1, by time.

That is, the principle of drug use should be considered according to the climatic characteristics of different seasons. As the saying goes, "keep cold with cold, keep cold with cold, keep warm with warm, and keep hot with heat." Food should be the same. "

2, according to local conditions

That is, the principle of drug use should be considered according to the geographical characteristics of different regions. As the saying goes: "Northwest qi dissipates cold; The gas in the southeast is warm. The so-called same disease is treated differently. " That is, the weather in northwest China is cold, and its diseases are mostly external cold and internal heat, so it is necessary to disperse its cold outside and clear its heat inside. The weather in southeast China is warm, and it is easy to produce internal cold due to the leakage of yang, so we should restrain the leakage of yang and warm its internal cold.

3. Adapt people to their needs

That is, according to the different characteristics of patients' age, gender, physique and living habits, the principle of treatment and medication is considered.

Basic principles of drug therapy:

1, the use of each drug should have its indications.

2. Under the premise of ensuring the curative effect, the dosage should be as small as possible and the course of treatment should be short.

Don't use the new medicine easily unless it has obvious advantages over the old one.

5. Formulation of drug administration scheme should be based on the results of scientifically designed clinical trials as far as possible.

6. When determining the administration time, we should consider its influence on the therapeutic effect, adverse reactions and interaction with drugs or food.

7. The administration method should be as simple as possible to improve the compliance of patients.
