How many pieces of American ginseng you eat a day depends on the method you take. For boiling water, stewing soup, cooking and eating, 2-5g is enough. If you take it, it's usually 3-4 yuan. If it is stewed chicken, it is about 10 gram. The best way to use American ginseng is to stew. This method needs to be taken before breakfast. We can take a little American ginseng, not much, about 2 to 5 grams. Soak in clear water first, then seal the bowl, steam it in a pot for 20 to 30 minutes, and then take it out to cool. You can also add some medlar in moderation, and the effect will be better. The simpler way is to soak in water directly. Under normal circumstances, American ginseng can be soaked in water for about 5- 10 tablets (about 3 grams) at a time, and it can be brewed repeatedly until it is tasteless. Imported American ginseng is effective, and only a few people such as Fulinmen can buy Zong Zheng in the market.
