Devil’s Claw for Arthritis, Sciatica, Osteoarthritis

Devil’s Claw for Arthritis/Harpagophytum also call grapple plant, wood spider and most commonly devil’s claw is a genus of plants in the sesame family, native to southern Africa. Plants of the genus owe their common name “devil’s claw” to the peculiar appearance of their hooked fruit. Several species of North American plants in genus Proboscidea and certain species of Pisonia are however also known by this name. Devil’s claw’s tuberous roots are used in folk medicine to reduce pain.

Devil’s Claw, is a genus of tuberiferous xerophytic plants native to southern Africa. Some of the taxa are appreciated for their medicinal effects and have been traditionally used to relieve symptoms of inflammation. The objectives of this pilot study were to investigate the antioxidant capacity and the content of total phenols, verbascoside, is verbascoside, and selected iridoids, as well as to investigate the capacity of various Harpagophytum taxa in suppressing respiratory burst in terms of reactive oxygen species produced by human neutrophils challenged with phorbol myristate acetate (PMA), opsonisedStaphylococcus aureus, and Fusobacterium nucleatum.

Devil's Claw for Arthritis

Indications of Devil’s Claw

Devil’s Claw was completely ineffective in reducing edema of the rat hindfoot induced by either lambda-carrageenan or Mycobacterium butyricum. At concentrations of up to 1 x 10(5) microgram/ml, Devil’s Claw was also ineffective as an in-vitro inhibitor of prostaglandin synthetase. These results indicate that Devil’s Claw lacks the anti-inflammatory properties possessed by all antiarthritic drugs of the nonsteroidal, anti-inflammatory analgesic type.

Preparations of the plant or its extracts, such as harpagoside – ^[rx] are presumed to have used in folk medicine and phytotherapy as an anti-inflammatory herbal drug or dietary supplement.^[rx] Although there is no accepted clinical evidence of its efficacy and bioavailability, limited effects were noted for treating lower back pain and osteoarthritis.^[rx]A Cochrane review of clinical research noted that devil’s claw seems to reduce low back pain more than placebo, although evidence was of moderate quality at best.^[rx]
Back pain – Taking devil’s claw by mouth seems to reduce low-back pain. Devil’s claw seems to work about as well as some non-steroidal anti-inflammatory drugs (NSAIDs).
Osteoarthritis – Taking devil’s claw alone or along with nonsteroidal anti-inflammatory drugs (NSAIDs) seems to help decrease osteoarthritis-related pain. Some evidence suggests that devil’s claw works about as well as diacerein (a slow-acting drug for osteoarthritis that is not available in the U.S.) for improving osteoarthritis pain in the hip and knee after 16 weeks of treatment. Some people taking devil’s claw seem to be able to lower the dose of NSAIDs they need for pain relief.
Rheumatoid arthritis (RA) – Early research suggests that taking devil’s claw extract by mouth might not improve RA.
