Electrodermal Screening (Also known as EAV) evaluates the energetic health, nutritional state and toxicity of the client. The assessments are performed by measuring variations in skin characteristics at specific points on the skin, usually on the fingers and toes. Based on acupuncture, these points are connected energetically to the major organs and systems of the body, and from the readings obtained, the functioning of the various organs can then be assessed. Not only an excellent diagnostic tool, electro-dermal screening can be used for treatment as well.
