Dry and painful nasal cavity may be caused by dryness and nasal mucous membrane erosion caused by fire. You can use compound mint nasal drops or apply an erythromycin ointment to the nasal cavity, both of which can play a role in lubricating and moistening the nasal cavity. If there is a large amount of scab covering the nasal cavity, you can clean it with a physiological sea saline spray. Dry and sore throat may also be related to fire, manifesting mainly as dry and sore throat and laryngitis. You can use heat-clearing and detoxifying drugs, such as Yiqing capsules and compound baicalin tablets, which can effectively relieve the symptoms. You should pay attention to a light diet, ensure sleep and drink more water. You can also drink water with honeysuckle and Luo Han Guo, which can remove fire and achieve the effect of clearing heat and detoxification.
