Answer: (B)

Licorice (Gan Cao) serves as the harmonizing herb in Xiao Yao San, and it is used in a smaller amount to balance the stronger, main ingredients. In this formula, the principal herbs are typically dosed at about 9 g each to move liver qi and nourish blood. Gan Cao is included at 4.5 g to smooth and moderate the overall effect, preventing harshness or excessive stimulation from the other herbs. This smaller amount allows Gan Cao to harmonize the formula, support digestion, and reduce potential irritation without overpowering the key actions of the other herbs. That’s why the herb with a 4.5 g dosage is Gan Cao.
