I know in the UK epsom salts is often kept behind the counter. Mabe if you ask the pharmacist at one of the bigger Watsons or Mannings they may stock it. Good luck

Was it a large tub of Epsom Salts you managed to buy?. I have now heard Epsom Salts are difficult to find in HK. I would like to purchase some. Please can you let me know where you bought your's from. Many thanks
