Which herb is noted for raising blood pressure and promoting qi by raising SP yang?

• A. Zhi Shi (correct)
• B. Mai Ya
• C. Mang Xiao
• D. Tong Cao

Answer: (A)

The herb being tested is one that primarily moves and uplifts qi, especially in the middle burner, to restore the SP’s function and promote overall qi flow. Zhi Shi has a strong qi-moving action that breaks up stagnation and guides qi upward, which helps the spleen’s qi rise and function more effectively. When SP qi is constrained by stagnation, lifting and directing qi upward can improve the body's energetic tone and, in patterns where deficient qi affects circulation, can manifest as a rise in energy and blood pressure. This upward-qi effect is why Zhi Shi is noted for promoting qi and supporting SP yang.

Mai Ya mainly aids digestion and reduces food stagnation but doesn’t have the same pronounced qi-moving and upward-raising action as Zhi Shi. Mang Xiao is a purgative that softens hard stools and drains dampness, not about elevating SP qi. Tong Cao tonifies and harmonizes, including aiding SP qi, but its primary role is milder tonification and harmonization rather than the strong qi-upward movement seen with Zhi Shi.
