《黄帝内经·灵枢·痈疽》
用泻法去治疗实证，就能使邪气衰减，但泻得太过，反会损伤正气，泻法宜急速出针，可迫使邪气衰减，若仅用留针法，不能及时泻邪，则病情先后如一，仍不见好转。
泻则不足，疾则气减，留则先后。从实去虚，补则有余。
Using catharsis to treat real symptoms can reduce evil qi, but catharsis is too much, which will damage the righteousness. The catharsis method should be used to puncture the needle quickly, which can force the evil qi to decline. If only the needle retention method is used, the evil qi cannot be released in time, and the condition will remain the same and will not improve.
