Devil’s claw is a plant of the sesame family, Harpagophytum procumbens, whose tuberous roots are used in traditional medicine for stimulating digestion and easing joint pain. Native to the Kalahari regions of southern Africa, it takes its name from the hooked, claw-like seed pods. The dried root contains bitter iridoid glycosides, chiefly harpagoside, credited with anti-inflammatory effects, and it is sold in Europe as a herbal remedy for rheumatic complaints and loss of appetite. Evidence for the digestive claims is traditional rather than clinical, and the bitterness itself likely explains the appetite-stimulating reputation — bitter compounds reflexively increase saliva and gastric secretions. As a food supplement it sits in the grey zone of herbal regulation: long folk use, modest trial data, and a need for quality control against adulteration.
