Formula祛湿剂· 清热祛湿

二妙散

Èr Miào Sǎn

Two Marvels Powder

From Zhu Danxi's Essential Methods, the foundational formula for lower-burner damp-heat. Only two herbs: Huang Bai clears heat and dries dampness as lead, Cang Zhu fortifies the Spleen and dries dampness as support — mutually reinforcing, marvelous in their simplicity (hence 'Two Marvels'). The ancestor formula of San Miao San and Si Miao San.
