The Chinese medicine yuzhu is used to nourish yin, moisturize the lungs, generate fluids and quench thirst (promoting the production of fluids to relieve thirst). Sweet in taste and slightly cold in nature, it belongs to the lung and stomach meridians. Its effects are to nourish yin, moisten dryness, generate fluids and quench thirst, and it can be used for dry and hot coughs due to lung and stomach yin injuries, deficiency of yin fluids, dry pharynx and thirst, and thirst due to internal heat. Its strong effect of nourishing yin can also be used for symptoms such as hunger without appetite, dry mouth and tongue caused by the late stage of fever when the stomach yin is damaged and not recovered, or internal fire injuring the stomach yin. If the body is weak in yin and wind-heat is resumed, this product can also be used with other traditional Chinese medicines such as Bai Wei, Mentha piperita and Platycodon grandiflorus to treat the disease. It should be noted that because it nourishes yin and moistens dryness, it is prohibited for people with phlegm-dampness and stagnation of qi, and should be taken with caution for people with spleen deficiency and loose stools (thin and unformed feces). The medication should be taken under the guidance of a physician, and should not be used on its own.
