The Museum of Thai pharmacy is somewhere which I had read about on the Internet and was pretty close to where I was going - so I wondered down a side road...
It is on the third floor of the Pharmaceutical Association of Thailand under Royal Patronage Building at 40 Soi Santisuk, Sukhumvit 38 Road.
In the Museum of Thai pharmacy there are apparently a number various topics - the Birth of Pharmacy, the Evolution of Oriental Pharmacy and Basic Wisdom, the Evolution of Western Thai Pharmacy and the Evolution of Herbs and Natural Products - thanks Richard Barrow.
