Pathogenesis Analysis of Shen Su Yin


Shen Su Yin targets qi deficiency with external wind-cold and internal phlegm-dampness. When the spleen and lungs lack qi, phlegm-dampness builds up internally. If wind-cold then invades, it triggers symptoms.


Wind-cold on the body’s surface causes chills, fever, no sweating, headache, and nasal congestion (surface symptoms), while internal phlegm-dampness leads to white phlegm, cough, and chest fullness.


Indications:

  • Chills and fever.

  • No sweating.

  • Headache.

  • Nasal congestion.

  • Cough with white phlegm.

  • Chest and upper abdominal fullness.

  • Fatigue and weakness.

  • Shortness of breath and reluctance to speak.

  • White tongue coating.

  • Weak pulse.
