Jie Geng is the root of Platycodon grandiflorus, a balloon flower native to East Asia, traditionally employed to clear lung heat, transform phlegm, and promote voice clarity in TCM. Its distinctive saponin-rich chemistry makes it particularly valued for respiratory conditions marked by cough and sore throat, often serving as a directional guide herb in formulas targeting the upper respiratory tract.
