By the way, it is not necessary for healthy young people to supplement Cordyceps sinensis. In other words, to put it bluntly: Cordyceps sinensis is not an elixir. Normal healthy people eat the most to stay healthy, and there is no feeling and no need. My family started to buy it in Tongrentang, and now it's in Chengdu, a shopping mall in Tibet. The old man at home didn't get so sick after eating it, but I ate it myself, and it felt like "nothing."
