Effects of Methanol Fraction from Leaves ofSchinus terebinthifoliusRaddi on Nociception and Spinal-Cord Oxidative Biomarkers in Rats with Neuropathic Pain

We determined the antioxidant potential of fractions obtained from leaves of Schinus terebinthifolius , a medicinal plant known in Brazil as aroeira, to select the fraction with the best yield and antioxidant performance. These qualities were found in the methanol fraction (MeF), which was administered intraperitoneally (20 mg/kg/day) for 3 and 10 days to rats with chronic constriction injury (CCI) of the sciatic nerve, a model of neuropathic...
