Description
Xiao Yao San (Free and Easy Wanderer Powder) is the most widely used formula for Liver Qi stagnation with Spleen deficiency and Blood deficiency. When the Liver's free-flowing function is impaired through emotional stress or overwork, Qi becomes stagnant and the Spleen is invaded. The formula simultaneously spreads Liver Qi, nourishes Blood, strengthens Spleen, and harmonizes the middle burner.
