Improvement in Light and Colour Perception in Humans with Prolonged Use of Eleutherococcus

According to commonly held concepts, the specific activity of psychotropic substances of different classes may be associated not only with direct pharmacological interference with the activity of the brain but may also be determined to some extent by changes in vision. Confirmation for this comes from the ability of the psychostimulant caffeine to alter the functional state of the retina of the eye in healthy individuals [2,4]. With this in mind, it is interesting to assess the effect on the visual system of the psychotropic agent eleutherococcus, which, as a plant adaptogen, has moreover positively proved itself in ophthalmological practice [7,12].
