Flatulence of the tongue is usually caused by mental, immune, infectious, endocrine, and microcirculatory disorders. At present, the treatment of lichen planus in clinical practice usually takes the form of drug therapy and life care for relief. If there are no symptoms of lichen planus and it does not affect the normal life, it is not recommended to take treatment. If the symptoms of redness, swelling and pain appear, it is recommended to take topical medication. Topical medications are often used in the form of adrenocorticosteroid ointment, and procaine and prednisolone can also be used to inject into the lesion. Regular use of chlorhexidine and mycophenolate is also recommended to relieve the symptoms of lichen planus by rinsing the mouth. It is also recommended that patients with lichen planus should pay more attention to their diet. It is recommended that they should eat a light diet and avoid the stimulation of inflammation by spicy foods, and eat more fruits and vegetables that are rich in vitamins. You can drink fat sea iced sugar tea twice a day, which can play a role in clearing heat, detoxifying and moistening the lungs, effectively improving the symptoms of lichen planus. Usually, the treatment of lichen planus depends on its severity and the presence or absence of symptoms. When there is no symptom, no treatment can be given, but when it has already affected normal life, it is recommended to take topical medication and pay more attention to diet for relief.
