Harpagophytum, commonly known as Devil’s Claw, is a distinctive plant that boasts a unique appearance and a rich history of medicinal use. This botanical description will provide you with a detailed insight into the key characteristics of Harpagophytum, helping you understand its morphology and growth habits.
Harpagophytum belongs to the family Pedaliaceae and is scientifically known as Harpagophytum procumbens. This perennial herbaceous plant is native to the arid regions of southern Africa, where it thrives in sandy and rocky soils.
Devil’s Claw is characterized by its low-growing and spreading growth habit. It typically reaches a height of about 20 to 50 centimetres (8 to 20 inches) and spreads horizontally along the ground.
The plant’s stems are prostrate, meaning they lie flat on the ground, while the leaves emerge in opposite pairs along these stems.
The leaves of Harpagophytum are pinnate, which means that multiple leaflets are arranged along a central stalk or rachis.
Each leaf typically consists of 3 to 5 leaflets, with each leaflet being ovate to lanceolate in shape. The leaves are deeply lobed or serrated along the margins, providing an interesting visual texture.
Devil’s Claw produces eye-catching tubular flowers that are usually a shade of mauve, pink, or purple. These flowers emerge on long stalks from the leaf axils.
The corolla of the flower is bilabiate, featuring two distinct lips, with the upper lip having two lobes and the lower lip having three lobes.
One of the most distinctive features of Devil’s Claw is its fruit, which gives the plant its common name. The fruit is a woody capsule that is covered in hooked spines, resembling claws or hooks. These hooked structures aid in seed dispersal, as they can attach to passing animals and be carried to new locations.
The secondary tubers of Devil’s Claw are the part of the plant that holds its medicinal properties. These tubers are large, fleshy structures that store nutrients and water. They have a gnarled and tuberous appearance, contributing to the plant’s unique and intriguing character.
Devil’s Claw is well adapted to the arid climates of southern Africa, particularly regions such as Namibia, Botswana, and South Africa.
It thrives in sandy and rocky soils, often growing in savannahs and grasslands. The plant’s ability to survive in such harsh conditions is a testament to its resilience.

Scientific Evidence and Case Studies on Harpagophytum (Devil’s Claw)
1. Chrubasik et al. (2003): A randomized double-blind study compared a proprietary Harpagophytum extract (Doloteffin) with Vioxx for low back pain. The study found that Devil’s Claw reduced pain as effectively as the NSAID, with fewer side effects, suggesting its potential as a safer alternative for pain management (Chrubasik, S., Model, A., Black, A., et al., 2003).
2. Chantre et al. (2000): This multicenter, double-blind study compared Harpagophytum extract (Harpadol) with diacerhein in patients with knee or hip osteoarthritis. Both groups showed similar improvements in pain and function, but the Devil’s Claw group used fewer NSAIDs and reported better tolerance, indicating its efficacy for osteoarthritis (Chantre, P., Cappelaere, A., Leblan, D., et al., 2000).
3. Chrubasik et al. (2005): A 1-year follow-up study on Doloteffin for low back pain and osteoarthritis showed sustained pain relief and improved function by weeks 4 and 8, with minimal adverse effects, supporting its long-term use for chronic pain (Chrubasik, S., Kunzel, O., Thanner, J., et al., 2005).
4. Inaba et al. (2010): An animal study demonstrated that harpagoside significantly suppressed cytokine production in mouse macrophages, supporting its anti-inflammatory effects. This suggests a mechanism for Devil’s Claw’s benefits in inflammatory conditions (Inaba, K., Murata, K., Naruto, S., et al., 2010).
5. Moreau et al. (2021): A randomized controlled trial in dogs with osteoarthritis found that a Harpagophytum extract (harpagoside >2.7%) improved clinical signs and peak vertical force compared to placebo, indicating potential veterinary applications (Moreau, M., Lussier, B., Pelletier, J. P., et al., 2021).
