It is stated in the discussion: The *Neijing* (Classic of Internal Medicine) records, "The Zang-True Qi resides highest in the Lung," and further states, "When True Qi is depleted, deficiency ensues." Currently, cold in the Lung causes insufficiency of the Lung's True Qi, leading to weakness in the Upper Jiao (Upper Burner). Due to this deficiency, there is an inability to control the Lower Jiao (Lower Burner), resulting in Lung萎 (Lung Flaccidity Syndrome) above and frequent urination below. This may even manifest as spitting of saliva and froth accompanied by a desire to cough but an inability to do so; all these are symptomatic manifestations of this condition. The treatment principle should be to harmonize using warm herbs.

For treating Lung Flaccidity Syndrome with spitting of saliva and froth, desire to cough but inability to do so, and frequent urination, use Gan Cao Gan Jiang Tang (Licorice and Dried Ginger Decoction): Zhi Gan Cao (Honey-fried Licorice Root, *Glycyrrhizae Radix et Rhizoma Praeparata cum Melle*) [4 liang], Pao Gan Jiang (Processed Dried Ginger, *Zingiberis Rhizoma干燥*) [2 liang].
