Blisters on the lips may be caused by excessive internal heat, poor diet, emotional anxiety, and other factors, requiring timely diagnosis and treatment at a formal hospital. If one does not pay attention to a balanced diet in daily life and frequently consumes spicy and stimulating foods such as spicy strips, hotpot, and blood cubes in chili sauce, it may induce internal heat. If one is in a bad mood or stays up late for a long time during this period, it may exacerbate the internal heat reaction, leading to blisters on the lips. If treatment is not prompt, patients may also experience symptoms such as flushed face and eyes, dark and scanty urine, insomnia with dream-disturbed sleep, appetite loss, dry mouth, and thirst, seriously endangering physical health.
When patients experience excessive internal heat, they need to promptly adjust their diet by consuming more fresh fruits and vegetables, such as lettuce, spinach, and cucumbers. If the body's irritation intensifies, they can take medications like Niuhuang Jiedu Pian, Qingwei San, and Huanglian Shangqing Wan under a doctor's prescription to alleviate the symptoms, which can clear heat and reduce the body's irritation. It is essential to take care of the blistered area and avoid squeezing it forcefully to prevent local infection. During treatment, one should regularly check their health status and adjust the treatment approach as advised by the doctor.
