In Chinese medicine, because the spleen is open to the mouth, stomach, heart, kidneys, etc., the qi of the internal organs also follows the meridians to the mouth, so the abnormal smell in the mouth is a reflection of the malfunction of the above-mentioned internal organs or other internal organs pathology. Light mouth refers to the loss of taste in the mouth, light and tasteless, or unable to taste the taste of food. Many diseases can cause the mouth light. Etiology The lightness of the mouth is most often seen in the initial or receding stages of inflammation, especially in inflammation of the digestive system.
