Professor Wanyousheng from Jiangxi once said: "Many people believe that influenza is a sexually transmitted disease, so they use cooling medicines for treatment. Initially, the main approach was to use pungent-cooling medicines, with Honeysuckle and Chrysanthemum Flower widely used. Later, it gradually shifted to bitter and salty Great Cold medicines (such as Isatis Root, etc.). The rationale was that they could inhibit virus growth. To this day, the domestic common cold medicine market is dominated by cold and cooling medicines. As a result, a large number of wind-cold common cold patients, who could have been cured with one or two doses of Ephedra Decoction that releases the exterior with pungent-warmth, are instead casually treated with cold and cooling medicines. This causes the exterior cold to become trapped and unresolved, leading to chronic cough, persistent low fever, or throat discomfort, among other consequences. Such cases are frequently seen in clinical practice, yet neither doctors nor patients seem to reflect on this."
