Acetic acid-induced abdominal writhing, the tail flick test and carrageenan-induced peritonitis were used to study the analgesic and anti-inflammatory activity of the crude ethanolic extract from Spiranthera odoratissima roots. Pentobarbital-induced sleeping time was used to study the central depressant effect of the extract. The ethanolic extract caused a dose dependent inhibition of acetic acid-induced abdominal writhing and leukocyte migration, and produced a significant, dose-related increase in the duration of sleep. The results suggest that Spiranthera odoratissima roots contain compounds with anti-inflammatory and central depressant actions.
