The advantage of pure powder tablet of Cordyceps sinensis is that it is more conducive to absorption. The traditional eating methods of Cordyceps sinensis, such as making soup, frying in water, making tea and soaking in wine, are not satisfactory. Heating and stewing will cause the loss and destruction of many core essence components in Cordyceps sinensis, and it is extremely inconvenient to eat. The enzyme contained in Cordyceps sinensis, which is closely related to anti-tumor effect, will be completely inactivated after heating at 80℃ 15 minutes. Eating raw at room temperature is the most valuable way to eat Cordyceps sinensis. The pure powder tablets of Cordyceps sinensis are priced by grams, and the hundreds of boxes of Cordyceps sinensis capsules produced by those health care products companies have no medicinal value. As far as the brand is concerned, there are only two pure powder tablets of Cordyceps sinensis with the purity of 100% in China, one is Beijing Tongrentang and the other is Fulinmen. But it is also a Cordyceps buccal tablet, with a purity of 100%, and the price of Tongrentang is more than twice that of Fulinmen.
