Comfortable movement is an important part of a dogs wellbeing, from enjoying a walk to stretching after a peaceful sleep.
Devils Claw is a botanical ingredient often found in supplements intended for joint comfort and mobility. Behind its unusual name is a southern African plant with a long history of traditional use.
But where does it come from, which part is used, and what do we know about its potential benefits for dogs?
What is Devils Claw?
Devils Claw is the common name associated with plants in the genus Harpagophytum, and closely related Harpagophytum Zeyheri.
These plants belong to the Pedaliaceae family, which also includes sesame. Harpagophytum procumbens is a perennial herb with creeping stems, lobed leaves and tubular flowers that are usually pink or purple.
Its striking name comes from its woody fruits, which have curved, hook-like projections. These hooks can catch on passing animals, helping to disperse the seeds.
The hooked fruit gives the plant its name, but the underground tubers are part used in root preparations.
Where does it come from?
Devils Claw grows in southern Africa, particularly in the dry, sandy environments associated with the Kalahari region. Its range includes countries such as Namibia, Botswana and South Africa.
Communities in this region have used the plant in traditional medicine for centuries. This knowledge contributed to its later introduction into herbal products elsewhere in the world.
The European Medicines Agency recognises the traditonal use of certain Devils Claw preparations for minor joint pain in adults.
Which part becomes the powder?
Devils Claw develops a primary root system with additional fleshy storage tubers growing from lateral roots. These are known as secondary tubers.
Root powder is produced by drying and grinding this tuberous material. Other preparations use extraction processes to concentrate selected compounds.
A whole root powder and a concentrated extract are different products. Their composition and strength can vary, so research findings and feeding amounts should not automatically be transferred between them.
How might it support joints?
One of the best-known constituents of Devils Claw is Harpagoside, a naturally occurring compound belonging to a group called iridoid glycosides.
Researchers have investigated harpagoside because of its effects on processes involved with inflammation. For example, a laboratory study using human cartilage cells found that it reduced the production of interleukin-6 , a signalling molecule involved in inflammatory responses.
The same study also investigated effects on an enzyme involved in cartilage breakdown. These findings help explain scientific interest in the plant.
Precautions before introducing Devils Claw
Human safety guidance identifies stomach and intestinal side effects with devils claw preparations and advises against use with active stomach or duodenal ulcers. It also highlights precautions around gallstones and insufficient safety information during pregnancy and breastfeeding.
Before feeding it, speak to your vet if your dog:
Has a history of stomach ulcers, digestive problems or gallbladder disease.
Takes medication, including anti-inflammatory painkillers.
Receives other herbal products or joint supplements.
Is young, pregnant, nursing or has an existing medical condition.
