The present study is aimed to evaluate the anxiolytic activity of ethanol and aqueous extract of cinnamomum cassia bark using elevated plus maze test (epm) model in rats. ethanol and aqueous extract of cinnamomum cassia bark had increased number of entries and time spent in open arms while they decreased the number of entries and duration of time spent in closed arm of the EPM. In a similar fashion, the diazepam increased the percentage of time spent and percentage of arm entries in the open arms (*P <0.05, **P <0.01). the bark had anxiolytic activity (*P <0.05, **P <0.01) in EPM.
