Hi, I was a little doubtful about it be compared to morphine so I tried it on a pulled shoulder arm muscles for three days. All pain disappeared and never came back I had did the same thing to my other shoulder and it took about a year to heal with aspirin and cold packs on daily basis. This could be a potent answer to chronic pain because it is so effective and is so safe with no side effects like addiction. I haven’t tried the extract but my experience with extracts they are even more potent then powders or caps. Amazing stuff!
