Wild raspberry is a thorny shrub of Nordic forests, clearings and old burn sites. People use two parts of it. The red berry is eaten as food, and the dried leaf is brewed as a tea.
The plant is known as bringebær in Norway, hallon in Sweden, vadelma in Finland and hindber in Iceland. Garden raspberries are the same species, Rubus idaeus. Wild fruit is usually smaller and sharper in taste.
Here is the honest summary. The berry is a good everyday food, high in vitamin C and fibre. The leaf tea, best known for use in late pregnancy, has only thin and mixed human evidence behind it.
Long use in Nordic homes is not proof that the leaf works, and it is not proof that it is safe. That point applies to every claim on this page.
No one has shown clearly how raspberry leaf acts in the body.
The leaf is rich in tannins. In test tubes, tannins bind proteins and tighten tissue. That is why the tea tastes dry, and why it was used as a gargle.
Older animal and isolated-tissue studies looked at fragarine, a compound from the leaf. The results were mixed. Womb muscle sometimes relaxed and sometimes tightened.
Those tests were not done in pregnant women. They tell you nothing certain about labour.
The berry works as plain food. It supplies vitamin C, fibre and water. Vitamin C is needed for healthy skin, blood vessels and wound healing.
That last point is well established in people. The claims about the leaf are not.
Berries also hold anthocyanins, the red plant pigments. In lab tests these act as antioxidants, which means they slow damage from unstable molecules. Whether eating them changes your health in a measurable way is still unclear.
Fresh and frozen berries are the most common form in the Nordic countries.
You will also meet jam, juice, syrup, dried berries and berry powder.
The leaf is sold dried, as loose tea or tea bags. Tablets and capsules of leaf powder are also sold, often aimed at the last weeks of pregnancy.
Tinctures, which are alcohol extracts of the leaf, exist but are less common.
Raspberry seed oil is sold for skin care. Raspberry flavour in sweets and drinks is usually artificial and holds no plant material.
Raspberries grew wild across Norway, Sweden, Finland and Iceland, and country people picked them every summer.
Berries were eaten fresh, dried, or cooked into jam, juice and soup for the winter months.
Home healers brewed the dried leaf as a tea. It was given for loose stools, sore throats and painful periods.
Midwives in the Nordic countries, and across much of Europe, gave leaf tea in the last weeks of pregnancy. They believed it made labour easier.
The leaf was also used as a mouth rinse and as a wash for small wounds.
Most of this was passed on by word of mouth. Written records are patchy and rarely say how much was used.
Stop raspberry leaf and call your midwife or maternity unit if you get contractions, bleeding or fluid loss before your due date.
Get urgent help if your baby moves less than usual.
Stop and seek care for signs of allergy: swelling of the lips or tongue, a spreading rash, or trouble breathing. Call emergency services if breathing is hard.
See a doctor if diarrhoea lasts more than two days. Go sooner for a baby, a small child or an older adult.
Tell your doctor if you take diabetes medicine and your blood sugar readings start to drop.
In the Nordic countries, the wider EU, the UK and the US, raspberry is an ordinary food. Dried leaf is sold as a herbal tea or a food supplement. It is not licensed as a medicine, so sellers may not claim it treats any disease.
