This drug can be used in the treatment of spleen and stomach qi deficiency, body fatigue, stomach yin deficiency, dry mouth and low food intake, lung deficiency and cough. It should be noted that it is not suitable for patients with spleen deficiency with dampness, cough with excessive phlegm, and spleen deficiency with loose stools. 2. Jade Bamboo is sweet and slightly cold in nature, belonging to the lung meridian and stomach meridian, with the effect of nourishing yin, moisturizing the lung, generating fluids and quenching thirst. It can be used in the treatment of lung and stomach yin injury, dry and hot cough, dry throat and thirst.
