What Is It?

Devil’s claw is an herbacious African perennial plant, native to the Kalahari savanna of Southern Africa, the Namibian steppes, and Madagascar. [ii]   The plant lies flat on the ground, with long branches which extend to 1.5 metres in length.  [iii]    Devil’s claw root refers to the dried, secondary tubers of the plant, which are used medicinally, primarily in Africa and Europe.  [iv]   According to ESCOP the roots should contain not less than 1.0% of the compound harpagoside.  [v]   Devil’s claw root plays a valuable role in African folk medicine, where it has been used as a digestive tonic, for blood disorders, to reduce fever, as an analgesic, and to relieve various complaints during pregnancy.  [vi]

Medicinal History

In its origins in South Africa, Devil’s claw root was used for fever, stomach upsets and rheumatic disorders.  [x]   Its bitterness drew attantion to its usefulness for general digestive complaints.  [xi]  The root was also employed by African women to alleviate pain during pregnancy.  [xii]   Devil’s claw root was introduced to Western medicine by a South African farmer, G.H. Mehnert, who observed its broad uses among natives.  [xiii]   Devil’s claw root was first used in Europe in 1953, where it has enjoyed use for arthritic, liver, bile, kidney and bladder complaints, and allergies.  [xiv] 

 

Today Devils’ claw root is approved by Germany’s Commission E for loss of appetite, dyspepsia (indigestion), and supportive therapy of disorders of the locomotor system. [xv]   It is approved by ESCOP for Painful arthrosis, tendinitis, loss of appetite and dyspepsia.  [xvi]
