Which of the following is an ingredient in Ban Xia Hou Po Tang?

• A. Ban Xia
• B. Gan Cao
• C. Ren Shen
• D. Bai Zhu

Answer: (A)

Ban Xia Hou Po Tang targets a plum-pit sensation caused by stagnation of qi with phlegm. The key action is transforming phlegm and moving qi so the stuck feeling in the throat can be relieved. The principal herb in this formula is Ban Xia, a pungent, warm tuber that directly dries phlegm and guides rebellious qi downward. Its presence is what defines the formula, because transforming phlegm and directing qi are the core effects needed here. Hou Po supports this by dispersing qi stagnation in the chest and helping phlegm move; the other herbs listed are not part of this standard formulation, so they’re not the ingredient being asked about.
