Every plant has different properties and you have to know the best way of extracting those properties for each plant. If you can afford, there are people who put up herbal extracts and have classes on how to do it. Course it would be best to do it the MH way, but I don't think he's conducting classes on the how to's. http://www.mountainroseherbs
has classes like that. Herbalism is legitimate natural medicine the way God intended medicine to be. "Let food be your medicine and medicine be your food".
We've got to consider fruit can have artificial coloring on the outside since a lot of it is picked green. the best way would to be to find an organic grower and buy in season.
