traditional pharmaceutical principles

1. contrary to the system: modification of medicinal properties

refers to auxiliary materials (including drugs) with opposite medicinal properties to restrict the bias of traditional Chinese medicine or change its medicinal properties. For example, if the bitter and cold rhubarb is processed with wine extracted from pungent heat, the medicinal properties will be reduced to ascending. Coptis chinensis processed with pungent Evodia rutaecarpa can kill its chilling nature. Processing Fructus Alpinae Oxyphyllae with salty, cold and moist salt water can alleviate its warm and dry nature.

2. Preparation based on mutual resources: enhancing drug efficacy

refers to auxiliary materials with similar medicinal properties or some processing method to enhance drug efficacy. Capital means funding. If bitter Rhizoma Anemarrhenae and Cortex Phellodendri are processed with salty and cold salt water, the effect of nourishing yin and reducing fire can be enhanced. Cured Rhizoma Curculiginis and Actinolite with wine can enhance the effect of warming kidney and supporting yang. Honey-baked licorice can enhance the effect of tonifying middle energizer and benefiting qi.

3. fear each other (or kill each other) for the system: reducing toxicity

refers to the use of some auxiliary materials to restrict the toxicity and side effects of a drug to process it. For example, ginger can kill Pinellia ternata and Arisaema (that is, Pinellia ternata and Arisaema fear ginger), so ginger is used to process Pinellia ternata and Arisaema.

4. Opposing evil is the control: restraining strong

is the extended application of the content of "opposing evil" in the compatibility of traditional Chinese medicine in processing. "Mutual aversion" refers to the combination of two drugs, one of which can reduce or lose the effect of the other. Generally, it belongs to compatibility taboo. However, according to this principle, some auxiliary materials or some methods can be used to weaken the potency of the drug during processing, such as parching Fructus Aurantii Immaturus with bran to alleviate its gas-breaking effect. For drugs that have adverse reactions after taking, the meaning of "opposing evil as the control" is similar to that of "opposing fear as the control".
