In 1937, Mr Tan Siow Meng, a renowned Traditional Chinese Medicine practitioner, developed a recipe for a medicated oil and named it Three Star Brand (星標).

​

Believing deeply in the benefits that it offers, Mr Tan along with his son, Mr Tan Chor Kiang, began sharing the oil with neighbours and friends. The product, currently marketed by See Hai Tat Medical Hall (Singapore) Pte Ltd, eventually became a household name, making its presence as Singapore's very own medicated oil.

In 2018, we were awarded the ISO 9001:2015 certification, and we also launched our own Traditional Medicated Patches and Aromatherapy Medicated Oil. Today, we take pride in our wide range of products, which include Mozzie Free, Aromatherapy Roll-On, and Aromatherapy Balm, all of which are infused with naturally-derived botanical scents.
