FIELD: medicine. SUBSTANCE: invention relates to preparing drugs from animal raw waste. Method involves spleen grinding, extraction with an aqueous extractant in combination with additional effect of low-frequency ultrasonic oscillation followed by separation of extract by centrifugation, dialysis and lyophilization. The weight ratio of spleen and water can be 1/6-1/3, mass is 25000-50000. Ultrasonic frequency is taken from the range 20-70 kHz at intensity 0.1-2.3 W/cm2. EFFECT: increased yield of the end product, decreased time of its preparing. 5 cl, 5 tbl
