Which set of herbs are common to Yin Qiao San and Sang Ju Yin?

• A. Jie Geng, Lian Qiao, Bo He, Gan Cao, Lu Gen
• B. Jin Yin Hua, Lian Qiao, Bo He, Jie Geng, Lu Gen
• C. Jie Geng, Lian Qiao, Bo He, Gan Cao, Lu Gen
• D. Jie Geng, Jin Yin Hua, Bo He, Gan Cao, Lu Gen

Answer: (C)

Both formulas focus on clearing heat and releasing exterior wind-heat with an emphasis on the throat and lungs. The herbs that appear in both are Jie Geng, Lian Qiao, Bo He, Gan Cao, and Lu Gen. Jie Geng helps open the throat and support lung function; Lian Qiao clears heat and toxins; Bo He cools and disperses exterior wind-heat; Gan Cao harmonizes the prescription and soothes the throat; Lu Gen clears heat from the lungs and helps generate fluids. Jin Yin Hua is a primary herb in Yin Qiao San but not in Sang Ju Yin, while Sang Ye and Ju Hua are characteristic of Sang Ju Yin, so they’re not common to both.
