口腔溃疡为一常见病，中医治疗除内眼中药外，常用散剂吹敷。但药物受口腔唾液的冲刷作用，不易牢固附着患处，以致局部药物浓度低，作用时间短，影响疗效。为了适应口腔用药要求，将本院口腔科临床常用的口腔溃疡散改制成膜剂，临床运用多年，疗效明显。1药物处理：天然牛黄、 Oral ulcers are a common disease. Traditional Chinese medicines are usually used as a topical medicine in addition to internal eye medicines. However, drugs are eroded by saliva in the oral cavity and are not easily attached to the affected area.

The clinical application has been effective for many years. 1 drug treatment: natural bezoar,
