Shanghuo (literally "on fire") is a theory in Traditional Chinese Medicine (TCM) that has not been explicitly supported by Western medicine. Shanghuo has a deeper meaning, referring to a range of generalized symptoms. For example, stomach fire can manifest as stomach pain and dry stools; lung fire can present with hemoptysis, cough, and yellow phlegm; and liver fire can cause irritability, insomnia, and in women, breast tenderness. Fire is categorized into deficient fire and excess fire. In a healthy body with balanced yin and yang, excess fire occurs when yang is excessive while yin is normal. Deficient fire occurs when yin is insufficient, causing yang to appear relatively excessive.

Explanation
Shanghuo has a deeper meaning, referring to a range of generalized symptoms. For example, stomach fire can manifest as stomach pain and dry stools; lung fire can present with hemoptysis, cough, and yellow phlegm; and liver fire can cause irritability, insomnia, and in women, breast tenderness.
"When qi is in excess, it becomes fire." Any symptoms of redness, swelling, heat, pain, a bitter taste in the mouth, dry throat, nightmares, and irritability can be termed "shanghuo".
Fire is categorized into deficient fire and excess fire. In a healthy body with balanced yin and yang, excess fire occurs when yang is excessive while yin is normal. Deficient fire occurs when yin is insufficient, causing yang to appear relatively excessive.
Other Meanings of Shanghuo
"Fire's nature is to flare upwards." Therefore, fire-related symptoms are most often manifested in the upper parts of the body, particularly above the waist.
Fire is considered one of the "six excesses" (liu yin), pathogenic factors. It can be caused by both external and internal factors. External fire can originate from climate and diet, while internal fire is often caused by emotions.
What is the most typical manifestation of externally contracted fire-heat?
The most common is heatstroke, which usually occurs after spending too long in an environment with high temperatures, dehydration, and stuffiness, leading to a rise in body temperature. This is a typical case of externally contracted fire-heat. Generally, endogenous fire-heat is more common than externally contracted fire-heat. For example, in modern times, factors like increased stress, frequent staying up late, and eating spicy food have made endogenous fire much more prevalent than before.
Many people consider shanghuo a minor ailment that can be resolved with some medication or self-regulation. Indeed, in mild cases, shanghuo can be self-regulated. However, for specific populations such as the elderly or individuals with underlying conditions like cardiovascular disease, it should still be taken seriously.
