☯ TCM Properties
Nourishes Yin and cleanses the Lungs
Traditional Chinese Uses
Feng Huang Yi is the thin inner membrane of the hen's eggshell (Gallus gallus domesticus; Membrana Follicularis Ovi), a sweet substance entering the Lung channel. It nourishes Yin and clears the Lungs, moistening dryness of the respiratory tract, and is used chiefly for chronic and lingering dry cough and for Lung Yin deficiency with a dry, scratchy throat. A characteristic traditional application is hoarseness and loss of voice (aphonia), where it soothes and moistens the throat.
It is also applied to scrofula and, topically, to non-healing sores and ulcers, the powder being sprinkled on the affected area. Internally it is decocted at about 3-9 g or taken as powder. A gentle, food-grade animal substance, it is typically used as an adjunct within moistening, Yin-nourishing formulas under professional guidance.
Botanical Description
Feng Huang Yi (凤凰衣) is most commonly recorded in Chinese materia medica not as a plant at all but as the thin inner membrane of the hen's eggshell (the chorioallantoic membrane peeled from the inside of a chicken egg after the contents are removed), used as a folk remedy for chronic cough and to promote healing of ulcerations. Some regional sources apply the same name to flower-bract structures of certain ornamental plants, but without a corroborating Latin name the identification cannot be made with confidence. Because the substance is most likely an animal-derived material rather than a plant — and possibly not in standard pharmacopoeial use — the record follows the unidentifiable/non-plant null-pattern.
