Harpagophyte (Harpagophytum procumbens Pedaliaceae)

Other Names: Devil's Claw, Grapple Plant, Wood Spider

Native to southern Africa, Harpagophyte, commonly known as Devil's Claw, has been used for centuries to treat ailments ranging from indigestion and fever to skin conditions. Its name derives from the unique, claw-like appearance of its fruits. This creeping perennial produces striking dark red trumpet-shaped flowers during the summer.

Parts for Use

Tubers

1. Tubers, or thickened roots, are harvested in autumn, dried, and cut into small round pieces.
2. Used to prepare infusions, powders, drinking solutions, ointments, gels, and creams.
3. Only wild-growing plants are used in herbal medicines, raising concerns about the species' sustainability.

Ingredients

The primary active components are iridoids, constituting 0.5 to 3 percent of the dry drug, with harpagoside being the most active. Preparations should ideally contain 1.5 to 2 percent harpagoside for optimal efficacy. The plant also contains phytosterols and flavonoids.

Use in Treatment

Studies demonstrate that Harpagophyte can alleviate pain and, in some cases, improve mobility in individuals with osteoarthritis or degenerative rheumatism. Harpagoside and phytosterols provide anti-inflammatory properties, making it effective for milder forms of rheumatism. It is also used externally to relieve joint pain.

Cultivation

Harpagophyte is challenging to cultivate outside its native southern African habitat, relying primarily on wild harvesting.
