Harpagophytum procumbens
Despite its sinister name, devil’s claw is one of the better-studied herbal remedies for joint and back pain. It comes from the dry savannas of southern Africa and has been used there for generations; in Europe it is a common choice for osteoarthritis and chronic lower back pain.
What is devil’s claw?
The plant takes its name from its fruit, which is covered in hooked “claws” that catch in the fur of passing animals. The medicinal part is the secondary storage root. Its key compound is harpagoside, which has anti-inflammatory and pain-relieving effects.
Health benefits of devil’s claw
1. Anti-inflammatory effects
Devil’s claw inhibits several inflammatory messengers in the body. It is used for degenerative joint conditions such as osteoarthritis and for rheumatic complaints.
2. Pain relief for joints and back
Clinical studies show that standardized extracts (providing around 50–60 mg of harpagoside a day) can reduce pain in osteoarthritis of the hip and knee and in chronic lower back pain. In some trials the effect was comparable to that of conventional anti-inflammatory drugs, though the studies are generally small. It works gradually, over two to four weeks.
3. Better mobility
By easing pain and stiffness, devil’s claw can improve mobility, especially in the morning.
4. Appetite and digestion
In low doses, its bitter substances stimulate the appetite and digestive juices – a traditional use in African folk medicine.
How to use devil’s claw
- Tea from the root – one teaspoon per cup of water, boil for five minutes and steep for ten; one to two cups a day (very bitter).
- Tablets and capsules – standardized extracts are the form used in studies.
- Gels and creams – for local muscle and joint pain.
Safety
Devil’s claw can cause digestive upset and is not suitable for people with stomach or duodenal ulcers or gallstones. Avoid it during pregnancy. It may interact with blood thinners, diabetes medication and some heart medicines, so talk to your doctor before using it alongside other drugs.
Worth knowing
- The hooks on the fruit are so effective that they can injure grazing animals.
- In southern Africa, the root was traditionally used for fever, digestive complaints and pain.
- Wild harvesting is regulated in several countries to protect the plant.
Summary
Devil’s claw is a useful herbal option for osteoarthritis and chronic back pain, with reasonable clinical evidence for standardized extracts. Give it a few weeks to work, and check with your doctor if you take other medication.
