Abstract
This study evaluated a new herbal preparation, HemoHIM, for its antiinflammatory activity against carrageenan-induced edema, the formation of granulation tissues by cotton pellet and experimental colitis by 2,4,6-trinitrobenzene sulfonic acid (TNBS). The HemoHIM was prepared by adding its ethanol-insoluble polysaccharide fraction to the total water extract of Angelica Radix, Cnidii Rhizoma and Paeonia Radix. The preparation (4 mg of solids/mL of drinking water, p.o., 50-100 mg/kg of body weight, i.p.) produced a dose-related inhibition of carrageenan-induced paw edema and cotton pellet-induced granuloma in rats. In addition, HemoHIM also reduced the degree of TNBS-induced colitis and improved the gross and histological changes such as thickening, dilatation, ulceration, and infiltration by polymorphonuclear leukocytes and multiple erosive lesions. These results demonstrate that the HemoHIM has a potent antiinflammatory effect.
