Avatar for EDS Testing

There are basically two types of testing methods to determine which supplements/formulas will work best for your client: Muscle Testing or Kinesiology (many variations and names) and EAV/EDS/Biofeedback (many variations and names).

Muscle Testing is a valuable tool if you are patient and practice. Practice isn’t about doing it right or wrong – it is about being able to feel the difference in pressure on a variety of people. Like EAV/EDS, testing items should follow the client’s needs. This is a confusing sentence but refers to understanding functional anatomy.

Example: You have reviewed the symptom form and asked the additional questions you need to determine what may be the primary issues and have formed some ideas on what herbs/formulas/supplements may be needed. All supplements and food must be broken down and absorbed within the small intestine so you should start by first checking for excess bacteria/fungi/parasites, and a need for probiotics. Next is the liver which requires several nutrients to function correctly (zinc, vitamins B, C, A, D, E, K, sulfur, iron and more) so you test either formulas or individual items to determine the liver’s needs. With the person holding anything that the bowels and liver needed, add other items one at a time to find a yes or no response. This is a very simplified example!

EAV/EDS Testing is expensive to initially purchase but clients love being able to see what is going on and they tend to have more confidence with its use compared to muscle testing. This of course leads to more clients and client retention so the machine pays for itself. I have had years of experience with EDS testing and exposure to many systems and companies. Why didn’t I expose students to this wonderful equipment right away? Basically I didn’t want you to think it was a “must have” to work successfully with clients. Why now? Students have been asking about what they can do besides muscle testing and/or observation and logic/brain work.

What company can I recommend with complete confidence? Veradyne

Robert Eanes, the owner of the Veradyne Corporation is brilliant and his team has created units that are mid-range in price while still offering everything included in higher-priced units. They are also very portable and easy to learn how to use. Unlike some companies, they stand behind the software and even offer online beginning training (how to use the machine/do hand and toe points) as part of the package.

Pricing (as of 4/01/2022) –  Financing is available for qualified buyers.

  • Avatar SC-5: $12,000.00
  • WF-3000: $3,450.00
  • Complete Avatar System (SC-5 & WF-3000): $14,500.00

Genesis students/graduates will receive $500 off the units but the busy owner doesn’t want to spend hours on the phone trying to tell you about EDS. His main business is engineering – he keeps the Avatar System available because he knows it helps naturopaths help the public.

I don’t want to cover the basics either! So… Please read the linked articles and view the linked videos before contacting me about purchasing the Avatar system. I will forward your request and contact information to Bob and he will contact you to discuss payment, financing, and any general questions.  If you use this form or tell them you are a Genesis student or graduate you will get $500.00 off the unit. This is a good amount to save for reading a few articles to answer most of your questions! 

There is an article about EDS below this form!


EAV/ElectroDermal Screening

Electrodermal screening uses electronic devices to measure the electrical resistance at numerous points on the body. This technology is not an instrument used to diagnose disease. It does however measure the electrical current moving through the acupuncture meridians and as such gives information about the bioenergetics of the body. It is an instrument of physics, not chemistry.

In the 1950’s, Dr. Reinold Voll, a German doctor, observed that traditional acupuncture points had a lower electrical resistance than other skin points. He developed a device to measure the skin’s resistance at these points and found that each point had a standard measurement for all healthy people. He concluded that increases from this normal reading meant there was tissue inflammation associated with that point. Decreases from the normal reading indicated there was fatigue or tissue degeneration associated with that point.

The methods and technologies developed by Dr. Voll became known as “Electro-acupuncture According to Voll” or EAV. This technology is also known as electrodermal screening or EDS. The acupuncture points that are measured are usually on the hands and feet. Specific points known as control measurement points are used to indicate the general health of an organ or tissue. There are currently over two thousand points that have been discovered.

Dr. Voll made an interesting discovery when evaluating a fellow doctor who had a history of prostate problems. Dr. Voll measured the doctor’s “prostate point” and found it lower than the expected normal reading. Later that day, he measured the point again and found it to be in the normal range. At the second evaluation, the doctor had a natural remedy (homeopathic Echinacea) in his pocket. Dr. Voll discovered that abnormal readings could be corrected when a “healing medicine” was held by the person (or later placing it on a test plate that was in circuit with the patient and the instrument) he was measuring. This allowed Dr. Voll not only to find what organs were energetically unhealthy, but also what natural remedy would correct the problem, eg. homeopathic, botanical, nutritional, etc.

Various theories exist about how these machines work and what they measure. Some claim that the energy testing devices measure the amount of the qi or “life energy” that flows through the Chinese acupuncture channels. Others feel that the devices measure the amount of stress on each channel. An increase in stress will reduce the amount of electricity flowing through the channel. A natural medicine that helps resolve the stress will restore the normal flow of electricity and return the measurement to normal. Regardless, it is a fascinating phenomenon that has since become an increasingly reliable indicator in thousands of clinics worldwide.

Electrodermal screening can be very helpful with many health problems. A skilled EAV/EDS technician is able to detect the energetic signature of toxins, allergies, emotional patterns, organ “weakness”, etc., in the body. EDS can also screen potential natural remedies to determine which will help restore the body’s balance.

Electrodermal screening and energy medicine may be done by medical doctors, osteopaths, naturopaths, acupuncturists, chiropractors, dentists, etc. The accuracy of the screening is not 100% objective and is dependent upon the skill and experience of the practitioner. Current EDS instruments vary from simple machines to fully computerized devices.
