《伤寒论》作为一部理论与实践紧密结合的中医典籍,在临床思维上也给后世以多种启迪。论中对于方剂的加减运用即是其中一个重要的方面。昔人有云:“盖用方之妙,莫如于加减;用方之难,亦奠如于加减。苟不精仲景之旨,药性不谙,配合不讲,见头治头,滥为增损,不徒失古方之趣,亦使互相牵制,坐衍时机者,往往有之,加减岂易言乎!”(《药治通义· “Treatise on Febrile Diseases” is a book of traditional Chinese medicine closely integrated with theory and practice. It also gives many enlightenments to later generations in clinical thinking. The addition and subtraction of prescriptions in Chinese medicine is one of the important aspects.

It is not the purpose of Jing Zhongjing, its medicinal properties do not work, and it does not speak well. In order to increase damage, it does not lose the interest of the ancient world, but also causes mutual containment. Those who take advantage of the opportunity often have exceptions and errors.”
