If pathogens are allowed to penetrate deeper into the interior of the body, the situation can become more critical. This is the stage when people are hospitalized with severe difficulty breathing. A simple formula that was used in Wu Han, China addresses this stage: Gua Lou Xie Bai Ban Xia Tang. One aspect of this stage is chest pain and potentially increased cardiovascular involvement. For this reason, some Chinese doctors included the ingredient Dan Shen, Red Sage root. This herb increases the function of the lungs to exchange oxygen and protects the heart. The formula as a whole ventilates the lungs, transforms phlegm, and treats Chest Bi (pain). It helps the patient breathe in a crucial stage of the illness.

Contains extracted and decocted Quan Gua Lou, Xie Bai, Ban Xia Jiang, Dan Shen, grain alcohol (~18% by volume), distilled water and vegetable glycerin.
