Herbs - empty stomach or not?

[Guest guest]

Is there a general rule for taking herbs - on an empty stomach or with

meals?

I am taking Samento & homeopathic Cat's Claw & have been specifically

told those should be on an empty stomach. But I am also taking Spiro &

Lymestat, plus two tinctures - one for anxiety & one for liver support.

And Resveratrol is a herb, so same applies there.

And how close to vitamin supplements should herbs be taken?

Any help would be greatly appreciated.
