Emphysema belongs to the category of “cough” and other diseases in traditional Chinese medicine, and it can be consumed if there are corresponding indications and no contraindications, so it is inaccurate to say that people with emphysema can not drink American ginseng water. American ginseng is sweet, slightly bitter, cool in nature, belonging to the heart, lung and kidney meridians, has the effect of nourishing yin and clearing heat (nourishing yin fluid, clearing heat), tonifying qi and generating fluids, and can be used for treating diseases such as dry mouth and thirst, deficiency heat, cough, phlegm and blood, etc. It can also be used for treating diseases of deficiency and cold in the middle yang, cold and dampness. It should be used with caution for people with deficiency and coldness in the middle yang, internal obstruction of cold and dampness, and people with dampness, heat and fire; it should not be used with quinoa. If emphysema patients have the above indications without contraindications, they can drink American ginseng water under the guidance of doctors, so the statement that emphysema patients cannot drink American ginseng water is not accurate. Moreover, the active ingredient of single medicine in water is limited and only plays an auxiliary role, which cannot replace the therapeutic effect of multiple medicines used together. If emphysema patients have any discomfort, please consult a regular hospital and be treated by a professional doctor.
