上海地区老药工过去有这样一句俗语;“丹皮封刀。”就是讲到阴历12月,安徽新货凤丹皮登场,运到上海后已是阴历大寒季节了,各大药店为了使新货丹皮经过切制加工,能符合色泽白、粉性足、香气浓好的质量要求,就赶在阴历十二月二十日左右前加工切制完毕。切完丹皮后,就年关内不切药了,这就是所谓的“丹皮封刀”。这是很有道理的。在阴历12月,气温低,通常在10℃之内,气候比较干燥,正是加工丹皮好季节。切制加工后的饮片(成品)色泽白,香气浓,就是因为此时气温低,可使切制加工产品香气足,因此,丹皮中丹皮酚损失少。从老药工加工切制丹皮经验,对照目前切制厂
In the past, old pharmacies in Shanghai had such a saying; “Danpi knife.” It is said that in December of the lunar calendar, Anhui new goods, Fengdanpi, appeared on the market. After being shipped to Shanghai, it was the lunar calendar and the cold season. The major pharmacies in order to make new After the cut and processed products, the Danshui meets the quality requirements of color, whiteness, powder and aroma, and they are processed and finished before December 20th of the lunar calendar. After cutting the Dan Pi, there is no medicine cut in the year. This is the so-called “Danpi knife”. This is very reasonable. In December of the lunar calendar, the temperature is low, usually within 10°C, and the climate is relatively dry. It is a good season for processing the Dan Pi. Cut processed processed pieces (finished products) are white in color and rich in aroma. This is because the low temperature at this time can make the cut processed products full of aroma. Therefore, paeonol has less loss in paeonol. From the old pharmacists to process and cut Danpi experience, compare the current cutting factory
