Lung-Qi deficiency

Hu Tao Ren is sweet and warm, and enters the Kidney and Lung meridians. E Jiao is sweet and neutral, and enters the Liver and Kidney meridians. Both are moist in nature and are able to moisten the Lung and tonify the Kidney-essence and blood. They are mainly selected in formulas to treat chronic conditions of Lung-Qi deficiency where Kidney deficiency is obviously involved. The difference between these two substances is that Hu Tao Ren is more suitable for treating Kidney-Yin and Kidney-essence deficiency E Jiao is better suited for use in cases of blood deficiency. 

Bu Fei Tang is a formula that directly tonifies the Lung-Qi and treats the typical condition of Lung-Qi deficiency. The manifestations are shortness of breath, cough, spontaneous sweating, a pale complexion, a pale tongue and a weak pulse. 

Shu Di Huang, as deputy, treats the coexisting syndromes. This herb is sweet and warm, and enters the Kidney meridian. It can tonify the blood and Kidney-essence, which are weakened in chronic conditions or in constitutional conditions of Lung-Qi deficiency. 

Sadness or depression due to Lung-Qi deficiency add He Huan Pi (Albiziae cortex) and Bai He [Lilii bulbus) to moisten the Lung and spread the Qi. 

In this section, the strategies of composing the formulas that tonify the Heart-blood and Liver-blood are discussed because they are common syndromes. The related Spleen disorder is discussed in Section 1, Syndrome of Spleen-Qi deficiency, the related Lung disorders are discussed in Section 2, Syndrome of Lung-Qi deficiency and Section 6, Syndrome of Lung-Yin deficiency, and the related Kidney disorder is introduced in Sections 10 and 11, Syndrome of Kidney-Yin deficiency and Syndrome of Kidney-Yang deficiency, respectively.
