What is it?
Fresh rose hip contains vitamin C, so some people take it as a source of vitamin C. However, much of the vitamin C in rose hip is destroyed during drying and processing. Rose hip is used for osteoarthritis and pain after surgery. It is also used for many other conditions, but there is no good scientific evidence to support these other uses.
In foods and in manufacturing, rose hip is used for tea, jam, soup, and as a natural source of vitamin C.
How effective is it?
Natural Medicines Comprehensive Database rates effectiveness based on scientific evidence according to the following scale: Effective, Likely Effective, Possibly Effective, Possibly Ineffective, Likely Ineffective, Ineffective, and Insufficient Evidence to Rate.
The effectiveness ratings for ROSE HIP are as follows:
Possibly effective for...
- Osteoarthritis. Most research shows that taking rose hip by mouth can reduce pain and stiffness and improve function in people with osteoarthritis.
- Pain after surgery. Some research shows that taking a single dose of rose hip extract immediately prior to a C-section helps to reduce pain and the need for pain medications after surgery.
Insufficient evidence to rate effectiveness for...
- Aging skin. Early research shows that taking rose hip powder helps to reduce wrinkles and improve skin quality in aging adults.
- Menstrual cramps (dysmenorrhea). Early research shows that taking rose hip extract might help to reduce pain from menstrual cramps.
- Obesity. Early research shows that taking rose hip powder mixed with apple juice does not affect weight or blood sugar levels in people who are obese. But it might slightly reduce cholesterol and blood pressure.
- Rheumatoid arthritis (RA). Early research shows that taking rose hip by mouth improves some symptoms of RA.
- Infections of the kidney, bladder, or urethra (urinary tract infections or UTIs). Early research shows that taking rose hip powder after a C-section might lower the chance of having bacteria in the urinary tract. But it doesn't seem to prevent UTI symptoms.
- Sexual problems that prevent satisfaction during sexual activity.
- Boosting the immune system.
- Common cold.
- Enlarged prostate (benign prostatic hyperplasia or BPH).
- Flu (influenza).
- High blood pressure.
- High levels of cholesterol or other fats (lipids) in the blood (hyperlipidemia).
- Pain due to pressure on the sciatic nerve (sciatica).
- Problems of the vagina or uterus.
- Stomach and intestina problems.
- Stretch marks.
- Vitamin C deficiency.
- Other conditions.
How does it work?
Are there safety concerns?
When applied to the skin: There isn't enough reliable information to know if rose hip is safe or what the side effects might be.
Special precautions & warnings:Pregnancy and breast-feeding: There isn't enough reliable information to know if rose hip is safe to use as medicine when pregnant or breast-feeding. Stay on the safe side and stick to food amounts.
Kidney stones: In large doses, rose hip might increase the chance of getting kidney stones. This is due to the vitamin C in rose hip.
Are there interactions with medications?
- Aluminum is found in most antacids. Rose hips contain vitamin C. Vitamin C can increase how much aluminum the body absorbs. But it isn't clear if this interaction is a big concern. Take rose hip two hours before or four hours after antacids.
- Rose hip contains vitamin C. Vitamin C can increase how much estrogen the body absorbs. Taking rose hip along with estrogen can increase the effects and side effects of estrogens.
Some estrogen pills include conjugated equine estrogens (Premarin), ethinyl estradiol, estradiol, and others.
- Rose hip might have an effect like a water pill or "diuretic." Taking rose hip might decrease how well the body gets rid of lithium. This could increase how much lithium is in the body and result in serious side effects. Talk with your healthcare provider before using this product if you are taking lithium. Your lithium dose might need to be changed.
- Medications for cancer (Alkylating agents)
- Rose hip contains vitamin C, which is an antioxidant. There is some concern that antioxidants might decrease the effectiveness of some medications used for cancers. But it is too soon to know if this interaction occurs.
Some of these medications include cyclophosphamide, chlorambucil (Leukeran), carmustine (Gliadel), busulfan (Myleran), thiotepa (Tepadina), and others.
- Medications for cancer (Antitumor antibiotics)
- Rose hip contains vitamin C which is an antioxidant. There is some concern that antioxidants might decrease the effectiveness of some medications used for cancers. But it is too soon to know if this interaction occurs.
Some of these medications include doxorubicin (Adriamycin), daunorubicin (DaunoXome), epirubicin (Ellence), mitomycin (Mutamycin), bleomycin (Blenoxane), and others.
- Medications that slow blood clotting (Anticoagulant / Antiplatelet drugs)
- Rose hip contains a chemical that might cause blood to clot. Taking rose hip along with medications that slow clotting might decrease how well these medications work.
Some medications that slow blood clotting include aspirin, clopidogrel (Plavix), dalteparin (Fragmin), enoxaparin (Lovenox), heparin, ticlopidine (Ticlid), warfarin (Coumadin), and others.
- Warfarin (Coumadin)
- Warfarin (Coumadin) is used to slow blood clotting. Rose hip contains vitamin C. Large amounts of vitamin C might decrease the effectiveness of warfarin (Coumadin). Decreasing the effectiveness of warfarin (Coumadin) might increase the chance of clotting. Be sure to have your blood checked regularly. The dose of your warfarin (Coumadin) might need to be changed.
- Aspirin is removed from the body in the urine. Some scientists have raised the concern that vitamin C might decrease how much aspirin is removed in the urine. Rose hip contains vitamin C. There is concern that taking rose hip could increase the chance of aspirin-related side effects. But research suggests that this is not an important concern, and that the vitamin C in rose hip does not interact in a meaningful way with aspirin.
Are there interactions with herbs and supplements?
- Rose hip and acerola both contain high levels of vitamin C. Don't take both together. This might give you too much vitamin C. Adults should not take more than 2000 mg of vitamin C per day.
- Vitamin C
- Rose hip contains vitamin C. Taking rose hip with vitamin C supplements might increase the chance of side effects from vitamin C. Adults should not take more than 2000 mg of vitamin C per day.
Are there interactions with foods?
- There are no known interactions with foods.
What dose is used?
- For osteoarthritis: 2.5 grams of rose hip powder (LitoZin/i-flex, Hyben Vital) has been taken twice daily for 3 months. 40 mL of a specific combination product containing rose hip fruit puree 24 grams, stinging nettle 160 mg, devil's claw 108 mg and vitamin D 200 IU (Rosaxan, Medagil Gesundheitsgesellschaft) has been taken daily for 3 months.
- For pain after surgery: 1.6 grams of rose extract has been taken 15 minutes before surgery.
