American ginseng is a very good tonic, has the effect of benefiting qi and nourishing yin, when tonifying qi, because it has the effect of nourishing yin at the same time, and is not prone to symptoms of fire, so it is often used in some qi deficiency diseases. Coronary heart disease is a chronic lung disease, which appears only in the late stage, and there are definitely deficiency symptoms in the late stage, so at this time, we can apply American ginseng, but the effect is limited. Because American ginseng replenishes qi, it has the effect of increasing the contractility of the heart and giving positive support to respiration. It can be used to relieve the condition when the pulmonary heart disease is particularly severe, but not fundamentally. The main cause of pulmonary heart disease is lung disease, and the original accumulation of disease is not necessarily deficiency, such as obstructive lung disease, interstitial lung disease, there will be airflow obstruction in the lung or some inflammation in the lungs, which will lead to excessive accumulation of garbage in the lungs, and the lack of oxygen is very serious, and at this time, it is not possible to use American ginseng to completely correct it, and it is necessary to do targeted treatment for the original lung disease. Therefore, American ginseng can be used for pulmonary heart disease, but the effect is not very big.
