Re licorice, it depends what you're using it for. If you're a man, and need to get erections, there may be a problem (which may not happen with DGL type - typically used for healing ulcers, mucosal linings and entire esophageal intestinal lining, great in combo w/ raw cabbage - research this!). If you're a man like I who's not having any sex anyway and is just trying to heal, erections aren't so necessary right now and the actual root or powdered root w/ the "g" of dgl still in it is an excellent tonic.
btw, I regularly consult at least one of the books being sold there, and strongly recommend it:
