pharmacological properties.It has been experimentally shown on animals that schisandrin and the entire amount of active principles of Schizandra are low toxic, have a stimulating effect on the central nervous system, enhance positive conditioned reflexes, stimulate respiration and the activity of the cardiovascular system, and increase blood pressure in hypotension. So, tincture and infusion when administered intravenously to laboratory animals at a dose of 0.2-0.5 mg/kg (in terms of dry raw materials) tone up the cardiovascular system, which is manifested by a moderate increase in blood pressure and an increase in the amplitude of heart contractions. At concentrations of 1:1000 – 1:2000, the vessels of the auricle of the rabbit expand. At a dose of 0.2-0.3 mg/kg, the reflex excitability of intact white mice and animals under the influence of narcotic drugs clearly increases. Besides,
Application. Lemongrass is prescribed for toning the functions of the central nervous system, the activity of the heart and respiration, with a general decline in strength due to infectious diseases and intoxication, to increase the working capacity and as a metabolic stimulant. Schisandra tincture is more often used, less often – fruit powder or tablets. They are prescribed to animals inside 2-3 times every day for several days in a row.
