I also like james Green's "Herbal medicine Makers Handbook." I have the old edition...he says that comfrey and other mucilagionous herbs turn nto something that looks like slugs in alcohol.I wonder whetehr it would work to juice the whole fresh root and then combine the resulting juice with brandy o other highquality alcohol to preserve? never tried it; I only use comfrey root externally at this poin except for an occasional chop on a fresh root 9had lover hwo was really, really into eating it), and for preservation purposes I make an oil-based salve.

thank you!
