Electrodermal Response

What is ElectroDermal Response?

Electrodermal response measures the resistance to the flow of electrons through the body. Since many factors cause the body's resistance to change, electrodermal response identifies these factors.

What am I tested for?

The functionality of the subject's tissues, muscles and organs, plus the presence of bacteria, viruses, mold, metals, chemicals, radiation, horomonal issues, gut acidity imbalance, vitamin/mineral deficiencies and much more. Homeopathic liquids, supplements and medications can also be tested with the subject, to assess what effect they may have.

What happens during an appointment?

The subject holds the brass electrode (the negative lead and source of current) in their non-dominant hand. Simultaneously, the provider gently touches acupoints of the subject's dominant hand with the black electrode. Electrodermal response data is captured on a screen in real time.

Is it FDA-approved?

The Discovery System is recognized by the FDA as an investigational device. Computerized biofeedback analysis is endorsed by many doctors here in the US, including Dr. C. Shang of Harvard University who has urged the medical community to make full use of this technology in order to gain knowledge of the body’s functions.

Why should I get tested?

Testing can discover the following issues, because it conducts a dynamic assessment of the body's tissues, organs and systems:

  • Chronic infections (i.e. Borrelia burgdorferi, a.k.a. Lyme Disease, Epstein-Barr, influenza, chicken pox, etc.)
  • Gut acidity imbalance
  • Circulation issues
  • Mineral or vitamin deficiencies
  • Chemical or radiation poisoning

These issues are likely to manifest into the following symptoms:

  • Allergies
  • Insomnia

  • Brain fog (i.e. confusion, forgetfulness or lack of focus)

  • Fatigue

  • Headaches

  • Joint pain

  • Muscle pain

  • Fever/chills

  • Mood swings

  • Indigestion (bloating, constipation, diarrhea)

What technology do you use for testing?

The Discovery system, a state-of-the-art testing device with Windows software that translates the results instantly. It measures electrical currents in the body, like an Electrocardiogram (ECG or EKG) machine measures the electrical activity of the heart.

In this type of testing, electrical resistance measurements are taken by the practitioner touching the positive probe to the point while the subject holds the negative probe in the opposite hand. There is no feeling of electrical shock due to the extremely low voltage involved. The ideal reading would be at 50 on the scale. Higher readings suggest inflammation or infection, while lower reading suggest degeneration. Readings that drop after a few seconds suggests chronic conditions.  

We also use hundreds of different test vials electronically put into the circuit to measure health factors like nutrient deficiencies, allergic sensitivities, and toxicities. The test vials are normally homeopathic dilutions of substances whose resonance corresponds with a particular health problem. Dilutions of vitamins and minerals are used in the D30 potency to measure deficiencies for example, while D6 potencies of toxins are used to measure toxicities. Starting from that perfect “baseline” reading, different test vials are introduced into the circuit to see which ones throw off that baseline reading. In this way nutrient deficiencies and allergic sensitivities are determined.

For example, if the adrenal is weakening the pancreas which in turn is weakening the thyroid, I would put the adrenal test vial in the test circuit and see it produce a high reading from the baseline indicating its weakness. Then I would add different adrenal glandulars, DHEA hormone, or maybe licorice root herb to see which ones will correct that weak reading on the instrument. Then I know which supplements are right for balancing that client’s body. The information possibilities with this type of electrodermal testing are almost endless.

Modern physics show that the fundamental basis of all things is energy. So therefore, measuring your body's energy takes away all of the guesswork.

Is this technology medically researched and published?

Yes, the Cleveland Clinic classifies electrodermal response as a form of biofeedback therapy. It's published work can be viewed at PubMed and the abstract states, "Biofeedback involves the monitoring and use of physiologic information to teach patients to modify specific physiologic functions. Common modalities for biofeedback include surface electromyography, respiration rate and depth, skin surface temperature, cardiovascular reactivity, and electrodermal response. Clinical biofeedback therapy broadly involves either the direct feedback learning model or the therapeutic/stress-management/biofeedback model, which emphasizes the need to understand each patient as an individual. Biofeedback interventions have been deemed efficacious or probably efficacious in treating a number of medical disorders, and are increasingly embraced by the public as well as by health care providers and payors."

WebMD further details the processes of biofeedback therapy.

Thirdly, a study was performed at the U.C.L.A. School of Medicine to determine if the E.A.V. lung test readings would be worse on confirmed lung cancer patients as compared to controls.  A high degree of correlation was noted with 26 of the 30 E.A.V. examinations matching the chest X-ray results in a blind test.  [“Evoked Electrical Conductivity on the Lung Acupuncture Points in Healthy Individual And Confirmed Lung Cancer Patients,” American Journal of Acupuncture, Vol. 13, No.  3, July-Sept 1985.]

Lastly, another fascinating study sought to measure the effectiveness of E.A.V. testing in measuring food allergy.  It compared the electrodermal testing with five conventional medicine methods of food allergy testing—skin, RAST, IgE, history, and food challenge.  Results showed a high degree of correlation, particularly with food challenge, probably the most accurate of the conventional methods.  [“A Food Allergy Study Utilizing the EAV Acupuncture Technique,” American Journal of Acupuncture, Vol. 12, No. 2, April-June 1984.]

What is the history of electrodermal response?

A German physician, Reinhold Voll, M.D., developed the first electrodermal testing instrument in 1953 after having cured himself of terminal bladder cancer with acupuncture. In his struggle to integrate the very different system of acupuncture with his knowledge as a western, anatomically trained medical doctor, he found that there were electrical resistance differences that could be measured with a modified galvanometer on the surface of the skin (no needles!) on these reputed acupuncture points.

However, the idea that the body’s fundamental nature was electromagnetic can be traced back to 1935 when Dr. Harold Saxton Burr, Professor of Anatomy at Yale University School of Medicine published his Electrodynamic Theory of Life. Dr. Burr designed a voltmeter to measure energy fields surrounding every living system, which he labeled “L-Fields.”  He theorized that L-Fields were pre-physical fields which organize the physical body as it continually goes through the processes of growth and metabolic change. In other words he felt there is a deeper level of life beneath the physical and chemical levels we normally measure—an electrical level that is ultimately responsible for producing our physical and chemical bodies.

G.W. Crile, M.D. was a surgeon and the founder of the famous Cleveland Clinic. He wrote a work entitled, The Phenomenon of Life—A Radio-Electric Interpretation. Addressing the American College of Surgeons in 1933 he predicted that a “radio-diagnostician” would detect the presence of disease before it becomes outwardly apparent. He stated that man is a radio-electric mechanism, emphasizing that when life ends, radiation ends:

It is clear that radiation produces electric current which operates adaptively the organism as a whole, producing memory, reason, imagination, emotion, the special senses, secretions, muscular action, the response to infection, normal growth, and the growth of benign tumors and cancers, all of which are governed adaptively by the electrical charges that are generated by the short wave or ionizing radiation in protoplasm. 

That is pretty incredible—here’s one of the giants of conventional medicine in the 20th century stating the basic foundation for the electrodermal testing done today.


Over 3000 years ago the Chinese recognized there was an energy flow in the body that could be measured and manipulated to achieve healing.  The idea of energy flow along so-called “meridians” has been scoffed at by many conventional doctors, though acupuncture has gained pretty wide acceptance within conventional medicine, simply because it can be observed to work (people having open heart surgery are known to have only acupuncture anesthesia).

Research done in Paris since the mid-1980’s has proven the existence of the acupuncture meridians, as a distinct system from the nervous, lymphatic or vascular systems. Jean Claude Darras, M.D. and Paul DeVernejoul, M.D., by injecting a radioactive tracer at acupuncture sites and photographing the movement, found the acupuncture meridians different from these other known systems.
