Abstract

The purporse of the present study was to see the Panax Ginseng has any influence upon the learning and emotion in animals. In order to asses this purpose, mice were tested in a single-T water maze and in an open-field. The results obtained were as follows. (1) As compared to placebo control, acquisition of the maze learning was tended to improve after the treatment of the Ginseng glycoside with doses of 2.5 and 5.0 ng/kg. (2) Ginseng animals with dose of 20mg/kg exhibited a significant sedative effect on the ambulatory behaviour in the open-field.
