It is sweet in taste and slightly cold in nature. It is good at generating fluids to quench thirst, nourishing yin and moisturizing dryness. Clinically, it is often paired with mulberry leaf, maitake, and sasanqua for the treatment of dryness and heat in the lungs and stomach, deficiency of yin fluid, dry cough with little phlegm, and dry mouth and throat. For those who suffer from cool dryness and lung injury, it can be paired with perilla leaves, beard, almonds and so on. In addition, combining yuzhu with smallpox pollen, Chinese yam, raw dihuang, and raw kudzu root can enhance the efficacy of generating fluids to quench thirst, nourish yin and clear heat (nourish yin essence and remove heat), and treat internal heat and thirst (internal heat accompanied by symptoms such as overeating, excessive drinking, excessive urination, etc.). If the stomach yin is not restored in the late stage of heat illness, and the internal fire injures the stomach yin, resulting in loss of appetite and dryness of the mouth and tongue, jade bamboo can be combined with Radix et Rhizoma Polygoni Multiflori and Radix et Rhizoma Polygoni Multiflori.

The use of Yuzu should be under the supervision of a doctor.
