The Avatar instrument is based upon the principles of Electro-Dermal Screening (EDS) or Electro Acupuncture according to Voll (EAV). Dr Reinhold Voll being the inventor of this type of assessment which takes advantage of the electrical conductivity of the acupuncture system. He found that if he passed a very weak electrical current (the same as just holding an AA battery) through an acupuncture meridian there was firstly far less resistance to the electricity than if it wasn't through a meridian and secondly he could gauge the healthy of that meridian and therefore the associated organs healthy by the amount of electricity that made it through the meridian out the other hand.
The readings are as follows; 100 units of electricity are passed through the meridian through an acupoint on the hands or feet. If 50 units come out to the other hand, which is holding a copper "handmass" then that meridian is functioning well and healthy. If more is returned, say a reading of 75 then the organ is acute and inflamed and if it is lower than 50, say 30, the organ is chronic and functioning under par.
The full screen is 49 points covering all the major organs. Once the full screen is complete the priority point is calculated by the Avatar and this is the point that further testing is done from. The importance of this point is that it is the best point to access the health of the whole person off, according to Voll's years of experience. For example, the priority point may be the liver, indicating that the liver needs help, or will do shortly, however the patient, off this point may then test for a complete range of bowel remedies and no liver ones at all. This is called the "causal chain" and indicates that the liver requires the bowel remedies to help it, and as we know the bowel clears its toxins into the liver. In this scenario just cleansing the liver and not the bowel would not get to the cause of the problem as the bowel toxicity will just re-fill the liver. This is the advantage of having a highly accurate assessment device like the Avatar it can show the causal chain of events and enable me to track events back to get to the cause of the problem to give long term relief.
It is also possible, as mentioned, to test remedies and supplements. The effective range I use have been designed specifically for this type of testing. The are remedies for the different organs, drainage remedies to shift toxins and also ones for specific problems like candida, bacteria overgrowth, viral problem, mycoplasma patterns and many others. So in the example above if the liver point tested up for bowel remedies and one of those was the one to clear candida then we can assume that the liver is actually being affected by candida overgrowth in the gut!
Food allergy testing
Along the same lines as remedy testing it is possible to test for food intolerances or allergies. For example if the allergy acupoint is used and this reads at a 50, so it is well balanced, and then a food it tested and it throws this point out of balance to a 30 then it is indicated that there is a bad reaction to the food and it should be avoided.
On top of the 49 points of the basic screening it is possible to use all of the points on an acupuncture meridian to really focus and improve accuracy. For example when assessing foods for allergies I would "branch" up the allergy meridian and find the best point to test the allergies on. In the same way when testing hormones I would "branch" up the hormone meridian and find the best one to test off, i.e. adrenal, thyroid or ovary point among others.
