Which herbal teas are OK?

[Rubberyduck]

So I am currently drinking camomile tea before bed. Although I believe I cannot drink it too often (whatever that means). I have some red berry tea in the cupboard which has raspberry in it. I know raspberry leaf is a no no but if it doesnt state raspberry leaf is it OK? Its so confusing.....

raapbaerry is fine, I’m not aware of any being a problem except maybe possibly raspberry leaf, which is different

I've read no more that 4 cups of herbal tea a day.

But I suspect that's made up... I can't see how hot water and mint leaves can do anything bad, considering how little goes in the tea vs day, having a herby salad.

OK thanks. Theres no indication it has raspberry leaf in it so I assume it's fine
