Hi, Asako Ganshi Tang is from "The Treatise on Typhoid Fever", which consists of ephedra, almonds, roasted licorice, and gypsum, and it is a good formula for clearing heat from the lungs. It is a good formula for clearing lung heat. The main medicines are gypsum and ephedra, and the amount of gypsum is three times as much as that of ephedra. Explanation: Evil heat congests the lungs, and the lungs lose their ability to propagate and descend due to heat compression and qi reversal. The ancient formula uses ephedra to promote the lungs to calm asthma and dissipate the heat. However, ephedra is warm in nature, so it is matched with cold gypsum, the dosage of which is several times more than that of ephedra, to control its nature and to clear and disperse the heat in the lungs. The combination of the two drugs is to promote the lung without helping the heat, and to clear the lung without retaining the evil. Almonds lower the lung qi and cough, and ephedra with a matching, a propaganda and a lowering, but also can calm the asthma. The hot licorice eases the lung qi, helps ephedra and almonds to stop coughing and asthma, and also harmonizes the medicinal properties of the drug. The four medicines are strictly paired, the dosage is careful, and widely spread. The above is my understanding of the hemp apricot glycyrrhiza soup, I hope my answer will be helpful to you, thank you
