BACKGROUND: The herb devil's claw (Harpagophytum procumbens) is a traditional south African anti-inflammatory remedy for pain and has been used in Europe to relieve pain from osteoarthritis over the past 50 years.
RESEARCH: Researchers treated patients with low-back pain with either 60 mg of devil's claw or 12.5 mg rofecoxib (Vioxx(, a leading COX-2 inhibitor prescription). For six weeks, forty-three of the patients took the herb, while 36 took the prescription medication. The patients' degree of pain was measured using standard clinical tests at baseline, 4 weeks and 6 weeks.
RESULTS: After six weeks, 18 of the patients taking the herb and 12 patients taking rofecoxib reported more than a 50 percent reduction in pain. By the end of the study, 10 of the patients taking the herb reported no pain and did not require any supplemental pain-reducing medication, compared with only five of the patients taking rofecoxib. There were no differences in reported side effects between the groups.
IMPLICATIONS: This study suggests that the anti-inflammatory herb devil's claw may be at least as effective in relieving pain as the leading COX-2 inhibitor prescription, rofecoxib.
