许多中药具有双向调节作用。大致可分为二个类型:一是趋中型双向作用,即类似“适应原样作用。”二是偏离型双向作用,即通过正反两个方面使机体功能暂时偏正常状态,有利祛除病邪。造成中药双向作用有两类因素,即机体因素及药物因素,但机体因素与药物因素又是密切联系,二者的划分是相对的。 Many traditional Chinese medicines have bidirectional regulation. Can be roughly divided into two types: First, the trend of medium-sized two-way, that is similar to “adaptation to the role.” Second, the deviation of the two-way effect, that is, through the positive and negative aspects of the body function temporarily biased normal state, to eliminate evils. There are two kinds of factors that cause the two-way effect of Chinese medicine, namely, the body factor and the drug factor, but the body factor and the drug factor are closely related. The division of the two is relative.
