Tremella is used in Chinese medicine to support Lung Yin and to moisten the lungs. It is especially helpful for treating non-productive, dry coughs and Lung Yin deficiency. In addition to its respiratory benefits, tremella has been heavily associated with beauty throughout the Orient, as well as longevity and preserving youth (in TCM, the Lungs govern the health of the skin, so well-functioning Lungs equal beautiful skin).
