As people pay more and more attention to health, nutrition and health care, American ginseng and Korean ginseng are well-known tonic and anti-fatigue health care herbs. Although American ginseng and Korean ginseng are plants of the same family and genus, with similar traits, tissue structures, and chemical components, and are easily confused, they are different after all. So what are the differences between them? First of all, the Korean ginseng grown in Yanbian and Changbai Mountain in Jilin belong to the same species. They are just grown in two different countries, so they have different names. However, they also have the functions of replenishing vitality, producing body fluids, quenching thirst, and calming the mind and improving intelligence. American ginseng is mainly produced in the United States and Canada and is the main species of medicinal materials imported into my country. It was introduced in my country in the 1970s and achieved success in 1980. Now it has been cultivated in Jilin, Beijing, Shaanxi and other provinces and cities, and its quality is basically the same as that of American ginseng produced in North America. The difference between Korean ginseng and American ginseng also lies in their efficacy, and there are also many differences in their efficacy. Korean ginseng is cold in nature and is a hot traditional Chinese medicine. It is a good product for replenishing qi and blood. It has the functions of nourishing and strengthening the body, replenishing vitality, and concentrating the mind and improving intelligence. American ginseng has a bitter, sweet and cool nature and taste. It returns to the lung and stomach meridians. Its main functions are to nourish the lungs and reduce fire, nourish the stomach and promote fluid production. It is generally used to treat symptoms such as yin deficiency and excessive fire, wheezing and coughing up phlegm with blood, febrile diseases that damage both qi and yin, tiredness and thirst, insufficient body fluids, dry mouth and tongue, intestinal heat and blood in the stool. The difference between the two lies in the key difference: replenishing qi and promoting fluid production is their similarity. The difference is that Korean ginseng replenishes qi and tends to support yang; American ginseng replenishes qi and tends to nourish yin. Korean ginseng is better than American ginseng in replenishing qi, and American ginseng is better than ginseng in clearing away heat and promoting fluid production. There is actually not much difference between Korean ginseng and American ginseng. The main reason is that they target different groups of people in terms of efficacy, so everyone can choose according to their own situation.
