METHOD FOR PREPARING AGENT FOR SKIN TREATMENT Russian patent published in 2003 - IPC

FIELD: medicine, dermatology, pharmaceutical technology. SUBSTANCE: invention relates to methods for preparing medicinal preparations. Medicinal raw (hazel stems collected in period of intensive sap flow) preliminary dries at temperature 16-45 C up to moisture index 12-23% is milled to particles size 5-24 mm and placed into chemically and thermally stable glassware connected with capacity by pipe. Glassware is fitted into heating device able to create temperature 300-600 C and capacity placed into cooling device. As result, condensate is accumulated into capacity and its bottom fraction obtained after settling for 20-24 h is used as the end product. Invention provides reducing energy consumptions required for raw sublimation and to enhance the yield of the end product. EFFECT: improved preparing method.
