Xiao Tong Cao … Classic Formulas
Xiao Tong Cao · Medulla Stachyuri et Helwingiae
Primary Actions
- Promotes urination and clears mild damp-heat ... Xiao Tong Cao is used when urinary difficulty is present but a gentler pith herb is desired.
- Unblocks lactation ... its postpartum use overlaps with Tong Cao-type logic when breast channels are constrained and milk flow is scant.
- Acts as a narrower substitute lane related to Tong Cao ... useful for fluid movement, but not identical to Medulla Tetrapanacis.
Classic Formulas
- Postpartum lactation-opening pairings with Wang Bu Liu Xing and Luo Lu ... practical galactagogue logic.
- Mild heat-strangury combinations with Hua Shi or Che Qian Zi ... urinary-opening strategy.
- Tong Cao-family fluid-moving use in breast and bladder constraints ... the realistic classical lane for Xiao Tong Cao.
Classical Text References
- Traditional summaries describe Xiao Tong Cao as sweet, bland, and slightly cold, entering the Lung and Stomach to promote urination and lactation.
- Commercial and botanical surveys show that Tong Cao names have historically covered more than one pith source, so this narrower Xiao Tong Cao page should remain identity-conscious.
