Analgesic and anti-inflammatory effects of ethanolic extract of Thymus daenensis Celak in mice

The use of analgesic and anti-inflammatory medications is indispensable in clinical medicine. On the other hand, the increasing use of chemical drugs has several side effects that can sometimes be more dangerous than the disease itself. Therefore, research on the medicinal properties of plants to explore the effects of drugs with similar or even better than chemical drugs with fewer side effects is of great importance. In this research, analgesic and anti-inflammatory effects of Thymus daenensis Celak were investigated. For this purpose, 75 male mice weighing approximately 20-30 g were divided into 15 groups of 5 mice each. Writhing and formalin tests were applied to study analgesic effects and Xylene test was used to examine the anti-inflammatory effects. Extract at doses of 400, 600 and 800 mg/kg was tested. Saline solution and morphine (10 mg/Kg) were used in analgesic experiment and dexamethasone (10 mg/ kg) was used for anti-inflammatory experiment as positive group. Data were analyzed by SPSS software and mean comparisons were performed by Duncan’s Multiple Range Tests. According to the results, ethanolic extract of Thymus daenensis showed analgesic effects in Writhing test. Analgesic effects were not significant in the first phase of formalin test but it was significant in the second phase. Ethanolic extract of Thymus daenensis showed antiinflammatory effects at dose of 800 mg/kg-1. The conclusion is that analgesic effects of ethanolic extract of Thymus daenensis probably are caused by para cymene, -β-caryophyllene, carvacrol and especially thymol. Increasing doses and study on anti-inflammatory effects through other tests are needed for final confirmation of anti-inflammatory effects of Thymus daenensis.
