中药汤剂是我国应用最早最广泛的一种剂型，徐良路《医药源流论》中说：“煎药之法直深讲，药之效不效，全在此平。”因此，要使药发挥疗效，必须掌握煎药的方法。一、煎药用具前人认为：“银为上，磁者次之”。不主张用铜锅、铁锅。因大部分中药是植物，其中食有模酸，遇铁加 Chinese medicine decoction is one of the earliest and most widely used dosage forms in China. Xu Lianglu’s “Medicine Origin Theory” states: “The method of decocting is straight to say that the effect of medicine is not effective and it is all in this level.” Therefore, it is necessary to make medicines play a role. The curative effect must master the method of decoction. First, the decocting utensils predecessors thought: “Silver is the first, and magnetic is the second.” Do not use copper pans and iron pans. Because most Chinese herbs are plants, there is acetic acid in the food, and iron is added to it.
