Niu Xueen, chief physician of the Department of Gastroenterology, Henan Provincial Hospital of Traditional Chinese Medicine, said, "From the perspective of traditional Chinese medicine, excessive intake of greasy and sweet food is easy to hurt the spleen and stomach, increase the burden on the digestive system such as the stomach and intestines, and make the human body lose the function of transporting water and dampness, leading to an increase in garbage and wet poison in the body, which makes people's faces appear rotten horns and acne."

Niu Xueen believes that some people think that taking some drugs such as Huanglian Shangqing Pill, Sanhuang Tablet and Banlangen privately will often aggravate the condition. "The fire in the rotten mouth is a' virtual fire', and Chinese medicine is also called yin fire, which is different from real fire. Because the yin in the human body is too heavy at this time, eating drugs that clear away heat and detoxify will aggravate the yin in the body, leading to more and more yin evils in the body. "

Niu Xueen suggested that people with rotten mouths should eat less greasy and sweet food, grapefruit and watermelon.
