What is the treatment principle aimed at for LU Yin deficiency?

The treatment principle aimed at for Lung (LU) Yin deficiency is to tonify Yin and nourish fluids. This is because a deficiency in Lung Yin typically manifests as a lack of moisture and nourishment in the lungs, leading to symptoms such as dry cough, hoarseness, and a feeling of dryness in the throat and mouth.

By focusing on tonifying Yin, the treatment seeks to restore the balance of fluids and moisture within the Lung system, thereby alleviating the symptoms associated with the deficiency. Nourishing fluids is essential in this context, as the lungs require adequate moisture to function effectively and maintain their health.

In cases of Lung Yin deficiency, simply clearing heat or tonifying blood does not address the root cause of the problem, which is the depletion of Yin and fluids specific to the lung function. The emphasis on nurturing and restoring Yin is key to the effective management and treatment of this condition.
