She Tui (Snake Skin)
She Tui (Sloughed Snake Skin); Elaphe Carinata/Taeniurus; Serpentis Periostracum
She Tui is the sloughed skin of a snake, usually of a genus of non-venomous colubrid such as the Rat Snake. She Tui, composed of a number of amino and fatty acids, dispels wind and spasm, both internally and from the skin and can be used for bi-zheng. She Tui has similar functions, but weaker, than those of Bai Hua She/Qi She and Wu Shao She.
