The combination of a king’s medicine, a minister’s medicine and an adjuvant’s medicine is one of the methods used in the formation of a Chinese medicine prescription.
The principal drug is the drug that plays a major role in the treatment of the main symptom or disease in a Chinese medicine prescription. The principal drug is the most important drug, reflecting the therapeutic direction of the prescription, and is indispensable in the formula.
The subject drugs are the drugs that assist the principal drugs to strengthen the treatment of the main diseases and symptoms, and mainly play the role of assisting the efficacy of the principal drugs in the treatment.
The adjuvants include adjuvants, adjuvants and anti-adjuvants. The adjuvants are drugs used to eliminate or slow down the toxicity or potency of the principal drug and the subject drug. The adjuvants are drugs used to treat secondary concurrent symptoms. Anti-adjuvant drugs are drugs that are opposite in nature to the principal drug and play a complementary role in the treatment.
