Electro-Dermal Screening is a type of biofeedback testing developed by Dr. Reinhold Voll in Germany in the 1940’s and 50’s to measure meridian energy flow in the human body. By measuring the energy of a meridian, Dr. Voll found that he could discover the energy state of the corresponding organ or system.


In his clinical experience he not only found that he could measure an electrical current flowing in the body independent of the central nervous system, but also that when he introduced a homeopathic signal into the biofield of a person or in the EAV device circuit, he noticed that it would change the EAV (electro-acupuncture according to Voll) response, which allowed him and his patient to see how a specific homeopathic remedy would affect that organ or system, and subsequently the body as a whole.



A meridian is an energy pathway that runs along under the skin between an organ or system and an acupuncture point. Acupuncture points are the energy pools that are at the end of the meridians and also at specific points along the meridian. Each meridian has a specific pathway that it follows. The Chinese found that there are 12 major energy channels flowing in the body. By analyzing the intricate relationships of the various channels, a wealth of information may be obtained. From this perspective, one is able to look at the whole picture of health and find any potential imbalances that might one day create functional distress, simply by assessing each of the energy channels, which make up the body's invisible information network; linking all of the organs and systems together. The Chinese model of medicine explains that the twelve main meridians are mirrored on both sides of the body, resulting in 12 distinct paired pathways. Each pair correlates with some organ, system, or process in the physical body for which the meridian is named. If there is an imbalance between the pairs it can now be easily identified with EAV Testing.

As the field and influence of Voll’s EAV grew, the Japanese and Americans developed similar devices and computerized EAV by the end of 1980. Dr. Bodo Kohler of Germany states that recent research emphasizes the true link between the meridian system and current biophysical knowledge. In his paper entitled Biophysical Information Therapy (BIT): The Evolution of Subtle Energy Medicine, he says, "The information flow in the human in all likelihood identical with the meridian system," supporting Voll's findings.

It is apparent that the extensive research of Dr. Reinhard Voll over fifty years ago has provided a bridge between ancient Eastern wisdom and the findings of modern biophysicists, creating a new paradigm for health and wellness assessment. The basic difference between EAV and other forms of conventional biofeedback is that EAV typically is not used for voluntary stress management. Rather, it collects information from the body without the participant's manipulation of the data. In this respect, it is often referred to as non-cognitive biofeedback.

EDS Research

Although EDS (Electro-Dermal Screening) is used in Europe for diagnosis and is considered part of conventional medicine, in the US it is still considered an investigational device. The FDA is currently exploring the use of EDS as a non-invasive diagnostic instrument. An increasing collection of knowledge is available through EDS testing about the nature of what is happening in the body.  EDS can be used to assist in the understanding of health challenges caused by bacterium, viruses, parasites, chemical toxins, nutritional deficiencies, heavy metal toxicity, mold/fungus, allergies and organ “weakness” in the body.

Create Inner Balance in Mind & Body

In order to maintain health, an adequate, unhindered and balanced flow of energy must be evenly present throughout the body. Any imbalance in the energy flow can eventually lead to illness.

It has been shown that stress hinders the flow of energy through the meridian system, affecting the tissues and creating imbalances within the body.  A healthy life energy is not static - it depends as much on free movement as it does on the energy itself. Likewise, balance is not static. Balance implies equal and opposite forces working in harmony to regulate each other. In dynamic living systems these forces are in a perpetual state of flux, constantly moving and synchronizing together. If an unbalanced state occurs, it is due to one force dominating another, either because the greater energy has become excessive, or because the lesser energy has become stagnant.

What can cause these imbalances of energy force?  Primarily, stress. Under stress, body systems weaken and stress can downgrade all metabolic cellular functions including metabolic and detox pathways, hormone systems, neurological systems and body organ systems can all become negatively affected. There are many types of stress: emotional, pathogenic, toxic exposures, deficiencies (which create stress on the body to compensate for these in order to maintain homeostasis). Electro-Dermal Screening is a great tool for uncovering these imbalances and stressors, as well as determining the best course for re-balancing the body.
