1. phase acupuncture: drugs with similar performance and efficacy can enhance their original curative effect. For example, gypsum combined with Anemarrhena asphodeloides can obviously enhance the curative effect of clearing heat and purging fire; The combination of rhubarb and mirabilite can obviously enhance the curative effect of diarrhea fever.

2. Matching: that is, some drugs have certain characteristics in performance and curative effect. One drug is the main one and the other is the auxiliary one, which can improve the curative effect of the main drug. For example, the compatibility of Astragalus membranaceus and Poria cocos can improve the therapeutic effect of Astragalus membranaceus. Scutellaria baicalensis Georgi for clearing heat and purging fire is compatible with rhubarb for clearing heat and purging fire, and rhubarb can improve the curative effect of Scutellaria baicalensis Georgi for clearing heat and purging fire.

3. Mutual fear: that is, the toxic reaction or side effects of one drug can be alleviated or eliminated by another drug. For example, the toxicity of raw Pinellia ternata and raw South Star can be reduced and eliminated by ginger, so raw Pinellia ternata and raw South Star are afraid of ginger.

4. killing each other: that is, one drug can reduce or eliminate the toxicity or side effects of another drug. For example, ginger can reduce or eliminate the toxicity or side effects of raw Pinellia ternata and raw South Star, so ginger kills the toxicity of raw Pinellia ternata and raw South Star. It can be seen that mutual fear and mutual killing are actually two dosage forms with the same compatibility, especially in the mutual treatment between drugs.

5. Dislike: that is, two drugs are used together, and one drug interacts with the other drug, reducing the original curative effect or even losing the curative effect. For example, ginseng hates radish seeds, because radish seeds will weaken the qi-invigorating effect of ginseng.

6. On the contrary: the combination of the two drugs will produce toxic reactions or side effects. Such as "eighteen evils" and "nineteen fears".
