Healthy Response to Normal Joint Stress Bioactive Flavonoids and Phytosterols Devil’s Claw is native to the southern regions of Africa and gets its name from the hooks which cover its fruit. It has been traditionally used by tribal African peoples and more recently by Europeans and North Americans. Devil’s Claw is abundant in naturally occurring bioactive compounds including harpagoside, phytosterols, phenolic acids and flavonoids (kaempferol). Some studies suggest that these compounds may help to support joint comfort through their ability to promote a healthy response to typical everyday joint stress.
