Patients who frequently suffer from oral ulcers can appropriately drink some herbal teas to clear internal heat, such as honeysuckle tea or chrysanthemum tea, which are good choices. It is important to drink plenty of water. If you frequently have oral ulcers, it is suggested that patients visit a hospital to diagnose the causes of the oral ulcers, identifying what leads to them. Because recurrent severe oral ulcers can often be caused by systemic diseases, such as systemic lupus erythematosus or other diseases, which may lead to oral ulcers. Only by identifying the specific underlying causes can effective treatment be achieved. Additionally, oral ulcers may also be related to the patient's diet and lifestyle. Some patients may also experience ulcers due to high work stress, tension, or fatigue, and the long-term use of certain medications can lead to recurrent oral ulcers.
