Within this formula, Jin Yin Hua and Lian Qiao are acrid, cool, and fragrant. They resolve the exterior, clear the lungs, and resolve toxins. Jie Geng and Niu Bang Zi diffuse the lungs and free the flow of the throat. Bo He and Dan Dou Chi aid in the resolving of the exterior and clearing of heat. Jing Jie Sui further boosts exterior-resolving without causing dryness. Dan Zhu Ye, fresh Lu Gen, and Gan Cao engender fluids and alleviate thirst. In particular, the combination of Jie Geng and Gan Cao is empirically effective for treating sore throat. This formula comes from Wu Ju-tong’s Qing dynasty Wen Bing Tiao Bian (Systematic Differentiation of Warm Diseases) published in 1798.
