Devil's claw (Harpagophytum procumbens), the Anti-Inflammatory Remedy

By Kyle J. Norton

Inflammation is the natural response of the immune system macrophages, the first line of defense in stimulating the production of inflammatory cytokines to protect our body against the infection caused by foreign microorganisms during the acute phase of body damage and injury.

Truly, the main focus of inflammation is to repair damage and injury.

Most cases of infection associated with inflammation are stopped at the acute phase. The wound or injury is slowly recovered.

However, overexpression of inflammatory cytokines in most cases can cause improper healing with scar formation or the death of nearby cells.

Any inflammation that lasts more than 8 weeks is considered chronic inflammation.

Believe it or not, worldwide, 3 of 5 death are results from chronic inflammatory diseases like stroke, chronic respiratory diseases, heart disorders, cancer, obesity, and diabetes.

In the US, chronic inflammatory diseases affect more than 50 million Americans each year.

Diseases associated with low-grade inflammation include diabetes and cardiovascular.

Conventionally, Nonsteroidal anti-inflammatory drugs (NSAIDs) are the most common medical drugs such as aspirin. ibuprofen in reducing inflammation associated with pain-relieving.

On finding a natural ingredient for the prevention and treatment of liver diseases, scientists investigated the prepared an extract of Euphrasia officinalis, a traditional folk medicine, to synthesize gold nanoparticles (EO-AuNPs) anti-inflammatory effects on lipopolysaccharide (LPS)-stimulated RAW 264.7 macrophages.

Devil's claw also known as the wood spider, is a plant of genus Harpagophytum in the family of Pedaliaceae, native to South Africa. 

The plant has been used as an herb in traditional and herbal medicine to treat fever, rheumatoid arthritis, skin, gallbladder, pancreas, stomach and kidneys conditions, etc.

According to tested analysis, the successful synthesis of AuNPs by E. officinalis showed significant anti-inflammatory activities detected by a model of LPS-induced upregulation of inflammatory mediators and cytokines.

More precisely, AuNPs by E. officinalis inhibited the levels of nitric oxide (NO), nitric oxide synthase (iNOS), tumor necrosis factor-α (TNF-α), IL-1β, and IL-6 in RAW 264.7 cells.

Furthermore, EO-AuNPs exhibited little cytotoxicity in RAW 264.7 cells at 100 µg/mL concentration after 24 hours.

Pretreatment with EO-AuNPs also significantly reduced the phosphorylation and degradation of inhibitor kappa B-alpha and inhibited the nuclear translocation of NF-κB p65 involved the production of pro-inflammatory cytokines.

Additionally, EO-AuNPs suppressed LPS-stimulated inflammation by blocking the activation of JAK/STAT pathway associated with cytokines and growth factors.

Based on the results, researchers suggest, "The synthesized EO-AuNPs showed anti-inflammatory activity in LPS-induced RAW 264.7 cells, suggesting they may be potential candidates for treating inflammatory-mediated diseases".


Taken altogether, Dandelion may be considered an anti-inflammatory remedy, pending to the confirmation of the larger sample size and multicenter human study.
