For those of you who have personally benefitted from an acupuncture treatment, confirmation that acupuncture points exist may not surprise you.
However, I always think it is interesting when modern technology enables us to visualize, or even better understand, that which we may already know, at least from the level of our own experience.
In the article, which featured this image and others like it, modern technologies such as MRI (magnetic resonance imaging), infrared imaging, LCD (liquid crystal display) thermal photography, ultrasound and other CT (computerized tomography) imaging methods were used to provide visual representations of acupuncture points on the body.
The acupuncture points in the image above, in such pleasingly vivid color, features the area on the inside of the wrist and includes points along the Lung, Pericardium and Heart meridians.
The theory is that acupuncture points lie along various trajectories that run usually longitudinally through the body. Stimulation of these points with a needle, or with moxabustion, or even an essential oil, serves to benefit not only the organ to which the meridian refers, but also the various bodily functions as well.
Much can be said about how and when to use the various acupuncture points. There are well over 400 points on the body and head, even the ears, each one with its own specific indications.
Some of the functions of the points in this image include the regulation of the heart beat, eliminating night sweats (especially in combination with another point along the Kidney meridian on the lower leg), improving lung function, alleviating insomnia, treating anxiety and subduing nausea.
While this research is in itself interesting, the true value of a study such as this one may lie somewhere within the intersection of these ancient and modern perspectives.
Science, as one of the leading languages of our current culture, seeks to elucidate mystery. As the ancient tradition of Chinese medicine has been, and continues to be, translated into English, so, too, can it be interpreted within scientific terms. Perhaps science can shed light into the mystery of how acupuncture works.
