Lung heat may cause nosebleeds in patients. According to Chinese medicine, the lungs and the nose are connected, and if a patient has lung heat, it may lead to dryness of the nasal mucosa, mucosal erosion and ulceration, which may easily induce bleeding from the submucosal vessels. It is common to have respiratory tract infection with high fever and other manifestations, often with nasal bleeding. For this condition, patients are advised to visit an ENT clinic to check the condition of the nasal mucosa while treating pulmonary fever. You can use compound menthol nasal drops to keep the nasal cavity moist, or you can rinse the nasal cavity with saline to also keep the nasal cavity moist. Patients are advised to eat more vegetables and fruits, take more vitamins and eat Sydney appropriately. If the local erosion of the nasal cavity is obvious, erythromycin eye ointment or recombinant bovine basic fibroblast growth factor gel can be applied to the erosion and ulcerated area of the nasal cavity to promote wound healing and reduce bleeding.
