St John's wort and hormone treatment

Going through breast cancer treatment Hormone therapy

Hi,

I keep finding links to docs on this forum that talk about the evidence for not using St John’s wort whilst on tamoxifen or having an estrogen positive cancer. But all the links don’t work. Could anyone signpost me?

And does anyone happen to know whether the same is true for topical application?

Thanks

Lou

@Purpletrunks  - Hi Lou, you don’t say WHY you are looking at St Johns Wort?? Would it be for its antidepressant properties, or otherwise?? Delly xXx
