The difference between the efficacy of white ginseng and American ginseng
When it comes to ginseng, people often think of ginseng. In fact, in addition to ginseng, there are different ginsengs such as American ginseng, Codonopsis pilosula and Panax ginseng, which all have the function of tonifying qi, but there is a difference in their use.
Ginseng is warm in nature, which can replenish the qi of the spleen and lungs, and can also replenish the vital energy, which is a good medicine for those who have recovered from serious illnesses and have been sick for a long time and are weak and biased towards qi deficiency. This kind of people often manifested as fear of cold, panic and shortness of breath after activity, dizziness, sweating, loose stools, low blood pressure, weak pulse, and so on. As a warm tonic, ginseng should be used with strict indications. People with high blood pressure, history of cerebral hemorrhage, dry mouth, easy to catch fire, reddish color, dry stools, etc. should not take it. Some people's physique is weak, but partial to Yin deficiency, such as accompanied by heat in the hands and feet, dry eyes, tinnitus, lumbago, urination, etc., can not use ginseng, so as not to add oil to the fire.
Cynanchum is cold in nature, in addition to replenishing gas and generating fluids, it can also clear the fire, nourish the stomach and benefit the lungs, and will not lead to "fire", elevated blood pressure and other problems. However, it is still a medicine and not suitable for everyone. American ginseng is suitable for those who have the above symptoms of qi deficiency, but also with fluid damage or internal heat of yin deficiency, such as red face, dry mouth, heartburn and insomnia.
