How is the prescription of traditional Chinese medicine composed?

Traditional Chinese medicine prescriptions often use "monarch, minister and assistant" to explain their composition and function. The monarch drug is the main drug of one side, that is, the drug that plays a major role in the main syndrome. Minister medicine refers to the medicine that can assist and strengthen the attack effect of the main medicine. Auxiliary medicine has two meanings: first, it can supervise the main medicine; First, it can help the main medicine to relieve some secondary symptoms. The former is suitable for cases that are toxic or drug-biased, while the latter is suitable for cases with more syndromes. Making medicine has two meanings: first, it is a meridian-guiding medicine (guiding the main medicine to the diseased meridians, such as Notopterygium root as the sun meridian medicine and Pueraria root as the Yangming meridian medicine); First, it refers to the auxiliary drugs in the prescription, which have the function of harmonizing various drugs.

In fact, the monarch medicine is the main medicine, and the minister, assistant and envoy medicines are all auxiliary medicines. Whether the main and auxiliary drugs are properly matched has a great relationship with the curative effect. The same medicine, due to different compatibility, plays a very different role, or even the opposite.
