If a patient with chronic obstructive pulmonary disease is suffering from qi deficiency, taking American ginseng can play a certain therapeutic role, but if it is other types of evidence, the usefulness is not obvious. In Chinese medicine, chronic obstructive pulmonary disease is generally categorized as lung distension, and it is believed that the occurrence of this disease is mainly related to phlegm-heat in the lungs, phlegm clouding the divine orifices, yang-deficiency and water-flooding (yang-qi deficiency causing obstacles to the functioning of water and fluid in the body), and lung-kidney qi deficiency, and so on, and so the treatment is mostly based on the above aspects. Radix Panax Ginseng belongs to the category of qi tonic herbs in traditional Chinese medicine, which has the effect of tonifying qi and nourishing yin, clearing heat and generating fluids, and is suitable for symptoms such as dry mouth and throat, deficiency of qi and yin, fatigue, coughing with phlegm and blood, and irritability due to deficiency of qi and yin. If patients with chronic obstructive pulmonary disease have symptoms of lung and kidney qi deficiency or symptoms related to qi and yin deficiency such as shallow and short breathing, low and timid coughing, chest fullness (chest distension and discomfort), shortness of breath, opening the mouth and lifting the shoulders, inability to lie down, coughing, phlegm and white phlegm, the drug can be used for treatment, which can play a role in replenishing qi. However, if there is Yang deficiency with water flooding, etc., it is not recommended to use this medicine for treatment. In addition, the adverse effects of taking American ginseng are not clear, and quinoa cannot be used at the same time, and a doctor should be consulted for specific medication.
