title: Anti-inflammatory and antinociceptive activity of Thymus pubescens extract.
abstract: Thymus pubescens is an aromatic and medicinal plant, which has been widely distributed in Iran. The anti-inflammatory and analgesic effects of the T. pubescens aerial parts methanol extract were studied at doses of 50-400 mg/kg i.p. using carrageenan-induced edema, formalin, hot plate and writhing tests. The extract produced a significant decrease in the degree of swelling, 3 h after carrageenan injection and caused graded inhibition of both phases of formalin-induced pain. Moreover, in the hot plate test, it significantly raised the pain threshold. While in the writhing test produced a significant decrease in the number of writhing in comparison with the control group (P<0.001). The results of pharmacological tests performed in the present study suggest that the extract of T. pubescens presents analgesic and anti-inflammatory effects.
