There are a lot of useful plant based treatments that are NOT pharmaceuticals. Things like high blood pressure, cholesterol, blood sugar, repairing adrenals, the list goes on, can be healed/repaired through these herbs. These non-pharmaceuticals potentially don't carry risks or side effects either like the big pharma stuff. FDA approved drugs can be very dangerous. Tylenol kills a lot of people!
Also, ART might help your Frozen Shoulder without resorting to using drugs. I was having some issues with my shoulder (scar tissue), matter of fact I am getting a my 5th treatment today, that have been pretty much resolved through using ART, Active Release Therapy. The treatment isn't very pleasant but the results are remarkable. At least for me. Of course the person treating you should be well informed in the technique. The lady that treats me teaches ART to other doctors so she obviously knows what she's doing. Anyway, take that tidbit for what it's worth.
