Authors propose use of fluid extract in hydroalcoholic menstrum to 50 %, obtained by percolation, and as a alternative variant to bimaceration. Maceration is discarded as technological process. Annexes and tables are presented. Which include quality parameters results, determined to dried up drug, and to furnace with air recirculation, to no more than 40 ?C in both tecnological variants (organoleptic, refraction rate (R.R.), pH relative density (R.D.), total solids (T.S.), alcoholic content (A.C.), capilar analysus, and qualitative chemical composition.
