Pi Pa Ye - Feuille de Loquat - Folium Eriobotryae

Pi Pa Ye (feuille de loquat) est une plante fraîche et amère de la médecine traditionnelle chinoise (MTC) connue pour dégager la chaleur des poumons, transformer les mucosités et harmoniser l'estomac afin d'arrêter les nausées et les vomissements. Elle est dérivée des feuilles de Eriobotrya japonica et est très apprécié pour soulager la toux accompagnée de mucosités jaunes épaisses, la respiration sifflante et l'inconfort de la gorge dû à la chaleur des poumons. Pi Pa Ye dirige également le Qi rebelle de l'estomac vers le bas, ce qui le rend efficace pour traiter le hoquet, les nausées et les vomissements. Sa double action sur les poumons et l'estomac le rend particulièrement utile dans les affections respiratoires accompagnées de troubles digestifs.
