Round Cardamom Fruit … Classic Formulas

Bai Dou Kou · Fructus Amomi Rotundus

Primary Actions

  • Transforms dampness and moves qi - Bai Dou Kou is a classic aromatic herb for heavy, stagnant middle-burner patterns with bloating, chest oppression, and poor appetite.
  • Warms the Stomach and stops vomiting - it is especially useful when cold-damp or turbid dampness causes nausea, retching, or epigastric fullness.
  • Opens the middle burner and improves digestion - its fragrant volatile oils are traditionally used when food sits heavily and the patient feels no hunger.
  • Treats early damp-warmth with damp predominance - it appears in formulas when heaviness, chest stuffiness, and lack of appetite are more prominent than high fever.

Classic Formulas

  • San Ren Tang - classic damp-warmth formula using Bai Dou Kou with Xing Ren and Yi Yi Ren when dampness obstructs the upper and middle burner.
  • Damp-obstruction digestive formulas pair Bai Dou Kou with Huo Xiang, Chen Pi, or Sha Ren for nausea, poor appetite, and epigastric fullness.
  • Cold-damp middle-burner formulas combine it with Hou Po, Gan Jiang, or Cang Zhu when the Stomach is heavy, cool, and vomiting-prone.

Classical Text References

  • Ming Yi Bie Lu records Dou Kou among the aromatic digestive herbs, and later materia medica distinguishes the imported round-cardamom types from rougher cardamom relatives.
  • Traditional herbology consistently emphasizes that Bai Dou Kou is warm and fragrant but should be added late or taken as powder to preserve effectiveness.
