Upper Jiāo Harmonization
While both herbs clear Wind-Heat from the exterior, their specialties divide at the organ level. Sāng Yè has a stronger affinity for the Lungs, making it indispensable for dry coughs. Jú Huā has a stronger affinity for the Liver, making it the primary choice for red, itchy eyes and dizziness due to Yáng rising.
The Sāng Jú Synergy: Sāng Yè moistens while clearing, and Jú Huā vents while subduing. Together they form the backbone of the famous Sāng Jú Yǐn formula for early-stage Wind-Heat.
