Appropriate treatment means formulating suitable therapeutic methods according to the season, region, and the individual's constitution and age.

1. Treatment in accordance with seasons: The changes in climate throughout the four seasons have a certain impact on the human body, and treatment should also consider the characteristics of the weather. For example, during the hot summer, when the striae and interstice are open, excessive use of pungent and warm herbs for those suffering from wind-cold common cold should be avoided to prevent excessive sweating and the dissipation of yang qi, which could injure body fluids. In the cold winter, when the striae and interstice are dense, the use of pungent and warm herbs for wind-cold common cold can be slightly heavier to allow the wind-cold to be resolved through sweating, but the patient's constitution must also be considered.
2. Treatment in accordance with local conditions: China has a vast territory with varying climates in different regions. In the hot and rainy southern regions, patients often exhibit pattern of dampness and heat, and treatment must address dampness-heat. In the dry northern regions, dryness pattern may occur, and it is necessary to differentiate between cool dryness and warm dryness for treatment. Additionally, certain regions have endemic diseases that require special attention.
3. Treatment in accordance with individuality: Each person's specific circumstances differ, and treatment should be flexibly tailored to these specifics. For example, in terms of gender, men and women have different physiologies and specific ailments, so treatment must consider their physiological and pathological characteristics. In terms of age, children have delicate organs, while the elderly have declining qi and blood, each with their own common diseases. In terms of constitution, each person's innate endowment and postnatal care often differ, leading to varying physical constitutions—not only in strength but also in tendencies toward cold or heat, or the presence of chronic diseases. In terms of occupation, working conditions can be related to the occurrence of certain diseases, so the patient's occupation must be considered during diagnosis and treatment.
