Topical Herbal Gel: Preparation and In Vivo Antiarthritic Activity Against Complete Freund's Adjuvant Induced Arthritis in Rats

Terminalia tomentosa bark belongs to the family Combretaceae. The plant bark is astringent and useful in the treatment of ulcers, vata, fractures, hemorrhages, bronchitis, and diarrhea. Phytochemical investigation of T. tomentosa bark confirms the presence of flavonoids, polyphenols, and tannins. The plant has not been investigated for its anti-inflammatory and antiarthritic activity. The present study was undertaken to explore its possible anti-inflammatory and antiarthritic activity. Anti-inflammatory activity of alcoholic and aqueous extracts of the bark was assessed by in vivo methods. In vivo antiarthritic potential of the extracts was evaluated by Complete Freund’s Adjuvant (CFA) induced arthritis in Wistar rats. Our findings showed that the alcoholic and aqueous extracts exhibited anti-inflammatory activity at 500 mg/kg oral dose in carrageenan-induced hind paw edema and carrageenan-induced air pouch inflammation models. We also found alcoholic as well as aqueous extracts of the bark restored the altered blood and serum parameters caused by the Complete Freund’s Adjuvant-induced arthritis in Wistar rats. This study shows that the T. tomentosa bark extracts possess anti-inflammatory activity and have pronounced effects on adjuvant arthritis also. Future studies are necessary to provide deeper insight into the exact mechanism of the action of anti-inflammatory and antiarthritic activity of T. tomentosa.

The present study was commenced to evaluate the anti-arthritic effect of 70% methanol extract and n-butanol and aqueous fractions of Berberis calliobotrys using both in vitro and in vivo arthritis models. Extract and fractions were investigated in vitro for inhibition of protein (bovine serum and egg albumin) denaturation and human red blood cell membrane stabilization. In vivo anti-arthritic activity of extract and fractions at 50, 100 and 200 mg/kg was assessed using turpentine oil and formaldehyde-induced arthritis, while, 200 mg/kg dose was evaluated against complete Freund’s adjuvant-induced arthritis. B. calliobotrys produced significant (p<0.001) dose dependent inhibition of protein denaturation and human red blood cell membrane stabilization. In turpentine oil, formaldehyde and complete Freund’s adjuvant-induced arthritis models, B. calliobotrys significantly (p<0.001) reduced joint and paw swelling. B. calliobotrys markedly improved body weight, hematology profile, radiological and histopathological parameters in complete Freund’s adjuvant model. It could be concluded that B. calliobotrys holds anti-arthritic potential, supporting its traditional use in treatment of rheumatoid arthritis.
