Evaluating the Efficacy of a Polyherbal Formulation in Ameliorating Arthritis Induced by Complete Freund’s Adjuvant

Abstract

Background: This study investigates the antiarthritic potential of a polyherbal formulation (PHF) comprising extracts from Tinospora cordifolia, Rosa damescena, and Acacia leucoploea in a rat model of rheumatoid arthritis (RA). RA is a chronic autoimmune disorder with debilitating consequences. PHF's impact on joint inflammation, bone degradation, and cartilage preservation were evaluated. Methods: Arthritis was induced using complete Freund’s adjuvant (CFA), and animals were treated with PHF (200 and 400 mg/kg), prednisolone, or control treatments for 28 days. Parameters including body weight, paw volume, arthritis severity score, hematological parameters, serum markers (creatinine, ALP, total proteins), cytokine levels (IL-1β, IL-6, TNF-α, IL-10), and radiographic changes were assessed. Results: CFA-treated rats exhibited significant body weight loss, paw edema, increased arthritis severity scores, altered hematological parameters, and elevated serum markers compared to normal controls. PHF treatment at both doses mitigated body weight loss, reduced paw edema, and improved arthritis severity scores. Hematological changes induced by CFA were also attenuated by PHF treatment. Serum creatinine, ALP, and total protein levels, elevated in CFA-treated rats, were significantly improved by PHF. Furthermore, PHF modulated cytokine levels, decreasing IL-6, IL-1β, and TNF-α while increasing IL-10. Radiographic analysis displayed reduced joint damage in PHF-treated rats compared to CFA controls. Conclusion: This comprehensive investigation highlights PHF's potential to mitigate the inflammatory processes associated with RA, as evidenced by improved clinical, hematological, and biochemical parameters. The study underscores the promise of traditional botanical compounds in managing RA and suggests PHFs as novel therapeutic options. Further mechanistic studies are warranted to elucidate the exact pathways involved.
