Osteoarthritis ✪✪✪✪✪
Rosehip appears to have beneficial effects for treating osteoarthritis, particularly knee osteoarthritis. Most clinical research shows that taking the equivalent of 2 g of rosehip powder twice daily for 3-4 months reduces pain and stiffness, and improves function and mobility in patients with osteoarthritis compared with placebo. A meta-analysis of three randomized controlled trials involving 287 patients with osteoarthritis reported that a 3-month treatment with rosehip powder consistently reduced pain scores compared with placebo. Some studies and a meta-analysis have found that rosehip powder is more effective than glucosamine hydrochloride for reducing osteoarthritis pain. This analysis combined data from three glucosamine studies involving 933 patients and three rosehip studies with 287 patients. ESCOP states that rosehip with achenes included is used as an adjunct for the relief of pain and joint stiffness associated with osteoarthritis.

Rheumatoid arthritis ✪✪✪✪✪
In a 6-month trial of 89 patients with rheumatoid arthritis, daily intake of 5 g of rose hip powder showed a significant improvement in disability scores as well as a reduction in erythrocyte sedimentation rate (a non-specific marker of inflammation), compared with placebo. However, these results, although promising, are modest and require further studies to be confirmed. Moreover, a smaller open study of 20 women with rheumatoid arthritis and 10 controls did not show a significant effect on clinical symptoms or biological markers of inflammation after 4 weeks of treatment with 10.5 g/day of rose hip powder.

Urinary tract infections ✪✪✪✪✪
Preliminary clinical research shows that taking 500 mg of rose hip powder twice daily, starting 2 days postpartum and continued for 20 days, reduces the odds of developing a culture-positive asymptomatic urinary tract infection by 68% compared with placebo in women who have undergone cesarean section. However, rose hip does not appear to reduce the incidence of symptomatic cystitis in these patients.

ENT infections ✪✪✪✪✪
The buds are used for recurrent mucous membrane inflammations, especially in children: sore throats, tonsillitis, ear infections, bronchitis, sinusitis, tracheobronchitis… The ESCOP states that the rosehip is used as an adjunct in the treatment of colds and chill-related conditions. Efficacy for this indication is plausible based on long-standing use. Gemmotherapy concentrated (tincture): - in adults: 5 to 10 drops in the morning. - in children: 1 drop per 10 kg of body weight

Properties
Antioxidant
The antioxidant activity of rose hip is attributed to its high content of phenolic compounds, flavonoids, and vitamin C. Even when vitamin C is removed in some experiments, it still exhibits significant antioxidant activity. Various in vitro and clinical studies suggest that rose hip has protective effects against oxidative stress, increases the activity of antioxidant enzymes such as superoxide dismutase and catalase, and inhibits lipid peroxidation.
Usages associés
Anti-inflammatory
Studies indicate that rose hip powder may have anti-inflammatory properties. In laboratory settings, it appears to reduce the activity of certain white blood cells (polymorphonuclear leukocytes) and decrease levels of certain inflammatory proteins (C-reactive protein). Interestingly, these effects do not appear to be related to the vitamin C present in rose hip. A specific galactolipid found in rose hip, called GOPO, may play a key role in these anti-inflammatory properties. It may help reduce inflammation, as well as levels of C-reactive protein and creatinine. In people suffering from osteoarthritis, this could translate into reduced pain and improved joint mobility. A major advantage of rose hip compared with conventional nonsteroidal anti-inflammatory drugs (NSAIDs) is that it does not cause gastric ulcers, nor does it affect blood clotting or clot formation, making it a safer option for people who might be at risk of gastrointestinal or cardiovascular problems related to NSAID use.

Gastroprotective
A decoction of fresh fruits, prepared and then tested in vivo in a rat model of ulcerogenesis, showed a gastroprotective effect against lesions induced by ethanol. The observed effects are even superior to those of misoprostol (0.4 mg/kg), an anti-ulcer drug used as a reference, particularly regarding epithelial lesions of the stomach.
Hypoglycemic
The dog rose, traditionally used in the treatment of diabetes, has shown beneficial effects in animal studies. In diabetic rats, it helped lower blood glucose levels. Similarly, in mice given a dose of glucose, the dog rose helped reduce their blood glucose without affecting their appetite, weight gain, or fat accumulation.
Diuretic
Rose hips contain pectin, citric acid, and malic acid, which may have diuretic activity.

Safe dosage
Adults aged 18 and over: 5 g (powder)
A starting dose of about 5 g/day (achenes included) for 3-4 weeks, followed by a maintenance dose of 2.5 g/day, is recommended to treat osteoarthritis or chronic inflammation with the standardized extract. Rosehip should be taken with meals to improve the absorption of its lipid components. Gemmotherapy: 5 drops twice a day in a glass of water. Dilution 1 DH: 50 drops twice a day in a glass of water. A 3-week course to be repeated.
Child aged 5 and over: 1 drop/10 kg (gemmotherapy)
Gemmotherapy: 1 drop per 10 kg in a glass of warm water, only once a day. In Dilution 1 DH: 20 drops in the morning, in a glass of warm water, or 1 drop per kilogram of body weight per day.
Interactions
Médicaments
Antiplatelet agents/Anticoagulants: moderate interaction
Evidence from in vitro and animal research suggests that a component of rosehip, rugosine E, may induce platelet aggregation. Theoretically, concomitant use of rosehip could reduce the effectiveness of antiplatelet or anticoagulant medications. Some anticoagulant or antiplatelet drugs include aspirin, clopidogrel (Plavix), dalteparin (Fragmin), enoxaparin (Lovenox), heparin, ticlopidine (Ticlid), warfarin (Coumadin), and others.
Estrogens: moderate interaction
Theoretically, large amounts of vitamin C, present in rosehip, could increase the absorption and effects of estrogens.
Lithium: moderate interaction
Rosehip may have diuretic properties. Theoretically, because of these potential diuretic effects, rosehip could reduce excretion and increase lithium levels. It may be necessary to decrease the lithium dose.
Plantes ou autres actifs
Rosehip: moderate interaction
Concurrent use of iron and rosehip interacts with vitamin C; 200 mg of vitamin C per 30 mg of elemental iron increases oral iron absorption, particularly ferric iron.
Rosehip: moderate interaction
Because of the vitamin C content of rosehip, concurrent use of rosehip with vitamin C supplements could increase the risk of adverse effects associated with vitamin C.
Precautions
Kidney stones: use with caution
Large amounts of vitamin C in rosehip may increase the risk of oxalate stone formation.
Hemochromatosis: use with caution
Use rosehip with caution, because its vitamin C content can increase iron absorption, which could worsen hemochromatosis.
Myocardial infarction: use with caution
A component of rosehip, rugosine E, may induce platelet aggregation. Theoretically, taking rosehip could increase the risk of thrombosis in people with a history of myocardial infarction.
Pregnancy: use with caution
There are few publications on the use of rosehip during pregnancy. Rosehip tea is traditionally recommended during pregnancy and there are no reports of adverse effects.
Breastfeeding: use with caution
There is not enough reliable information available on the safety of rosehip.
