Rheumatoid arthritis is a chronic crippling disease, where protein‐based tumor necrosis factor‐alpha (TNF‐α) inhibitors show significant relief, but with potentially fatal side effects. A need for a safe, oral, cost‐effective small molecule or phyto‐pharmaceutical is warranted. BV‐9238 is an Ayurvedic poly‐herbal formulation containing specialized standardized extracts of Withania somnifera , Boswellia serrata , Zingiber officinale and Curcuma longa . The anti‐inflammatory and anti‐arthritic effects of BV‐9238 were evaluated for inhibition of TNF‐α and nitric oxide (NO) production, in lipopolysaccharide‐stimulated, RAW 264.7, mouse macrophage cell line. BV‐9238 reduced TNF‐α and NO production, without any cytotoxic effects. Subsequently, the formulation was tested in adjuvant‐induced arthritis (AIA) and carrageenan‐induced paw edema (CPE) rat animal models. AIA was induced in rats by injecting Freund's complete adjuvant intra‐dermally in the paw, and BV‐9238 and controls were administered orally for 21 days. Arthritic scores in AIA study and inflamed paw volume in CPE study were significantly reduced upon treatment with BV‐9238. These results suggest that the anti‐inflammatory and anti‐arthritic effects of BV‐9238 are due to its inhibition of TNF‐α, and NO, and this formulation shows promise as an alternate therapy for inflammatory disorders where TNF‐α and NO play important roles.
