Re: I've been researching comfrey and a few websites are saying Comfrey causes liver damage.

It's false. I have read a lot of the research on it and the people testing it did NOT use the whole herb. The way i see it, you can not test a herb my taking one part out of it in a lab and shooting a massive dose of the one part into a rat and say they know what it's going to do in a human.
