What is Devil's Claw?
Devil's Claw (Harpagophytum procumbens) is a medicinal plant native to southern Africa, particularly the Kalahari Desert regions of South Africa, Botswana, and Namibia. The name comes from its fruit, which has small hook-like projections resembling claws.
Active Component: The secondary root tubers contain iridoid glycosides, particularly harpagoside, which is responsible for most therapeutic effects.
Traditional Use: Indigenous peoples of southern Africa have used Devil's Claw for centuries to treat pain, fever, digestive issues, and various inflammatory conditions.
