The crude extract of Sterculia tragacantha was subcutaneously infiltrated at the scrotum and left flank of West African dwarf goat prior to orchidectomy and non invasive flank procedures respectively. To assess the local anaesthetic efficacy of the extract post orchidectomy, the pain threshold, changes in vital parameters and blood glucose were monitored. Post flank infiltration, the durations of local anaesthesia, degree of analgesia and distances of tissue diffusion of the extract were monitored. Data obtained in the extract group were compared with those of lignocaine group and a control group. Mean heart rate (HR) of the extract group were significantly (p
