from a human use point of view...I use it on myself, after fracturing a vertebrate and tearing ligaments in my back, and cracking my shoulder blade, I didn't need painkillers after two weeks! and am/was a lot more mobile than what i thought i would be, the doctors is pleased with the healing though its hard to tell exactly how much difference its making as only have a scan every 6 weeks but from a pain perpesctive i think it has helped me hugely and would definitely be using it my horse if ever needed
