Devil's claw: properties and contraindications of the plant
Let's explore devil's claw, a plant native to south-eastern Africa that has been used for centuries to treat joint pain, including osteoarthritis.
The devil's claw plant
The Latin name, Harpagophytum procumbens, derives from the shape of the fruit, which is hard and covered in claws that would sometimes catch on the hooves of pack animals. This is why this plant, belonging to the Pedaliaceae family, was considered "diabolical" — hence the common name, "devil's claw".
Properties of devil's claw
Appearances can be deceiving. Even in ancient times, in its regions of origin — Namibia, South Africa and Botswana
— devil's claw was used by the Bushmen, Hottentot and Bantu tribes to aid digestion, treat digestive disorders, and as a fever reducer and tonic.
Discovered by Westerners in the early 1900s, the plant was introduced to Europe for therapeutic use only in 1953. Since then, several studies have demonstrated its effectiveness as an analgesic against rheumatic and joint pain (it protects cartilage). The parts used are the secondary lateral roots. The pharmacological action is due primarily to harpagoside, an iridoid substance (i.e. a glucoside, meaning a compound derived from glucose) with anti-inflammatory and analgesic properties.
Devil's claw for osteoarthritis
It is useful for treating rheumatic pain, osteoarthritis, and tendon and muscle inflammation. It has hypoglycaemic and cholesterol-lowering properties. Devil's claw is administered both as a decoction and as an extract, always under medical supervision, as it may cause stomach irritation if taken in excessive amounts; it can also be used topically in the form of an ointment.
For headaches caused by cervical osteoarthritis
It is an effective natural painkiller against cervical-related headaches. It can be taken as tablets or capsules, decoctions and herbal teas, mother tincture, glyceric macerate and ointment. For dosage, consult your trusted herbalist.
Can it be taken during pregnancy?
It stimulates uterine contractions and can bring on early labour, so it should be avoided during pregnancy.
Contraindications
Due to its hypoglycaemic action, it is not recommended for diabetics who are already taking medication for that purpose. Its use is also contraindicated for those suffering from gastritis and duodenal ulcers, as the plant stimulates gastric secretion. Devil's claw interacts with anticoagulant drugs.
