I put a packet of comfrey in the refrigerator to stratify over over two years ago. For the reasons of conflicting information is why I haven't planted them. There is one type from seeds and one from root cuttings, and I believe one of the two types can become invasive.
I have a bottle of a healing tincture that I've had for years and never used it. It's called Bacteria Buster. It contains comfrey extracts of the leaf and stem.
