Has anybody grown and used this for their compost? It is more prolific and not invasive like regular comfrey.

We have and have a ton of it on our farm. It is not invasive but will still spread if the soil is disturbed. It grows prolifically and produces a lot of biomass. If you disturb the soil, just a 1/4" of root will start a new plant. It's impossible to kill it. It also gets PM every year.

So pros and cons for sure but it's an interesting plant.

Comfrey is considered to be very carcinogenic, and comfrey products have been banned. Try not to come into contact with any part and very careful handling it.

Gray, can you share your source of information on this please? I've heard it can have mild toxicity to mammals but nothing regarding high levels of carcinogens.

All I can find was 4 cases of people drinking large amounts caused liver damage.
The other I can find is a very large dose of an isolated compound might have caused cancer in rats

Like Tad said, it is hard to get rid of.
