heckling from the back!
This must be the stuff :-
Phenolphthalein was previously used as a laxative but is no longer authorised for sale in the UK as it may cause cancer.
Sibutramine was previously used to treat obesity but no longer licensed due to its association with an increased risk of cardiovascular side effects such as heart attack and stroke.

I remember using Phenolphthalein when I worked in a chemistry lab for something - some sort of titration indicator ?
Yes, as above.....
Phenolphathalein *was* the 'active' ingredient is ex-lax, if I remember correctly. It certainly featured (at a very low dose) in some home-made laxative products......which worked very well.
