源自中医

"Shanghuo（heatiness）" is a unique concept in traditional Chinese medicine.

“上火”是传统中医中一个特有的概念。

Traditional Chinese medicine categorises food as 凉 lèung (“cooling”), 热气 yiht hei (“warming”) and neutral – and practitioners use the nature of the foods to balance the body’s yin and yang.

传统中医把食物分为凉性，热性和中性——医生们则用这些食物的特性以平衡人体的阴阳。

TCM describes heaty foods as having the ability to warm and improve circulation, dispel cold and stimulate the body. When these foods are taken in excess, （yang is greater than yin, your body will generate too much heat）heatiness is caused, resulting in symptoms such as fever, sore throat, mouth ulcers, acne, excessive thirst, redness of the skin and irritability.

中医认为，热性食物具有保暖、促进血液循环、驱寒和激发身体的功能。当这些食物摄入过量（体内的阳压过阴时，你的身体会产生过多的热气），会导致“上火”的现象，引发发烧、喉咙痛、口腔溃疡、痤疮、极度口渴、皮肤发红和易怒等症状。
