Dry and crusty nose is mostly caused by fire in the lungs or dry weather. From the perspective of traditional Chinese medicine, the lungs open the orifices in the nose, and if the nose is dry and crusty, it is usually caused by fire in the lungs, i.e. lung fire. Lung fire is categorized into solid lung fire and deficient lung fire. If it is caused by solid lung fire, in addition to the symptoms of dry and crusty nose, there may also be nasal congestion, sticky phlegm, yellow urine, dry stools and other symptoms. If necessary, you can take Antelope Lung Clearing Pill, Shuanghuanglian Oral Liquid and other medicines under the guidance of your doctor for treatment. If the inside of the nose is dry and crusty due to lung deficiency fire, it may also be accompanied by symptoms such as five heart-heat (heat in the hearts of the hands and feet, and self-consciousness of the heart and chest), cough without phlegm, and low fever in the afternoon. If the clinical symptoms are more obvious, you can take Lily Solid Gold Oral Liquid under the guidance of a doctor to treat it. It should be noted that the dry crust inside the nose, in addition to the lungs caused by fire, may also be due to the dry environment or other diseases. It is recommended to go to the hospital in time. Drugs need to be identified by a traditional Chinese medicine practitioner after the rational use of medication, not to be taken at random.
