Devil’s claw is an herb. The botanical name, Harpagophytum, means “hook plant” in Greek. This plant, which is native to Africa, gets its name from the appearance of its fruit, which is covered with hooks meant to attach onto animals in order to spread the seeds. The roots and tubers of the plant are used to make medicine.An Herb For Thought: Devil's Claw | DevilsClaw | An Herb For Thought Natural Health Natural Medicine Devil’s claw is used for “hardening of the arteries” (atherosclerosis), arthritis, gout, muscle pain (myalgia), back pain, tendonitis, chest pain, gastrointestinal (GI) upset or heart burn, fever, and migraine headache. It is also used for difficulties in childbirth, menstrual problems, allergic reactions, loss of appetite, and kidney and bladder disease.Some people apply devil’s claw to the skin for injuries and other skin conditions.

Effective for…

  • Decreasing pain from a kind of arthritis called 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 diacerhein (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. This evidence comes from a study that used a specific powdered devil’s claw root product (Harpadol, Arkopharma) containing 2% of the devil’s claw ingredient harpagoside (9.5 mg/capsule) and 3% total iridoid glycosides (14.5 mg per capsule). Another specific devil’s claw extract (Doloteffin, Ardeypharm) 2400 mg/day providing 60 mg/day of the harpagoside ingredient has also been used.
  • Back pain. Taking devil’s claw orally seems to lessen low-back pain.
