Devil’s claw (also known as harpagophytum procumbens) is an herb used by some in the treatment of low back pain. It comes from a plant in South Africa and has several medicinal uses.
Scientists are trying to unravel the mechanisms behind treatment with herbal supplements like Devil’s claw. This plant (along with many others) has been the subject of many biochemical research projects.
Review of current studies show that a daily dose of 50 mg of Devil’s claw reduced back pain more than placebo (sugar pill with no known benefit). One study comparing Devil’s claw with an antiinflammatory drug (rofecoxib) showed that Devil’s claw worked just as well as the drug.
Devil’s claw can cause GI upset such increased stomach acid. Blood sugar problems can occur, decreased blood pressure, and changes in how drugs are used in the body. The effects are minimal and temporary. Only a small number of people have any side effects or adverse response to this herb.
