Oral lichen planus is an intractable chronic inflammatory lesion with dyskeratosis, appearing more commonly on the buccal mucosa. Here we describe a case of oral lichen planus starting on the bilateral buccal mucosa in a 70-year-old female patient that showed great improvement. The patient's condition gradually improved after treatment with cepharanthin, an alkaloid agent extracted from Stephania cepharantha Hayata. A review of some additional literature pertaining to probable mechanisms of action is included.
