Shen Su Yin modified(LPI) is formulated for individuals with lingering respiratory weakness, chronic dampness, and low immune resilience following viral or environmental illness. It is especially suited for those who experience chronic cough with phlegm, nasal congestion, headache, shortness of breath, fatigue, poor appetite, and a sensation of heaviness in the limbs or chest(including chest tightness). Patients may also report sensitivity to cold and damp weather, brain fog, and frequent upper respiratory infections. This formula supports Lung and Spleen Qi, transforms phlegm, and gently releases the exterior when necessary, while strengthening the body's core ability to recover. Ideal for post-infectious syndromes, damp-predominant Long Covid, or individuals stuck in the aftermath of unresolved respiratory illness, Shen Su Yin modified(LPI) restores clarity, breath, and immune stability from the inside out.
