Traditional Use

Primary Actions

• Dries dampness and disperses cold in the middle burner ... Cao Guo is used for abdominal fullness, cold-damp stagnation, poor appetite, foul turbidity, and a heavy obstructed digestive center.
• Warms the Stomach and stops nausea or vomiting ... its strongly aromatic warming nature makes it useful when retching and heaviness arise from cold-damp obstruction rather than from heat.
• Cuts malaria and transforms miasmatic turbidity ... traditional use extends to alternating fever-chills and epidemic damp-filth patterns where aromatic penetration is prioritized.

Secondary Actions

• This page should stay on the large dried capsule of Cao Guo and remain distinct from Bai Dou Kou, Hong Dou Kou, and other cardamom-family trade lanes.
• Its function is stronger, hotter, and more damp-turbidity-focused than the gentler digestive aromatics often grouped nearby in commerce.

Classic Formulas

• Da Yuan Yin ... the signature epidemic damp-turbidity and malaria-context formula in which Cao Guo penetrates membrane-source obstruction.
• Cao Guo Yin and related malaria traditions ... classic use when foul dampness, obstruction, and alternating fever are central.
• Cold-damp vomiting combinations with Hou Po, Ban Xia, or Gan Jiang ... practical middle-burner strategy when heaviness, nausea, and distension travel together.

Classical References

• Traditional herbology places Cao Guo among the strong aromatic dampness-transforming herbs that dry cold turbidity and address miasmatic obstruction.
• Its malaria association is part of the older damp-filth tradition rather than a modern isolated antiplasmodial claim.
