The plant was taken from the commercial source. The dried leaves powder of MO was macerated at room temperature in 70% ethanol (1 g/10 ml) and extracted for a week. On the seventh day, the ethanolic extract was refined and the extract was evaporated under reduced pressure to remove the ethanol. The dry extract was suspended in the normal saline and thus alcoholic extract of MO was prepared. We have previously shown that most effective dose of MO in the animal model of SCI is 150 mg/kg. So, in this study, we administered 150 mg/kg of MO (Pereira et al., 2009; Hosseini et al., 2015).
