Evaluation of anti-inflammatory potential of the multidrug herbomineral formulation in male Wistar rats against rheumatoid arthritis.
BACKGROUND
Immunological and inflammatory mechanisms, which may play a role in a number of disorders like rheumatoid arthritis (RA). Ancient ayurvedic physicians had developed certain dietary and therapeutic measures to arrest or prevent these disorders.


OBJECTIVE
Rheuma off gold (RG) is a herbomineral formulation recommended by ayurvedic medical practitioners for treatment of RA. This study was carried out to lend scientific evidence to the efficacy claim for RG in the management of RA in folklore medicine.


METHODS
Arthritis was induced by complete Freund's adjuvant. Treatment with formulation 100 mg/kg and dexamethasone 2 mg/kg was given to rats intragastrically once a day from day 1 to day 21 and after which estimation of physical, biochemical, and hematological parameters were carried out.


RESULTS
Treatment of formulation to adjuvant induced arthritic animal showed statistically significant (P < 0.05) improvement in physical parameters like arthritic index, paw edema, paw thickness as well as reduction of inflammatory markers like C-reactive protein, serum rheumatoid factor, erythrocyte sedimentation rate. The treatment also produced statistically significant (P < 0.05) increase in hemoglobin percent and improvement in splenomegaly and thymus index. In the histopathological examination, ameliorative effect of formulation was observed in hyperplasia of synovium, pannus formation, and destruction of the joint space.


CONCLUSIONS
The results obtained in experiments indicated that the formulation significantly inhibited the adjuvant-induced arthritis which was comparable to dexamethasone and had preferable anti-inflammatory effect without significant side effect. Thus, the formulation may be a potential preventive or therapeutic candidate for the treatment of chronic inflammation and arthritis.
