上火

• Pinyin: shàng huǒ
• Hanzi breakdown: 上 = to rise upward; 火 = fire/internal heat — 上火: fire rising inside the body (TCM); metaphorically, getting heated or angry

Meaning

To develop internal heat; a traditional Chinese medicine concept in which excessive internal fire causes symptoms such as mouth sores, sore throat, or acne. Colloquially also means to get angry or worked up.

Rooted in TCM theory of yin-yang balance. 上火 is triggered by spicy or fried foods, stress, lack of sleep, or emotional upset. Symptoms include sore throat, mouth ulcers, red eyes, nosebleeds, and constipation. In colloquial use it also means to become irritated or flustered. Contrasted with 降火 or 去火 (to reduce internal heat).
