What is Devil's Claw?

Devil's claw is a native of South Africa, so named because of its rather peculiar appearance. Its large tuberous roots are used medicinally, after being chopped up and dried in the sun for 3 days.

Native South Africans used the herb to reduce pain and fever and stimulate digestion. European colonists brought devil's claw back home, where it became a popular treatment for arthritis.
