A traditional formula for fatigue, shortness of breath, and Heart and Lung support

Qi-Yin Enrichment (Sheng Mai San) supports the body when fatigue, shortness of breath, dryness, and reduced stamina show that both energy and fluids are running low. Li Gao first recorded it in Nei Wai Shang Bian Huo Lun (Clarifying Doubts about Injury from Internal and External Causes) in 1247. Practitioners have long chosen it when the lungs and heart no longer feel strong enough to support breathing, circulation, and endurance properly. It remains a trusted choice when the body feels tired, dry, and less resilient after long periods of depletion.

When to use it

In Traditional Chinese Medicine, practitioners choose Qi-Yin Enrichment when both Qi and fluids have become depleted. Shortness of breath may appear. The mouth may feel dry. Thirst may increase. Some also notice chronic dry cough, palpitations, sweating, low stamina, or tiredness that does not improve easily.

Many choose this formula for fatigue after illness, chronic dry cough, low endurance, palpitations, shortness of breath, dehydration after heat or sweating, and long-term weakness affecting the heart and lungs. It suits those who want support when the body feels run down, dry, and easily exhausted. This formula replenishes Qi and nourishes Yin without being harsh or drying. Many use it to help restore physical strength. It may also suit times of heavy sweating and physical strain, such as summer heat or demanding sport, when weakness and fluid loss develop together.

Why it stands out

What makes Qi-Yin Enrichment so useful is its focused restoring action. It does not only boost energy. It also helps rebuild fluids, support breathing, and steady the body when weakness and dryness appear together. This makes it a strong choice for natural support when endurance, recovery, and resilience need rebuilding from a deeper level.

Research

Research on Qi-Yin Enrichment has shown encouraging results in angina, arrhythmia, coronary heart disease, chronic heart failure, and cardioprotection. Studies have reported improved cardiac function, better circulation, enhanced exercise tolerance, and antioxidant support. Research also suggests better blood supply to the myocardium, stronger cardiac contractility, and protection of heart tissue during ischemic or hypoxic stress. Some findings also point to effects on heart rate regulation and recovery after fluid depletion or shock. This gives Qi-Yin Enrichment strong modern relevance and supports its traditional use when the heart, lungs, and overall vitality need extra support.
