    The present study aimed to evaluate the analgesic and anti-inflammatory activity of the hydroalcoholic extract of leaves and stems of Leucheria daucifolia (D. Don.) Crisci “Churoq wasin”. For the analgesic activity, the model of abdominal writhing induced by 0.8% acetic acid was employed; 49 mice were used, and the evaluated groups were: negative control (distilled water), positive control (0.8% acetic acid), hydroalcoholic extract at 50, 100 and 200 mg/kg, compared with paracetamol 300 mg/kg and tramadol 40 mg/kg. For the anti-inflammatory effect, the auricular edema method was used with an irritant agent (6% xylene diluted in acetone) applied to the mouse auricle. A total of 49 albino mice were used, and the study groups were: vaseline cream, creams prepared with the hydroalcoholic extract at 0.5, 1 and 2%, compared with diclofenac 1% cream and hydrocortisone 1% cream. The results show that the hydroalcoholic extract of leaves and stems of Leucheria daucifolia (D. Don.) Crisci “Churoq wasin” at a dose of 100 mg/kg presents analgesic activity with an inhibition percentage of writhing of 62%, not surpassing tramadol (86%) but comparable to paracetamol (76%). Regarding anti-inflammatory activity, the cream with 2% extract presented an inhibition percentage of inflammation of 48.7%, which is comparable to hydrocortisone 1% and diclofenac 1%. It was confirmed that the hydroalcoholic extract possesses both analgesic and anti-inflammatory activity in mice.
