Herbal medicine in oral lichen planus

Oral lichen planus (OLP) is a common chronic inflammatory and T cell‐mediated autoimmune disease in which the oral mucosa, tongue, and gingiva are involved. Different treatments have been suggested to reduce the symptoms of this disease. Currently, a common treatment for OLP is the use of corticosteroids as the gold standard, although they have considerable side effects. The chronicity of the disease needs the long‐term use of these drugs with ensuing side effects. Therefore, various studies have been done to find an alternative and effective treatment. The use of herbal medicine as an alternative therapy with antioxidant and anti‐inflammatory properties seems promising. Hence, this review study was done to summarize the efficiency of different herbal medicine in the treatment of OLP.
