Overview
White Atractylodes, or Bai Zhu, is a fundamental herb in Chinese medicine for tonifying the Spleen Qi. It is used to address digestive weakness, eliminate excess fluid (dampness), and stabilize the exterior to stop spontaneous sweating. It is a key ingredient in many classic formulas for digestive and metabolic health.
