A rose hip is the red fruit left on the dog rose bush after the flower drops. The plant is Rosa canina, a wild rose of hedges, dunes and roadsides. In the Nordic countries the fruit is called nype, nypon or ruusunmarja.
The fruit is eaten as soup, jam, syrup and tea. It is also dried and milled into a powder of shells and seeds, sold in tubs and capsules. Most supplement buyers are looking for help with stiff, sore joints.
Here is the honest verdict. Rose hip powder has been tested in people with osteoarthritis (worn, painful joints), and the average benefit was small. Most other claims rest on long tradition and lab work, and tradition is not proof that something works or that it is safe.
Rose hip is a food first. Eating it in normal kitchen amounts is a different matter from taking concentrated daily capsules.
Part of the story is settled, and part is not. Rose hips are rich in vitamin C, and vitamin C prevents and treats scurvy. That much is proven in people and should not be hedged.
The joint claims are shakier. Rose hip shells and seeds contain a fat-like compound known as GOPO. In laboratory tests, GOPO appears to slow white blood cells that drive swelling.
Rose hip extracts also lower markers of swelling in cell and animal studies. Whether the same thing happens inside a human knee is not established. Human trials exist, but results differ and the average effect is modest.
The fruit also holds polyphenols and carotenoids, which act as antioxidants in test tubes. Antioxidant activity in a dish does not predict how you will feel. That link has not been shown in people.
One practical point matters more than the theory. Heat and drying destroy much of the vitamin C in rose hips. So a cup of long-boiled soup is not the vitamin source a fresh hip is, and the content of any product can vary a lot by batch.
Common forms include:
- Dried whole or cut hips for tea and infusions.
- Rose hip powder made from dried shells and seeds, sold loose or in capsules. This is the form used in most joint trials.
- Tablets and capsules, often standardised to a stated GOPO level.
- Syrup, long given to children in Britain and the Nordic countries.
- Nyponsoppa, the Swedish rose hip soup, sold as an instant powder in most Nordic shops.
- Jam, jelly and fruit teas blended with hibiscus.
- Rose hip seed oil, which is pressed from the seeds and used on the skin, not swallowed.
Labels vary a great deal. Check whether a product is a food, a vitamin C supplement or a standardised joint powder, because they are not the same thing.
Rose hips have been gathered across Scandinavia for centuries. Pickers waited until after the first frost, when the fruit softens and sweetens. The hips were dried for winter or cooked into soup and jam.
Folk use went beyond food. The fruit was given for colds and coughs, as a warming winter drink, and as a mild laxative. Tea from the hips was also used as a "blood cleanser" and to increase urine, both vague ideas by modern standards.
The most documented chapter is wartime. During and after the Second World War, Nordic and British authorities organised children and volunteers to pick wild hips. The fruit was turned into syrup to supply vitamin C when citrus could not be imported.
The joint use is newer. Danish work from the 1990s onward turned rose hip seed and shell powder into a commercial supplement for arthritis, which is where most modern research comes from.
Stop and get emergency help if you have swelling of the lips, face, tongue or throat, a spreading rash, or trouble breathing. These are signs of a severe allergic reaction.
See a doctor soon if you have severe pain in your side or back, or blood in your urine. These can be signs of a kidney stone.
See a doctor if you take a blood thinner and notice unusual bruising, nosebleeds or bleeding gums.
Book a normal appointment if your joint pain is getting worse, a joint becomes hot or swollen, or you have a fever. Also see a doctor if stomach upset or diarrhoea lasts more than a few days after stopping.
In the EU, UK, Norway and the United States, rose hip is an ordinary food. It is also sold as a food supplement.
It is not a licensed medicine for arthritis in these places. Supplement makers may not legally claim it treats a disease.
