Description: Devil's claw is a perennial plant with tubers and many round to oval-shaped stems. The leaves have white, hairy undersides. Solitary, red to purple flowers, shaped like trumpets appear in spring followed by the fruit. The name devil's claw comes from the hooks that cover its fruits.

Plant Parts Used: Roots and tuber. The root is collected when the rainy season ends.

The major active ingredient is harpagoside and standardisation products can contain anything from 1-8.5% harpagoside.
