Pu Ji Xiao Du Wan, or Universal Benefit Teapills, is a classical TCM formula traditionally used to clear Heat and resolve Toxicity, particularly for conditions affecting the head and face such as swollen, painful throat, red eyes, and fever with swelling. It is commonly indicated for Wind-Heat invasions with Toxic Heat accumulation, which in TCM terms corresponds to acute inflammatory conditions in the upper body. This formula is especially well-regarded for addressing symptoms like swollen lymph nodes, facial swelling, and sore throat associated with exterior Heat pathogens.
