In Si Jun Zi Tang, what is the dosage range for Zhi Gan Cao?

• A. 1-3 g
• B. 3-6 g
• C. 6-9 g
• D. 9-12 g

Answer: (B)

Zhi Gan Cao in Si Jun Zi Tang serves as the harmonizer, smoothing and guiding the stronger qi-tonifying herbs (Ren Shen, Bai Zhu, Fu Ling) so they work together rather than clash. Using a moderate amount—3 to 6 grams—provides enough licorice to unify the formula and support the spleen without overpowering the other herbs. Too little (1–3 g) may fail to harmonize the blend, while too much (6–9 g or more) can tilt the balance toward excessive sweetness and dampness and may bring unwanted licorice-related effects.
