Anxiolytic effect of homeopathic preparation of Pulsatilla nigricans in Swiss albino mice.

Background: The homeopathic preparation of Pulsatilla nigricans is used in the treatment of anxiety related disorders. Though in clinical use for many years, the anxiolytic activity of Pulsatilla nigricans (Puls) has not been evaluated experimentally. Hence the present study was conducted in Swiss albino mice to evaluate the anxiolytic activity of Puls and compare its activity with the standard anxiolytic drug, diazepam.
