中成药是我国医药学宝库中的重要组成部分,临床应用相当普及。但遗憾的是,中成药说明书上一般都未注明“有效期”或“失效期”。笔者在临床工作中,常需开某种中成药给病家自服,病人服用时,发现药丸大都变了色,个别中成药甚至出现霉变现象。 Chinese medicine is an important part of the treasure house of Chinese medicine, and its clinical application is quite popular. However, unfortunately, the “expiry date” or “expiration date” is generally not specified in the Chinese patent medicine brochures. In the clinical work, the author often needs to open a certain proprietary Chinese medicine to the patient’s self-service. When the patient takes it, he finds that the pills have mostly changed color, and individual Chinese patent medicines have even appeared mildew.
