Seven Techniques for Combining Herbs
Mutual Accentuation Mutual Enhancement Mutual Counteraction Mutual Suppression Mutual Antagonism Mutual Incompatibility (18 Incompatibles) Single Effect
Mutual Accentuation
Xiang Xu
Combination of two substances with similar functions to accentuate their therapeutic actions
Mutual Necessity
Mutual Enhancement
Xiang Shi
The combination of 2 or more substances with different actions in which one of the substances enhances the effect of the other in a specific clinical situation
Different actions but treat same thing
Mutual Employment
Mutual Counteraction
Xiang Wei
A combination in which the toxicity or side effects of one substance are reduced or eliminated by another substance
Mutual Fear
Mutual Suppression
Xiang Sha

Mutual Killing
Converse of Mutual Counteraction
Emphasis on substance that performs the action
Mutual Antagonism
Xiang Wu
