Rosehips
Also known as: Rosa canina, Rosehip, Rose Hip, Dog Rose
Overview
Rose hips are the pseudo fruits of the *Rosa canina* plant, a rich source of bioactive compounds like flavonoids, carotenoids, and fatty acids. With a history spanning over 2,000 years in traditional medicine, rose hips are primarily recognized for their anti-inflammatory and antioxidant properties. They are commonly used for the symptomatic treatment of osteoarthritis, with emerging interest in their potential for wound healing and managing other inflammatory conditions. Available in various forms, including powders, extracts, and teas, standardized rosehip powder is the most studied form. Research indicates that rose hips can reduce pain and improve joint function in osteoarthritis patients. The quality of available evidence is generally good, with several randomized controlled trials supporting its efficacy, though further long-term studies are warranted to fully establish its benefits and safety.
Benefits
Rosehip powder has demonstrated a small to moderate effect on pain reduction in osteoarthritis patients, as evidenced by a meta-analysis of three RCTs (effect size 0.37, 95% CI 0.13 to 0.60, p=0.0019). It has also been shown to reduce the use of rescue medication (effect size 0.28, 95% CI 0.05 to 0.51, p=0.018) and increase the likelihood of patients responding to treatment (OR 2.19, 95% CI 1.38 to 3.48, p=0.00089). Secondary benefits include improvements in stiffness, mood, wellbeing, and sleep quality in osteoarthritis patients. Emerging evidence suggests potential for improving postsurgical scars, though more research is needed. These benefits are primarily observed in individuals with osteoarthritis, particularly of the knee and hip, with benefits typically seen within 3-4 months of treatment.
How it works
Rose hips exert their beneficial effects through anti-inflammatory and antioxidant pathways. The bioactive compounds, particularly flavonoids and fatty acids, play a crucial role in these processes. Rose hips interact with the musculoskeletal and immune systems, reducing inflammation and oxidative stress, which contributes to the alleviation of osteoarthritis symptoms. Specifically, they have been shown to reduce plasma CRP (C-reactive protein) levels, indicating an anti-inflammatory effect. While the exact mechanisms of absorption and bioavailability are not fully understood, standardized extracts used in clinical trials have proven effective in delivering these bioactive compounds.
Side effects
Rosehip powder is generally considered safe, with a high safety profile observed in clinical trials. Common side effects, occurring in more than 5% of users, include mild gastrointestinal discomfort and acid regurgitation, though these are not significantly different from placebo groups. Uncommon side effects, affecting 1-5% of users, include infrequent reports of frequent voiding, diarrhea, constipation, and mild urticaria. Rare side effects, occurring in less than 1% of users, are not reported in the available literature. While significant drug interactions are not evident, caution is advised when using rose hips with other anti-inflammatory medications. Individuals with known allergies to rose hips or its components should avoid its use. The safety and efficacy in pregnant or breastfeeding women, children, and individuals with severe medical conditions have not been extensively studied and should be approached with caution.
Dosage
The minimum effective dose of standardized rosehip powder is typically around 2.5-5 grams per day. The optimal dosage range is generally 5 grams per day, taken in divided doses. While there is no established maximum safe dose, doses up to 10.5 grams per day have been used in some studies without significant adverse effects. The timing of administration does not appear to be critical, but consistent daily use is recommended for optimal effects. Standardized rosehip powder is the most studied and recommended form. While not well-studied, the absorption of rose hip compounds may be enhanced when taken with food. No specific cofactors are required for efficacy, but a balanced diet and adequate hydration are recommended for general health.
FAQs
Is rosehip safe to use?
Rose hips are generally safe, but individuals should be aware of potential mild gastrointestinal side effects and rare allergic reactions. Discontinue use if you experience any adverse effects.
How should I take rosehip for best results?
Consistent daily use of 5 grams of standardized rosehip powder is recommended for optimal effects. You can divide the dose and take it with meals.
How long does it take to see results from rosehip?
Patients can expect a moderate reduction in pain and improvements in stiffness and wellbeing within 3-4 months of consistent treatment. Individual results may vary.
Can rosehip cure osteoarthritis?
Rose hips are not a cure for osteoarthritis but can be a useful adjunctive treatment for symptom management. Consult with your healthcare provider for a comprehensive treatment plan.
