Abstract
In the present study the ethyl acetate extract of Rhododendron arboreum (Family: Ericaceae) was investigated for its anti-inflammatory and anti-nociceptive potential in animal models.Oral administration of Rhododendron arboreum extract (EERA) (100, 200 and 400 mg/kg) exhibited dose dependent and significant anti-inflammatory activity in arachidonic induced hind paw edema (p<0.01), cotton pellet granuloma model of inflammation (p<0.01) and Freund’s adjuvant-induced paw arthritis (p<0.01). A significant (p<0.05) anti-nociceptive activity was evidenced in mice, protection in acetic acid-induced writhing. EERA at the dose levels of 100,200 and 400 mg/kg exhibited significant (p<0.001) resistance against analgesymeter induced pain in mice. The hot plate reaction time was increased at a dose of 100, 200 and 400 mg/kg significantly (p<0.001).The present study justifies the anti-inflammatory and anti-nociceptive potential of Rhododendron arboreum.
