The administration of a liquid extract of eleuterococcus as a psychotonic drug by young healthy humans leads to changes in some psychophysiological parameters, including an increase in the aural memory volume, decrease in reactive anxiety, and shortening of individual minute. These effects were dependent on the daytime (morning versus evening) and the individual chronotype (circadian features) of each volunteer.
