新加坡中医药促进会于1957 年成立，初期会员不多，会务活动有限，直到1972 年会务改革，广招会员，提拔新人，扩大会务活动，制定两项目标，第一项发扬中医中药，培训中医师接班人。第二项开展慈善门诊医疗服务，为患疾病贫苦病人提供施医赠药。为实现此目的，促进会开始策划筹办“两年制针灸学习班”，招生反应热烈，学习中医中药的浪潮急增，因此促进会制定四年制“中医全科学习班”，并干1973 年宣告成立中医学研究院，由资深老中医陈占伟医师担任首任院长。学习中医理论与临床并重，互相结合，於是促进会于1974 年设立首间慈善门诊医院既“大众医院”。
Singapore Association for promoting Chinese Medicines was established in 1957 with a small pool of members and limited services. Through the restructure in 1972 together with membership drive and service expansion efforts, two goals were set for the association, i.e. the promotion of Chinese Medicine through the identification and development of new Chinese Physicians, and the provision of low cost medical care to the sick and needy. To achieve the goals, a tow year acupuncture course was started with overwhelming response. This has led to the progression of the four-year Chinese Medicine Programme and the establishment of the Institute of Chinese Medical Studies led by Mr Chen Zhan Wei as the first President of the Institute. The efforts to link both theory and practice led to the formation of the first Public Free Clinic by the association in 1974.
The Public Free Clinic services to the sick and needy from all strata of society and races has been well received by many, including several philanthropists. To meet the increasing need for medical care, the building at 25A Geylang lorong 22 was bought over and refurbished into a branch clinic in 1997. A subsequent branch was set up at Block 245 in Tampines in 1999. As the need for the clinic’s services continued to increase, the Geylang lorong 22 branch was sold and a 7-storey new building at 10,lorong 9, Geylang was acquired by the society to become the headquarters of the public Free Clinic. The Public Free Clinic, the Institute of Chinese Medical Studies, The TCM Acupuncture Studies has continue to hear fruit under the passionate commitment of the committee members and the leadership of President Sia Bak Chiang.
