FIELD: medicine. SUBSTANCE: the parental source for human antiherpetic preparation producing is precipitate B formed at alcohol separation of plasma blood from native nonvaccinated donors containing initially high antibody content to the simplex herpes virus. Method involves the treatment of aqueous extract of precipitate B with chloroform and dextran sulfate followed by sequence separation with polyethylene glycol (molecular mass is 4000) taken at concentrations 2-4% and 5-7% by volume. For precipitation fraction IgG polyethylene glycol is added up to saturation 12-14% by volume. The content of IgG in human antiherpetic immunoglobulin preparation obtained from ballast fraction (precipitate B) is 97% EFFECT: decreased cost, usage of waste. 1 tbl
