Our company

Our company Tai Tong Ah Company Pte Ltd (大东亚私人有限公司) manufactures high quality traditional Chinese medicinal products under the “Double Prawn” (双虾标) brand.

Tai Tong Ah was founded by the late Mr. Yeoh Liew Kung (杨柳江), an experienced Chinese physician, who had come to Singapore from South China in the 1930s. The business started in the 1950s when Mr Yeoh produced the first few bottles of Double Prawn Herbal Oil in his home using a secret formulation passed down from his ancestors. The product proved to be a hit with users because of its great efficacy in treating a range of common injuries and skin diseases. As word spread among satisfied users, Mr Yeoh and his wife decided to start a company to produce Herbal Oil and several other TCM products. Presently, the company that he founded, Tai Tong Ah Company Pte Ltd has 2 main products under the Double Prawn brand, namely Herbal Oil (青草油) and Rumagon (风湿油).

Tai Tong Ah has come a long way since the early days when production was done by hand at home by Mr Yeoh and his wife and children. Over the years, automation was gradually introduced and quality control processes put into place. The company moved into its first factory in Genting Lane in 1979 and then relocated to Pasir Panjang Industrial Park in 1993. It is now located at the Tai Seng Industrial Park. In 2008, the company received certification for Good Manufacturing Practices (GMP) from the Singapore Health Sciences Authority (HSA).

Tai Tong Ah is committed to delivering high quality products to our customers. We use principles of modern scientific processing in combination with traditional formulation of Chinese medicines in our manufacturing processes. Quality assurance is implemented throughout the entire production process, following the best practices of GMP. Our products are therefore safe, consistent and effective. We have received the approval of the US Food and Drug Administration (FDA) for import into the United States as well as import licences for China and many other countries.

Double Prawn Brand TCM products are well accepted by consumers in Singapore, Malaysia, China, Thailand and Hong Kong for many years. More recently, our market has expanded to countries such as the Philippines, Indonesia, Vietnam, Australia, South and Central Africa and the United States of America.
