Dawn, your method will not work for 2 reasons. First, your medicine needs to be decarbed (the carboxyl group removed) or the THCA won't be the THC you desire, although some people medicate with unactivated materials in an effort to get relief from inflammation and pain without psychoactive effects. After the decarb, then you must extract the actives. Water will not do this. Actives are volatile oils and dissolve in non-polar solvents, like dissolves like, or you can use grain alcohol which has both polar and non-polar properties which will put you in the green dragon/tincture/qwethanol hash area. I recommend BadKittySmile's thread for info on decarbing and processing edibles, her master thread on this is over at Grass City.

"Decarbing is a touchy issue for many folks, some know they need it but don't know the
methods and practices that cause decarbing, some aren't aware of it at all, others think
it's unnecessary and 'know' they get some amount of effect from eating bud on its own,
here's why: some herb, if it's old, commercial, over-dry, whatever the reason, for a variety
of reasons, some herb is already partially, or even full decarbed. The process begins
happening, very gradually, the moment you cut a plant down and begin depriving it of
water. The older the bud is, and the drier it gets, the more carbon dioxide and water vapor
is released, and the closer it is to removing the carboxyl group. It's something that is
almost never discussed publicly, but is frequently known in professional kitchens.
The fresher the herb, or the more moist the storage conditions, the more necessary and
extensive the decarbing process needs to be. Loose hash, separated from plant matter,
in general needs a bit less decarbing. With herb, depending on the age, I decarb for a full
20 minutes after the preheat, rather than including that warm up in my 20 minute time
frame.
A food dehydrator works just as well, if not better than heat at decarbing, it reduces the
risk of damaging your product with excessive heat. It's hard to tell when your decarb is
completed when using heat, usually gently browned herb is a good sign but it often
means you've taken it a hair too far, and some material in the middle may not be
completely decarbed."
