65.何谓风化法?试述朴硝、芒硝、元明粉、风化硝的炮制方法? 答:将药物置通风阴凉处,任其失去水分,使其结晶颗粒全部化为粉末的方法叫做风化法。其操作方法: 1.秋冬季节,刮取硷质地面上的白霜放入锅内,加水煮炼,过滤除净泥砂杂质,置容器中静置。待液面析出结晶,细芒如锋状,故称“芒硝”。结于下面的结晶较粗称为“朴硝”。2.取芒硝加二分之一的萝卜入锅内共煮。至萝卜煮烂倾入容器中,置通风阴凉处,使水分蒸发,收集白色粉末,筛去萝卜残渣,即为“元明粉”。加萝卜同煮是除去过多的咸味。3.取芒硝,用能吸水的纸包裹,悬挂于通 65. What is the weathering method? Try to describe the processing methods of Pu’er, Glauber’s salt, Yuan Mingfen, and weathered Nitrate. A: The method of placing the drug in a cool and ventilated place and allowing it to lose water and turning all its crystal particles into powder is called weathering. Its operation method: 1. Autumn and winter season, scrape the white frost on the enamel surface into the pot, add water, smelt and filter, remove the impurities of the net mud sand, and set the container to stand still. The surface of the liquid crystal is precipitated, and the fine awn is like a sharp-edged shape, so it is called “glauber salt”. The thicker crystals below the knot are referred to as “Pitt.” 2. Take Glauber’s salt plus one-half radish and cook it in the pot. Pour radish into the container, place it in a cool and ventilated place, evaporate the water, collect the white powder, and sieve the radish residue. This is the “Yuan Mingfen”. Adding radish to cook is to remove excessive saltiness. 3. Take Glauber’s salt, wrap it with absorbent paper and hang it on
