>>I have heard and read different places that an excess of comfrey taken internally has reported caused liver damage. A garden group that I am in got a notice from there headquarters that had a notice that the FDA was considering taking comfrey off the market, in plant form, pill form, etc.

>It seems to me that the studies were done in Australia and were done using extracts of the plant not the whole plant.
A friend was asked by the CSIRO (Aust) to grow some comfrey for them for testing. The research on the "plant" came out before she delivered the plants! Reseach was done on the alkaloids and inferred from research on other heliotope species.
Parsley is more poisionous than comfrey.
