保元行创办人丁文琦中医师自1942年在一间小店铺里治病救人，现在保元行已发展成诗巫家喻户晓的中西药品共备的药行。保元行主要经营各类中药、草药、成药的销售，也继续专门为顾客看诊医病，售卖自家研制的产品，其中最热门的是畅行砂捞越70年的【鹿标申功水】。
自90年代开始，保元行对全部自家药物进行注册，于1998年建设了在东马第一间得到政府《良好药品生产规范》 (Good Manufacturing Practice – GMP) 承认的药厂，开始生产符合卫生部要求的药品，维护消费者的健康安全保障。
至今，自家研制生产的成药包括《鹿标申功水》、《鹿标天真膏》、《鹿标铁打止痛水》、《鹿标止咳薄荷水》、《鹿标轻微刀伤止血药水》、《鹿标喉痛散》、《鹿标六畜散》、《堃生杏仁露》、《堃生氏去风药酒》、《羊标石淋消茶》。
