Sang Bai Pi (écorce de racine de mûrier) est une plante froide et douce de la médecine traditionnelle chinoise (MTC) connue pour dégager la chaleur des poumons, calmer la respiration sifflante et favoriser la miction afin de réduire l'œdème. Elle est dérivée de l'écorce de la racine du Morus alba et est particulièrement apprécié pour traiter la toux avec mucosités jaunes, l'asthme et les gonflements dus à la rétention d'eau.
