材料：在1206年蒙古国建立前后，蒙古族医与巫的界限尚不很清楚，故卫生保健制度也是比较原始，蒙古国建立后，医事制度逐渐引起统治者的重视，特别是元世祖忽必烈建立元朝后，对医疗保健提出迫切要求。忽必烈为了提高医生医疗水平，淘汰不合格医生，于1272年正式建立“医学提举司”，专门负责太医以及各级医学人才的考校，并负责校勘医藉指导各路医学及辨别药材等。1282年，又正式建立了为太子保健服务的“典医监”等机构。1288年还在地方设立了“官医提举司”，管理医户差役词讼等事务。1292年，于广惠司下建立“回回药物院”，职别从五品，专门管理回回药事，使阿拉伯医学在中国得到更广泛的传播。1294年又建立掌医监及广济提举司，管理修合药饵，以施贫民。至此，元代的医事制度，已基本形成，并有较完整的医疗保健制度。
