黄芩的炮炙方法有冶浸、燙、煮等,各地标准不一,而处理时间差別很大,如浸泡时间从2～48小时,烫的时间从2～24小时,煮的时间从10分钟到4小时不等。对于这些不同的炮炙方法,各有各的沦点。根据传统经验南方有人认为黄芩有小毒,必须用冷水浸泡至色变绿去毒后再切制饮片,叫淡黄芩者为佳;而北方又认为黄芩遇冷水则变 The methods used by Huanghua include leaching, scalding and boiling. The standards vary from place to place. The processing time varies greatly. For example, the soaking time is from 2 to 48 hours, the hot time is from 2 to 24 hours, and the cooking time is from 10 minutes. Up to 4 hours. For these different artillery methods, each has its own flaws. According to traditional experience, some people in the south think that there are small poisons in the yellow peony root, so they must be soaked in cold water until the color changes to green and then cut the pieces of the decoction. The pale yellow peony is better; and the north also thinks that the yellow peony changes in cold water.
