re: discontinuation of epsom salts(?)

I was shocked to discover that Epsom Salts are no longer available in the U.K, according to my local pharmacist in London.
Is this right?
Does anyone know why?
Does anyone know anywhere in the U.K {preferably London) I can get Epsom Salts ?
Also can somebody tell me how to use apples to open the bile ducts instead of Epsom Salts ? How many do you take for how long? This is in case I cannot get hold of any epsom salts. Tweet
