The Golden Shield for Pregnancy
In TCM obstetrics, "Restless Fetus" is often caused by Spleen Deficiency (failing to hold) or Internal Heat (disturbing the Blood).
Dynamic: Bái Zhú strengthens the Spleen to provide stable "earth" for the fetus, while Huáng Qín cools the "fire" that might destabilize the uterus. This pair is the gold standard for "Calming the Fetus".
Relative Action Intensity
Balancing the cooling nature of Huáng Qín with the warming tonification of Bái Zhú.
