"Bamrungchat Satsanayathai" or "Baan Mowaan" or "Doctor Waan's House" is a colonial style building located in the Giant Swing area of Bangkok. It is an inheritance from Mr.Waan Rod-Muang, a Thai traditional doctor, who lived during 1870-1945. Currently owned by his great grandchildren, the building has been both a home and a place where Mowaan's recipes of traditional Thai medicine were created and recreated for over four generations. Inside the building are full of historical relics that tell stories of the past. Additionally, Mowaan's longtime famous Ya Hom continues to be produced, according to Mowaan's four original recipes which are now a century-old. The production process has been richly preserved. Even the tools that are being used are the originals that have served our loyal customers for over a hundred years.
