When patients have dryness and crusting in the nasal cavity with pain, some oil-based nasal drops, such as compound mint nasal drops, can be used in the nasal cavity to moisturize and protect the nasal mucosa and improve the dryness of nasal mucosa, etc. When there are more dry crusty secretions attached in the nasal tract, the dry crusty secretions can also be cleaned appropriately. If the dry crust is excessively dry or adheres closely to the nasal mucosa, it can be removed gradually after nasal moisturizing with mint nasal drops. In addition, patients can also take some oral Chinese medicines that have the effect of clearing heat and detoxifying, such as Yiqing capsules, Niuhuang detoxification tablets, etc., which can improve the symptoms of nasal dryness and fire to a certain extent. If the congestion of the nasal mucosa is more serious, or if there are more purulent dry crust components, further oral antibiotic medication can also be administered, and patients can also adhere to the daily use of saline for nasal irrigation treatment.
