Here are pages 165-169 (not shown in my post) describing the standard method for preparation of fluidextracts from any plant substance. If the alcohol is evaporated off, it's called an "extract." This was the way pharmacists, more properly called "chemists," adhered to standard practices when preparing prescriptions from herbal remedies.
The doctor who prescribed an herbal fluidextract (or extract) would be assured that the patient would receive a standardized dose, prepared by any pharmacist at any pharmacy. This was legitimate oversight in my opinion.
Yeah it is really a shame that the medical uses of cannabis were swept under the rug for so long - it used to be a standard part of the pharmacopeia as evidenced by that book :) It has so many uses. For pain it is really amazing, it doesn't make the pain go away necessarily, but it makes you feel a lot better and pain doesn't bug you as much. My wife didn't like the prescription pain pills at all and they didn't really make her feel better, but she found marijuana tincture worked way better for her. Added bonus of course that I can whip up our own batches of marijuana tincture at the house in an afternoon... I am not about to create my own batch of hydrocodone anytime soon LOL
Right...the source of pain may persist, but your perception of it can be modulated. I'd rather modulate via the endocannibinoid system than via the opiate receptors.
And congratulations on your expertise as an herbal pharmacist!
