Natural remedies for joints and inflammation

Direct answer
The best-supported supplements for joint pain are concentrated curcumin for knee osteoarthritis and willow bark extract for short flare-ups of low back pain, both rated 3 (moderate), and in both cases the trials are short and the benefit is modest or uncertain. For most people with knee osteoarthritis, exercise has a larger evidence base than any supplement here. The caution that matters most is that curcumin has rare reports of liver injury and willow bark is a salicylate, related to aspirin.

Quick picks
Rated 3 for knee osteoarthritis pain: a 2021 meta-analysis of 16 trials (1,810 adults, up to 16 weeks) found less pain than placebo (SMD -0.82), but results varied widely between trials and a 2026 review rated the methods of the pooled reviews extremely low quality.
Gentlest optionGingerRated 2 for knee osteoarthritis pain: seven pooled trials showed a small drop in pain, but the reviewers called the evidence insufficient because the trials were poor quality. The main cautions are pregnancy (the EU regulator prefers avoiding it) and warfarin.
Traditional favouriteDevil's clawRated 2 for low back pain and for osteoarthritis. The Cochrane review found low-quality evidence of short-term pain relief at 50 to 100 mg harpagoside a day, and the osteoarthritis results are mixed.
Talk to a doctor first if…
Who should avoid
Pregnancy and breastfeeding are on the avoid list for curcumin, turmeric, willow bark, devil's claw and nettle leaf, and under-18s should avoid willow bark (Reye's syndrome risk), devil's claw and turmeric. Do not use willow bark if you are allergic to aspirin, other salicylates or NSAIDs, or have an active stomach ulcer, and devil's claw is also contraindicated with an active stomach or duodenal ulcer. Avoid curcumin and turmeric if you have liver disease, and see a doctor first for joint pain with swelling, redness or fever.
Known interactions
Willow bark may increase the effect of anticoagulants such as coumarin derivatives, and taking it with aspirin or other NSAID painkillers is not recommended without medical advice (both rated 2, caution). Ginger, devil's claw, curcumin and omega-3 have lower-rated (severity 1) reports or plausible concerns with blood thinners, so ask a pharmacist before adding any of them to warfarin or antiplatelet drugs.
Before you reach for an ingredient
For knee osteoarthritis, exercise, and weight loss if you are overweight, have larger trial evidence than any supplement here, although the benefits are modest.
- Exercise for knee osteoarthritis: a 2024 Cochrane review of 139 trials (12,468 people) found low-to-moderate certainty evidence that exercise probably improves pain, physical function and quality of life in the short term, with no difference between types of exercise. The reviewers say the benefit may not reach a clinically important size, and most trials were not blinded.6
- Weight loss with exercise: in overweight or obese adults with knee osteoarthritis, a 2019 meta-analysis found diet alone did not reduce pain (SMD -0.13, 95% CI -0.37 to 0.10), while diet combined with exercise reduced it moderately (SMD -0.37); both improved physical function.7
Questions people ask
Does turmeric help arthritis?
Concentrated curcumin extracts have reduced knee osteoarthritis pain more than placebo in short trials (rated 3), but plain turmeric powder or the spice is rated only 2 because the trials tested extracts. Reviews rate the certainty as low, and there are rare reports of serious liver injury with supplements.
Is willow bark the same as aspirin?
Willow bark contains salicin, a salicylate related to aspirin, so the same cautions apply: it is not suitable if you are allergic to aspirin, under 18, or taking anticoagulants or NSAIDs without medical advice. A small study found it reduced platelet clotting far less than low-dose aspirin.
Can cherry juice prevent gout attacks?
Not reliably. An observational study linked eating cherries to fewer attacks, but a 28-day randomised trial in people with gout found no effect of tart cherry concentrate on urate or flares (rated 2). Do not use it instead of prescribed gout treatment.
Does fish oil help joint pain?
In rheumatoid arthritis, a 2024 meta-analysis of 23 placebo-controlled trials found a small, statistically uncertain effect on pain (SMD -0.16, 95% CI -0.40 to 0.09), rated 2. We found no osteoarthritis review we could read, so the rating covers rheumatoid arthritis only.
