In Si Jun Zi Tang, what is the dosage range for Bai Zhu?

• A. 3-6 g
• B. 6-9 g
• C. 9-12 g
• D. 12-15 g

Answer: (B)

Tonify qi and strengthen the Spleen while balancing dampness. In Si Jun Zi Tang, Bai Zhu serves as the main Spleen qi tonic and damp-drying agent, and its dose is kept in a middle range to harmonize with the other herbs. A 6-9 g amount provides enough Spleen qi support to improve digestion, energy, and resistance to dampness without tipping the formula toward excessive drying or overpowering the other ingredients. Using less than this (3-6 g) would under-tone the Spleen qi, while more than this (9-12 g or higher) could disrupt the formula’s balance and damp-drying effect.
