“中医不传之秘在于用量“,此话不无道理。盖其一,从单味药言,量变超出一定限度,必然会引起质变,故剂量不同,功效有别。如附子小量可温补脾肾,中量能祛寒止痛、大量则回阳救逆;红花小量可生血,中量能活血,大量则破血;大黄小量可健胃,中量清湿热,大量则泻下;黄芪小量无利尿效应,中量能显著利尿,大量则反使尿量减少;川芎小量能升高血压、大量反使血压下降等等。处方遣药,切莫一概认为量大则功胜,而盲目追求大剂应用,要因病、因人、因药制宜,力求做到既对症,又适中,否则难以达到预期效果。其 “Chinese medicine does not pass the secret lies in the amount of”, this is not without reason.

Relieving drugs by prescription does not mean that large quantities will be successful, and blindly pursuing large-dose applications must be symptomatic and moderate due to illness, illness, and due to medication. Otherwise, it is difficult to achieve the desired results. its
