This is a great point for humans and canines. I have used it on my senior clients with good results and now there is science behind it ..
GB37 has been used for the treatment of eye related disorders for over a thousand years. The advent of functional MRI imaging has allowed for researchers to measure the specific regions of the brain activated by acupoint stimulation. Clear evidence from this study demonstrates that GB37 acupuncture needle stimulation activates areas of the brain responsible for vision. Researchers carefully noted that the activation of the visual cortex lasted longer than expected following the acupuncture point stimulation. They also referenced this lasting effect as the “sustained effect of acupuncture” and note that future study designs should take into account acupuncture’s ability to make lasting changes. The researchers note that some studies seek to measure an instant on and off effect rather than measuring the duration of acupuncture’s physiological effects.
