Low Back Pain and Sciatica and Devil's Claw

Read more about Devil's Claw.

Effect of Devil's Claw on Low Back Pain and Sciatica

Devil's claw has been used for the treatment of osteoarthritis, and has been tried for back pain as well. When the pain is arthritic in nature, is likely the best time to use devil's claw for the treatment of back pain or sciatica.

Research Evidence on Devil's Claw

A double-blind, placebo-controlled study of 197 individuals with chronic back pain found devil's claw only marginally effective at best.38

Similarly poor results were seen in an earlier 4-week, double-blind, placebo-controlled study of 118 individuals with acute back pain.39

However, a 4-week, double-blind, placebo-controlled study of 63 people with mild to moderate chronic muscular tension in the neck, back, and shoulders did find some benefit.27

Side Effects and Warnings

#Safety Issues

Devil's claw appears to be safe, at least for short-term use. In one study, no evidence of toxicity emerged at doses many times higher than recommended. ^[1] In a review of 28 clinical trials dating back 20 years, researchers found no instances where adverse effects were more common than those associated with a placebo. Minor adverse effects, most gastrointestinal in nature, occurred in roughly 3% of patients. ^[2] Devil's claw is not recommended for people with ulcers. A 6-month open study of 630 people with arthritis showed no side effects other than occasional mild gastrointestinal distress. According to one case report, the herb devil's claw might increase the potential for bleeding while taking warfarin . ^[4] Safety in young children, pregnant or nursing women, or those with severe liver or kidney disease has not been established.

#Interactions You Should Know About

If you are taking:

  • Blood-thinning medications such as warfarin (Coumadin) or heparin : Devil's claw might enhance their effect, possibly producing a risk of bleeding.
