    The objective of the study was to determine the analgesic and anti-inflammatory activity of the ethanolic extract from the root of Taraxacum officinale Wigg, "dandelion," in mice. The root was macerated for 7 days in 70% ethanol. Solubility and qualitative analyses were performed, and the extract was determined to be soluble in polar solvents and to contain flavonoids and alkaloids. To determine the analgesic activity, the 0.8% glacial acetic acid-induced abdominal writhing model was used on 49 Balbin/C53/CNPB strain mice. The groups were a negative control (distilled water), a positive control (0.8% acetic acid), the ethanolic extract at 25, 50, and 100 mg/kg, and comparative standards of paracetamol (300 mg/kg) and tramadol (40 mg/kg). To determine the anti-inflammatory effect, the subplantar edema method was used, with dexamethasone (4 mg/kg) and diclofenac (50 mg/kg) as standard drugs. The evaluation of the extract's analgesic activity showed an effective dose of 100 mg/kg with 69% writhing inhibition. The anti-inflammatory activity was effective at a dose of 25 mg/kg, with an inhibition percentage evolving from 56% to 99% over a six-hour period.
