Htp5 plus St. Johns

Hi all, the lady in the well known herbal shop : ) would not sell me 5htp because I take St. John' s wort. I got some 5htp anyway and intend to be sensible with it.

Anyone take these together ? These are for the use,. in my case, for an antidepressant by the way.

If you have experience of these and can answer TIA.
