Excessive Yin deficiency and fire (deficiency of Yin and essence in the body, resulting in hyperactive fire) can be regulated by taking Chinese medicines such as Dendrobium and Jade Bamboo. The medication should be taken under the guidance of a doctor. 1. Dendrobium is slightly cold in nature, sweet in taste, and belongs to the stomach and kidney meridians. It has the effects of benefiting the stomach and generating fluids (nourishing the stomach by replenishing the fluids in the stomach), nourishing yin and clearing away heat (nourishing the yin essence and clearing away the heat), and is clinically used for treating the symptoms of dryness in the mouth, heartburn, and thirst caused by yin injuries and fluids deficiencies. Note that it is forbidden to be taken by those who have not injured the yin in the early stage of warm-heat disease, those who have not been dried out in damp-warm disease (warm disease caused by feeling dampness and heat), and those who have deficiency of cold in the spleen and stomach (spleen and stomach weakness and cold). 2. Yuzhu is sweet in taste and flat in nature, belonging to the lung and stomach meridians, with the effects of nourishing yin, moistening dryness, generating fluids and quenching thirst (promoting the production of fluids to relieve thirst), and is often used in the treatment of dry and hot coughs, dry pharynx, and thirst resulting from yin injury of the lungs and stomachs. It should not be taken by people with phlegm-dampness and stagnant qi, and should not be taken by people with spleen deficiency and loose stools (thin and unformed feces). If you are experiencing discomfort, it is recommended to standardize the treatment under the guidance of a professional doctor, and not to use the medicine blindly on your own.
