Tremella Fuciformis is a species of fungus that produces a white, frond-like, gelatinous fruiting body. It is widespread, especially in the tropics, where it can be found on the dead branches of broadleaf trees. It is commonly known as snow fungus, snow ear, silver ear fungus, and white jelly mushroom.
It is rich with dietary fibers and Vitamin D and is used in Asia as a Qi and immune tonic as well as being highly prized as a youthful complexion tonic. Tremella is a very popular medicinal mushroom used in cough syrup for treating chronic tracheitis and a number of other cough-related conditions such as asthma, dry cough and heat in the lungs in traditional Chinese medicine.
Imperial Concubine Yang (719-756), considered to be the most beautiful woman in Chinese history, used tremella mushroom for her facial and body maintenance.
