Cordyceps is an organism of the ergot family. It is a valuable traditional Chinese medicine with medicinal value. Chinese medicine believes that Cordyceps is the only drug with the same complementary effect of yin and yang. Western medicine believes that the most medicinal value of Cordyceps is: anti-gene mutation, that is, anti-cancer.
For the cough effect: Cordyceps ginseng does not have this kind of effect in my understanding. Cordyceps, on the other hand, can indirectly have a cough suppressant effect.
Eating Cordyceps to stop coughing: the best way is: the Cordyceps with 20 degrees below the cool water, rinse for about 100 seconds, wash off pathogenic bacteria, parasitic eggs, sediment and so on. Then put it in your mouth and chew it. Chew as long as possible to achieve the purpose of breaking. The more you chew, the better. Afterward, you can choose to hold it in your mouth so that it is slowly absorbed through the oral mucosa, or you can take it with cool water. Of course, I suggest the former, through the oral mucosa absorption, can have the most direct, the best effect.
