What is the treatment principle for Exterior syndromes?

In Traditional Chinese Medicine (TCM), the treatment principle for Exterior syndromes focuses on addressing pathogens that invade from outside the body, such as wind, cold, heat, or dampness. These exogenous pathogens can cause symptoms like chills, fever, body aches, and a stiff neck, indicative of an Exterior syndrome.

The goal of treatment in these situations is to expel the exogenous pathogens. This is achieved by using methods such as acupuncture, herbal formulas, and other techniques that promote sweating or otherwise help the body to eliminate the invading factors. By driving out these pathogens, the balance of Yin and Yang in the body can be restored, and the patient can recover more quickly.

The other options represent different treatment principles that may apply to other types of syndromes. Reinforcing the body's Yang energy can be applicable in cases where there is Yang deficiency, while tonifying the organs relates more to treating deficiencies or supporting weaker systems. Cooling down internal heat is relevant in situations where there is excessive heat but is not specifically aligned with the approach for treating Exterior syndromes. Thus, the focus on expelling exogenous pathogens is the most fitting treatment principle for this scenario.
