What is Rose hip (cinnamon rose)?

Rose hip is the red fruit left behind after a rose flower drops its petals. Cinnamon rose (Rosa majalis) is a wild rose of Norway, Sweden, Finland and northern Russia. Its hips are called nyper in Norwegian, and the bush itself is kanelrose.

The hips are picked in late summer and autumn, often after the first frost. People dry them, then make soup, tea, syrup or jam. Dried hips are also milled into a powder and sold in tubs or capsules for sore joints.

Here is the short verdict. Rose hips are a real food source of vitamin C, and vitamin C prevents and treats scurvy. For joint pain the human evidence is modest, mixed and mostly based on a close relative, Rosa canina.

Long use in Scandinavia is not proof that rose hip works, and it is not proof that it is safe. Both have to be judged on their own. For most healthy adults, food amounts are treated as low risk.

How does Rose hip (cinnamon rose) work?

Only one part of the story is settled. Rose hips hold vitamin C, and vitamin C prevents and treats scurvy. That is a proven effect in people, not a theory.

The joint-pain claim rests on softer ground. Rose hip powder holds a fat-like compound called GOPO, plus plant pigments and polyphenols (plant chemicals found in fruit and tea).

In cell studies, GOPO appears to slow the movement of white blood cells toward inflamed tissue. In test tubes, rose hip extracts seem to damp some of the signals that drive swelling. Whether this happens in a human joint after you eat the powder is not established.

Animal work points the same way, with less swelling in treated animals. Animal results often fail to repeat in people, so treat them as a lead, not an answer.

The vitamin C in rose hip also helps your gut take up iron from plant foods. That is a known effect of vitamin C from any source.

What forms does Rose hip (cinnamon rose) come in?

Rose hip turns up in both food and supplement form:

Dried whole or halved hips, for tea and for the classic nypesuppe (rose hip soup).

Fine milled hip powder, sold loose in tubs. This is the form used in most joint-pain trials.

Capsules and tablets of the same powder or of a concentrated extract.

Syrup and cordial, often sweetened. Sugar content can be high.

Jam, jelly and soup mixes, treated as ordinary food.

Rose hip seed oil, a cosmetic oil for the face and scars. It is for skin only.

Products differ widely in what they contain. Many are made from Rosa canina rather than Rosa majalis, and labels do not always name the species. Vitamin C levels also swing with drying and age, so two tubs are rarely the same.

Where it comes from:

Rose hips have a long, well-recorded place in Nordic kitchens and folk practice. Households gathered nyper in autumn and dried them over the stove for winter.

Sweetened rose hip soup and tea were everyday food in Sweden, Norway and Denmark. Folk use also covered colds, tiredness, loose joints and "flushing" the urinary tract. None of those older uses were tested at the time.

During the Second World War, Nordic and British authorities organised hip picking when citrus fruit could not be shipped. The goal was vitamin C, and that part of the history holds up well. Rose hip syrup was handed out to children in several countries.

The joint-pain use is much newer. Danish rose hip powder products were studied from the late 1990s onward, which is where most of the modern research comes from.

What does Rose hip (cinnamon rose) help with?

• Osteoarthritis pain in the hip and knee: This is the best-studied modern use, and the result is modest. Several small trials of rose hip powder report a small fall in pain scores against placebo over about three months. A pooled analysis of three of those trials found the effect real but small (PMID 18407528). Many people in the trials felt no change at all. The trials used Rosa canina powder, not Rosa majalis. Some had industry funding. Nothing shows that rose hip slows or repairs joint damage.
• Keeping up vitamin C intake, and preventing scurvy: This one is solid, but it is about vitamin C rather than about rose hip magic. Vitamin C prevents and treats scurvy, and rose hips are a rich food source. This is why Nordic households and wartime schemes pushed rose hip syrup. Drying and heat cut the vitamin C sharply, so the amount in a given product is hard to predict. Scurvy is rare today. If you eat fruit and vegetables most days, you are very unlikely to need rose hip for this.
• Rheumatoid arthritis symptoms: The evidence here is thin and should not be leaned on. One small trial of rose hip powder in rheumatoid arthritis reported better patient-rated function, with no clear change in blood markers of inflammation. Rheumatoid arthritis is an autoimmune disease that damages joints over time. It needs prescribed treatment. Rose hip has not been shown to replace any part of that care. Treat it only as a possible extra to discuss with your rheumatologist.
• Colds and winter tiredness: Tradition claimed a lot here, and the evidence does not back it. Rose hip tea and syrup were common Nordic winter comforts. Vitamin C supplements do not stop healthy adults catching colds, and at best shorten them slightly. No good trial shows rose hip itself cuts cold illness. A warm drink can still be soothing. Just do not expect it to change how long you are ill.
• Mild constipation: Any effect here is likely down to fibre and fluid, not the plant. Rose hips hold pectin, a soluble fibre, and the whole fruit adds bulk. There are no good human trials of rose hip for constipation. Large amounts of the powder can loosen stools, which some people treat as the point. Persistent constipation needs a cause found, not a home remedy.

Which foods are rich in Rose hip (cinnamon rose)?

Rose hip is itself a food. In the Nordic countries it shows up as nypesuppe (rose hip soup), tea, syrup, jam and jelly.

Fresh hips lose vitamin C fast once dried, heated or stored. Other everyday foods carry vitamin C more reliably, such as blackcurrants, peppers, broccoli, citrus fruit and potatoes.

Never eat raw hips whole without removing the seeds and the hairs around them.

What are the side effects of Rose hip (cinnamon rose)?

• Stomach cramps or heartburn
• Loose stools or diarrhoea, mostly with larger amounts
• Nausea
• Wind and bloating
• Headache or trouble sleeping, reported in some trials
• Itching and skin irritation from the fine hairs inside raw hips
• Allergic reaction, including rash, wheeze or swelling (rare)
• Breathing irritation from inhaling the powder dust (rare)

Good to know:

Most side effects are mild and settle when you stop. Gut upset is the common one, and it is more likely with the powder than with tea or soup.

Serious reactions are rare. Allergy to rose hip exists but is uncommon, and tends to show as rash, itching or wheeze.

The hairs inside raw hips are a real nuisance. They were once used as itching powder, so hips must be cleaned and sieved before eating.

How much Rose hip (cinnamon rose) should you take?

• Recommended daily: This is what labels carry, not advice for you. Tubs of rose hip powder commonly state 5 grams a day, often split into two servings. Capsule products often hold 500 mg each, with labels suggesting several per day. Food uses have no set amount. Soup, jam and tea are eaten as food. Strength varies a lot between brands, so one tub is not equal to another. Check with a pharmacist or doctor before using supplement doses, especially if you take any regular medicine.
• Best time of day: Timing does not appear to matter. Nothing in the research points to morning or evening being better. People who split the powder into two servings often take one with breakfast and one with the evening meal. That is a habit, not a rule.
• With or without food: Food is the easier choice for most people. Rose hip powder is tart and acidic, and can bother an empty stomach. Taking it with a meal may cut heartburn and loose stools. Mixing the powder into yoghurt, porridge or juice is common.
• Time to effect: Be patient, and be ready for nothing. In the joint-pain trials, any change in pain took about three weeks to show, and grew a little by three months. Many people in those trials felt no benefit at all. Rose hip may do nothing for you. For vitamin C intake, the effect on blood levels starts within days of regular use.
• How long to take it: Joint-pain trials mostly ran for three to four months. That is the longest span with any human data behind it. Longer daily use has not been well studied in trials. If pain is not better after about three months, there is little reason to keep paying for it. Food amounts in soup or jam are eaten year-round in the Nordic countries without known harm.
