Some people often experience dry lips, red and itchy corners of the mouth, and even erosions, thinking it's caused by "heatiness." It may be angular cheilitis caused by a deficiency of B vitamins.
People who frequently suffer from angular cheilitis should pay attention to consuming more foods rich in B vitamins in their diet, such as some cold-mixed vegetables, like fresh green vegetables such as mixed salads, cucumber salads, and spinach salads. They can also often eat a bean rice mixed with soybeans, black beans, mung beans, and various other beans, and have an additional fruit meal between lunch and dinner. In addition, millet, milk, carrots, soy products, eggs, and animal liver are all foods rich in B vitamins and can be eaten in appropriate amounts.
If symptoms of dry, cracked corners of the mouth and itching appear, do not lick them with your tongue. Although this can temporarily make the lips and corners of the mouth feel moist and comfortable, the saliva will evaporate quickly. Not only does it not solve the problem of dryness, but it also brings microorganisms in the saliva to the cracks, causing bacterial infections and aggravating the inflammation of the corners of the mouth.
