一、药物差异 1.生药切制:中国的切片比日本大。在切制时为防止粉末和纤维的丢失,多数在生药上喷洒水或酒,使之柔软,然而适得其反,虽说是少量但也是渗出了药液,这是第一个损失。煎煮相同时间,切片越大者则有效成分的提取率就越低,这是第二个损失。很久以前日本就普遍进行细小的切片,那是因为当时的生药昂贵,目的是用少量药而获得 First, the drug differences 1. Raw herbs cut: China’s slices larger than Japan. In order to prevent the loss of powder and fiber during cutting, most of them spray water or wine on the crude drug to make it soft, but counterproductively, although it is a small amount, it also seeps out the liquid, which is the first loss. For boiling the same time, the larger the slice, the lower the extraction rate of the active ingredient, which is the second loss. A long time ago, small slices were commonly made in Japan. It was because the crude drug at that time was expensive. The purpose was to obtain a small amount of medicine.
