In regards to nutritional deficiencies, I bought myself a testing kit from Standard Process. It contains over 100 glass vials of whole food supplements, that I place on the body when feeling the pulse. They correlate perfectly with Chinese dietary therapy, and use the theory of "Like cures like." For instance, if the pulse of the kidney is deficient, I place the supplement called Renafood on the person, and the subtle energy of the supplement interacts with the subtle energy felt in pulse. The pulse will change nearly instantly. If its the wrong supplement, then I use another until the pulse is balanced. Same with emotional supplementation. Let's say a person is experiencing bouts of anger, and the liver pulse is rapid and full. I test with a supplement called Livaplex, and the majority of the time, the agitation will calm, and pulse returns to feeling balanced. It's really cool to watch as the patient can experience it in real time.
