stored and salted fare. Old folk texts called it a blood cleanser and a spring tonic.
Herbals also recorded it for stomach trouble, worms, coughs and chest complaints. Crushed leaves were laid on wounds and boils.
The names carry the same story. Ramslök and ramsløk are the old leek names. The Finnish karhunlaukka means bear's leek, and the Latin ursinum also means bear.
Get emergency help at once if you think you ate the wrong plant. Bring a sample or a photo of what you picked.
Warning signs after a foraged meal include vomiting, a burning mouth, a slow or uneven heartbeat, or heavy diarrhoea some hours later. Symptoms from autumn crocus can start late and still be serious.
Call emergency services for swelling of the lips, tongue or throat, or any trouble breathing. That is a severe allergic reaction.
See your doctor if you bruise easily, bleed longer than usual, or pass black stools while taking supplements. Also check in if a rash or stomach pain does not settle after you stop.
In Norway, Sweden, Finland and the wider EU, ramsons is an ordinary food. Dried leaf, capsules and tinctures are sold as food supplements, not as medicines.
Picking rules differ by country. The Norwegian and Swedish right of access allows picking herbs on uncultivated land. Some countries, parks and nature reserves protect the plant or ban digging up bulbs.
