Qi-Yin Enrichment was first published in 1231 AD and was edited by Li Dongyuan in “Differentiation on Internal and External Diseases”. It is an excellent ancient recipe for replenishing Qi and Yin of Heart and Lung. It is widely used in cardiopulmonary Qi and Yin weakness diseases, such as tuberculosis, chronic lung disease rehabilitation, etc. This formulation replenishes Qi and replenishes Yin by nourishing and not drying with a peaceful nature. It is a commonly used healthcare product to restore physical strength. For example, in the summer heat when running a marathon and doing other demanding sports with excessive sweating, loss of Qi and Yin, upset, weakness of limbs and other symptoms, this formulation can be used to invigorate Qi and nourish Yin and restore physical strength.

It is said that Qianlong, the emperor of the Qing Dynasty in China, also took Sheng Mai San daily to extend his health. Large-dose use is also the first aid for Qi and Yin collapse. Wang An’s “Medical Recipe Collection” from Qing Dynasty in 1682 said: “People have a pulse showing death, the so-called “dead blood pulse” can be revived by taking Sheng Mai San. It has a great effect.”

Modern pharmacological studies have also confirmed that Qi-Yin Enrichment can strengthen the heart contractility. It improves the blood supply of myocardium, protects ischemic and hypoxic myocardial cells and plays a role of anti-acute myocardial infarction. It can also excite the central nervous system and adjust the heart rate. Therefore, this formulation can be used to treat arrhythmia, chronic heart failure and diabetes.
