Noelnoel, St Johns Wort is not recommended for people taking various prescription medications, including thyroid medication.

From the PIL of an Holland&Barrett SJW product images.hollandandbarrettima...

Do not take this product if you are taking any of the following medicines:

thyroid hormone: Thyroxine

Whoever is thinking of taking St John's Wort is presumably taking it for depression and/or anxiety?

There is an alternative which they might be interested in - 5-HTP. I wrote about it in this reply to someone else :

I've been taking 5-HTP for about ten years now, and it hasn't caused me any problems. But I do take an extremely low dose (50mg. four days a week).

Thank you humanbean

Yes she is but she’s had a glaucoma op and cannot take conventional anti-depressants. Not sure why. Also, St. John’s wort is looking as though it may have similar side-effects so 5-HTP may be the answer. She’s a scientist and well informed but doesn’t know so much about alternatives to convention

St. John’s wort is another name for Prozac or fluoxetine. Jo xx

Jo,

No - really, it is not. They are very, very different to each other, although what they have in common is that both can be used to treat depression.

This is quite an in-depth overview of St John's Wort:

And this is the UK's NHS page about Prozac/Fluoxetine:
