The basis for this theory is that the skin was the original feeding system for humans when they were just simple-celled organisms. This was before we developed more complex organs like the digestive tract. The only way to get nutrients was through cell walls. Sweat and fluids below the skin oxidize chemicals by acting as electrochemical generators, breaking down and absorbing elements of copper and iron into the body.
Investigators are also trying to figure out how to quantify the effects of crystal healing. Proponents say that measurements of crystal phenomenon such as auras, vibrations and frequencies are not presently testable. Opponents are sure these occurrences are not measurable because they aren’t real. But frequency-based technologies are already in use. Ultrasounds, cauterization tools and microwave diathermy (electrically induced heat) machines all use various frequencies to accomplish their tasks.
