Vomiting results from the Stomach failing to descend and qi rebelling upward. Repletion types arise from external pathogens, food stagnation, phlegm-fluid retention, or Liver qi invading the Stomach; vacuity types arise from Spleen-Stomach weakness or Stomach yin insufficiency.
Key differentiation: Cold vomiting produces clear fluids with cold aversion; heat vomiting produces sour bitter fluid with foul breath; food stagnation vomiting has sour rotten smell with belching; phlegm-fluid vomiting produces clear watery phlegm.
