Cordyceps sinensis can be divided into true and false, low altitude and high altitude, first and last grass, new grass and old grass. The identification of authenticity can be divided by appearance, and quality needs to be identified by experience. If you buy it in different places, the price gap is also very large. Based on years of experience in purchasing Cordyceps sinensis, I suggest that it is best to choose some big brands. Here, I want to give a big praise to Dongyangguang Cordyceps sinensis. It has been affirmed by Wei, Zhang Boli, Zhong Nanshan and other academicians of Chinese Academy of Sciences, and obtained a number of patents on Cordyceps sinensis. Then FD aerospace freeze-drying preservation technology and intelligent ecological preservation technology are used to keep the fresh quality and nutrition of Cordyceps sinensis. It doesn't matter if the novice Xiao Bai can't identify it. You can buy it directly.
