| 【Indication】 |

| 【Pathogenesis】 |
“When the upper body suffers a warm pathogen, the lung is attacked first《Systematic Differentiation of Warm Diseases》- Chapter on Exteriorly Contracted Warm-heat”. The warm pathogen enters the mouth and nasal cavities to attack the lung in the upper jiao. Since the lung is connected with the wei qi, which becomes constrained by the warm pathogen, the distribution and retrieval of wei qi is out of control. As a result, there will be a fever, slight aversion to wind-cold, and an absence or inhibition of sweating. Since the lung fails to diffuse qi, a cough develops. Blockage of the lung system by the warm pathogen causes the throat to be sore. They also damage yin fluids, so the patient feels thirsty. The red tongue tip, thin, white or slight yellow coating, and rapid, superficial pulse are all evidence of an early stage of warm disease. The disease mechanism of a Yin Qiao San pattern is the constraint of the wei qi by the warm pathogen in the initial stage, inhibiting lung distribution. It is characterized by exterior constraint and relatively serious pathogenic heat. The proper treatment method is to vent the exterior with acrid-cool, clear heat, and resolve toxins. |
| 【Application】 |
1. Essential pattern differentiation
The source book describes Yin Qiao San as a gentle acrid-cool formula. It is commonly indicted for an early stage wind-warmth pattern with exterior wind-heat. This clinical pattern is marked by fever, aversion to cold, sore throat, thirst, superficial and rapid pulse.
2. Modern applications
This formula may be used in the following biomedically defined disorders when the patient shows early signs of acute pyrogenic diseases in an early stage of warm disease with the wei qi of the lung constrained by pathogens: common cold, flu, acute tonsillitis, upper respiratory tract infection, pneumonic, measles, epidemic meningitis, type-B encephalitis, and mumps. It is also often used for dermatological diseases such as eczema, German measles, hives, sores, abscesses, furuncles, and swellings.
3. Cautions and contraindications
Yin Qiao San is forbidden for patients with externally contracted wind-cold or damp-heat disease. Since there are many aromatic medicinals in the formula with a light diffusing nature. It is inappropriate to boil it for an extended period of time. |
