Lee Buan Soa

Our story

Lee Buan Soa Dispensary was first established as a small family business during World War II (around 1943) by Mr. Lee Mok Lim and Mrs. Lee Eia See, situated in the Sampantawong area of Bangkok, with "Fishing Brand" as its trademark for more than 70 years. Our best-known product is "Lee Buan Soa Pill (Fishing Brand)", also called "Jia Tung Aee Pill" — a familiar remedy for those with stomach problems and toothache.

The journey to Lee Buan Soa (Fishing Brand)

Milestones & timeline

The beginning
Husband and wife emigrated from China

Mr. Mok Lim and Mrs. Li Earsri Chae Li were a poor married couple living in China. Due to their hardship, they decided to cross the sea to Thailand, hoping to use their knowledge and skills to make a living and provide a comfortable life for their family.
Trok Klantan
Came to live in Thailand

Mr. Mok Lim and Mrs. Li Earsri Chae Li lived in a small shophouse in the Trok Klantan area. They used their knowledge of medicine to produce and trade herbal remedies. Some were sold by the grandfather, while some were given away to the poor who had no money.
World War II
Kindness in wartime

One day, a Japanese soldier came to Grandma for help — he had been cheated out of his money and had not a single baht left. Feeling pity, Grandma gave him some of Grandpa's clothes and a little money, hoping he would survive and return safely.
1943
Received the formula for "Lee Buan Soa Pill"

Filled with gratitude, the soldier — a military doctor in a Japanese army camp — passed on a medicine formula to Grandma to repay her kindness. That formula is today's "Lee Buan Soa Pill (Fishing Brand)". He said: "No Japanese soldier would ever go into battle without carrying this medicine."
Fishing Brand
Trademark registration

A few years later, Grandpa and Grandma registered the "Fishing Brand" trademark — a god sitting and fishing. Fishing requires patience, calmness and perseverance, just like making medicine, which requires care and meticulous attention to produce good quality.
1977
Expanding to Rama II Road

Started a pharmaceutical factory on Rama II Road, Bangkok, on an area of 1 rai, with one modern pharmaceutical plant and one herbal plant, administered by Mr. Chai Theerakarn, the fifth son.
2004
A new factory in Samut Sakhon

Started a new pharmaceutical factory on 8 rai in Ban Phaeo, Samut Sakhon, and received the Good Manufacturing Practice (GMP) certificate in accordance with WHO recommendations from the Thai FDA — successfully passing all surveillance audits ever since.
Today
GMP PIC/S standard

The factory continues to expand on the same site, with automated machinery, a clean-room laboratory, GC and HPLC analytical instruments, and skilled pharmacists — all under GMP PIC/S.
