Hot Pepper

Traditional Use

Primary Actions

• Warms the middle and disperses cold - La Jiao is used for cold-type abdominal pain, vomiting, diarrhea, and sluggish digestion when cold obstructs the middle burner.
• Moves qi downward and promotes digestion - it helps reduce food stagnation, chest or epigastric oppression, and poor appetite when cold and damp impede digestive movement.
• Warms the channels externally - topical or wash-style use appears in folk and regional practice for rheumatic pain, chilblains, and poor local circulation.

Secondary Actions

• Medicinal use of La Jiao is narrower than its everyday culinary use. The fact that chili is common in food does not mean high-dose medicinal use is automatically gentle or appropriate for every constitution.
• Modern capsaicin pain literature often involves standardized topical extracts or high-concentration patches, which should not be confused with simply eating more chili.

Classic Formulas

• La Jiao with Sheng Jiang or Gao Liang Jiang - warming-middle pairings used when abdominal pain, vomiting, or diarrhea reflect cold rather than heat.
• Topical chili preparations or decoction washes - traditional external approach for cold-damp painful joints or frostbite-type lesions.
• Food-medicine use in warming soups or congees - a gentler strategy for cold digestion in people who tolerate pungent foods.

Classical References

• Chinese materia medica references describe La Jiao as acrid and hot, entering the Spleen and Stomach to warm the middle, scatter cold, direct qi downward, and aid digestion.
• Its standard indications center on cold stagnation and weak digestive fire, not on heat patterns.
• External use is also described for wind-damp pain and cold-injury lesions such as chilblains.
