Electro Dermal Screening

The Basics of EDS and How It Can Benefit You

Electro Dermal Screening or EDS is a mainstay of holistic practitioners.

  It is a way to fine tune nutritional supplement, homeopathic, and natural health protocols with a great deal of precision. EDS was developed in Germany through the work of German physician Doctor Reinhold Voll almost 50 years ago. Thus it is also sometimes referred to as Electro Acupuncture Voll or EAV. EAV has not been embraced by American Pharmaceutical medicine because it is a fairly inexpensive modality and thus not very profitable, therefore most American have never heard about it. You may be one of these people who know little about it. But despite this neglect by the profit driven American medical system, Electro Dermal Screening has been quietly developing as highly effective modality. This has come about through the constant efforts of holistic practitioners using EDS to get better results from these modalities, as well as rapid advances in electronics, and the extreme competition between the dozen or so Electro Dermal Screening equipment manufacturers to build a better machine. But before discussing modern EDS advancements, let’s go back to the beginning.
Doctor Voll discovered that giving someone an oral dose of a homeopathic remedy or other natural product immediately changed electrical resistance quite dramatically at specific points on their skin. These were later named EAV points from Electro Acupuncture According to Voll. Dr Voll meticulously researched these points that were mostly on the ends of the fingers, and he also correlated many of these points with existing Chinese medicine acupuncture points. He went on to discover many additional points beyond Chinese medicine. Traditional Chinese Medicine practitioners had for 1000’s of years relied on clinical observation of how sticking needles into specific points affected health. But Voll was taking advantage of modern understanding of electron flow.

How did he discover where the points were?

Put simply, by placing a probe on the skin, he discovered that these points had drastically lower electrical resistance (meaning they conducted electricity much better than skin just ¼ inch away). While it still cannot be said with certainty, the hypothesis is that these points, many of which as stated were already known acupuncture needle points, were perhaps circuits of electron flow in the body. Now to explain all this a bit further, Voll discovered that if the flow of electricity in one of these points seemed to be altered, too much or too little, it often correlated with disease or dysfunction in the correlating organ system. He also discovered quite by accident that not just taking herbal, homeopathic, or other remedies, but also putting them directly onto a person’s body, changed the electrical activity at these points. In other words, he didn’t even have to give the patient a remedy orally. He could affect their measured electrical resistance just by holding a remedy on their body. Back in his day Voll ended up with 1000’s of test vials that could be tested one by one on each patient. It was truly a unique system he was creating. One does not attain what Voll did without a measure of obsessiveness, above average intelligence, and a bit of eccentricity. Although called a quack by mainstream American medicine, (quick definition of Quack in America: Anyone who threatens pharmaceutical dollars), the Government of Germany disagreed, awarding him the distinguished Federal Cross of Merit award in 1979 for his work.
It is a shame that everything that poses the slightest threat to medical profits in this country is summarily given the stamp of quackery. In other places many of these natural modalities are used right alongside medical lab testing, radiology, and conventional treatments. Integrative medicine that embraces both natural and medical methods seems to bring the best results to the suffering. Reinhold Voll was highly intelligent and discovered some amazing things in his field.

Fast forward to modern times

While Voll helped many sick people those decades ago, perhaps more importantly, he began a holistic method of testing that has endured, has been embraced by many innovative companies, and has emerged in modern times as an available, highly effective tool for anyone who seeks it out. There are over a dozen companies manufacturing the new generation of Electro Dermal Screening Devices. Earlier ones were the Acupath, Biotron, Computron, Dermatron, and DiagnoMeter, and IQS. At Natural Health Sciences of Arizona we use two modern cutting edge devices, the ASYRA from G-Tech, and the ZYTO from the ZYTO Corporation. They are faster, and more accurate than anything seen in the past. Both these machines are able to quickly test multiple EAV points and multiple frequencies in rapid fire succession, instead of the old painstaking method of placing one testing vial at a time into the person’s energy field while testing multiple points. They do this by outputting the frequency of the remedy or substance electronically.
As you, the client, sit in the office holding the 2 ASYRA electrodes, or with your hand on the ZYTO hand cradle, the devices output about 1 frequency every ½ second. This is plenty of time for your body to respond to that frequency and to create a change in the electrical flow at your EDS points. The devices measure these changes in all the EAV points simultaneously and have proprietary software for analyzing the data. This allows me as a traditional naturopath to look at the end results and make recommendations on what natural products and therapies will be most beneficial to support healing. The procedure is painless, noninvasive, and most people don’t even feel anything although some sense the very slight current that is being outputted by the devices.

The ZYTO and ASYRA Electro Dermal Screening machines

Two cutting edge tools for holistic health when properly used

I find that using both the ZYTO and the ASYRA provides the best result as these balance each other out well. They are both incredible machines. They actually do come out of the box with some ready made, cookie cutter protocols, but these admittedly do not have much value. The real benefits come when highly customized EDS scans are created. In fact it is unlikely that any two skilled natural practitioners use them exactly the same way, because in order to get the most benefit from the ASYRA and ZYTO one must first create these highly customized scans from the tremendous amount of base data in each unit. These customized scans require knowledge and training to create. In addition each device, and then one must have the knowledge to interpret each person’s individual scan results after the scan is done.   natural-health-sciences-arizona-zyto-scan-how
Sadly, people often come to see me who have struggled for years with chronic health challenges who have a “been there, done that” point of view due to disappointments with just about everything including Electro Dermal Screening. They often report that they have already “done” the ASYRA or “done” the ZYTO and perhaps got limited benefits or none at all.  Otherwise why would they be setting in my office still trying to get well? After their evaluation they realize they had not previously seen the full potential of this natural modality. That in fact they had never gotten the benefit of a thorough EDS scan specific to their health challenges, although working with someone who claimed to know what they were doing. Let’s face it, there are good and bad in all professions. Holistic practitioners are similar to medical doctors in the sense that realistically there are the good, the bad, and the awful. As far as the work that I do with the ASYRA and ZYTO EDS equipment, the results speak for themselves. The reports you may read on our website are only a fraction of the people who have reported benefits. I love the work I do, and do have the background and training to do this work, but of course do not claim to have all the answers. In health oftentimes it seems that you don’t have to address everything, you just have to address enough things to unblock healing and the body does the rest. Many of our clients are extremely well read and knowledgeable. People take note when they have an EDS scan that highly correlates with their symptoms and illness, and thereafter begin taking natural remedies that are genuinely improving their sense of well being. It is a pleasure to see people react positively as they realize that they are getting a thorough and comprehensive scan that makes sense to them, and to return for follow-up appointments excited with the results they are seeing.

How we use both the ASYRA and ZYTO for your EDS evaluation

Your ASYRA scan

Although it is evolving from year to year, our current procedure at NHS of Arizona is to use the ASYRA EDS device from G-Tech to scan you for the energetic resonance of such things as toxin accumulation, including heavy metals, chemicals, and bio-toxins as well as various homeopathic and other remedies to assist your body to mobilize and excrete these. This is done with the use of homeopathic drainage and detoxification support remedies, as well as specific and individualized nosodes of the toxins. A Nosode is a homeopathic remedy made from the disease causing substance. In the case of toxins, a nosode is a homeopathic remedy made from the toxin, thus following the original homeopathic principle of like-cures-like. They contain the energetic resonance of the toxin that is burdening down your body, not the actual toxin. The ASYRA both energetically scans for these toxins and allows the practitioner to also imprint the needed homeopathic remedies from the test plate.
Some of these methods are from the protocols created by Dr. Lee Cowden M.D. They are extremely thorough. The mercury nosode alone contains the energetic resonance of over 30 types of organic mercury and inorganic mercury salts. The use of a toxin nosode is a standard practice in homeopathy to help the body eliminate the toxin. The individual results from your scan will be used to make homeopathic drops and vials for the Laser Energetic Detoxification protocol. The ASYRA is also used to energetically identify issues such as hormonal, neurotransmitter, structural problems, miasms (or familial tendency toward disease), and critical issues such as focal organ toxicity, parasympathetic and sympathetic nervous system switching (likely due to adrenal exhaustion), dehydration and mineral deficiency, and many other things. This is, as stated an energetic analysis of said issues, but very useful in creating non-toxic, natural homeopathic, supplement, and cleansing protocols to address these things. The results people report from doing an EDS scan for toxins and then following up with a Laser Energetic Detox session show this to be one of our most effective natural therapies. As a client sitting for an appointment, you could expect that the ASYRA would also be used to look for the energetic resonance of food and phenolic allergies, inhalant allergies (dust, mold, pollens, fabrics, etc). We would also test any one of a variety of categories of infection such as bacteria, Lyme disease and co-infections, protozoan or larger parasites, yeast and fungi, and viruses. Once all the ASYRA scans are done highly individualized homeopathic imprints will be made for you. Because of the complexities of the different scans that are done, it is virtually impossible for two people to ever get the exact same homeopathic drops. What you receive is precisely for you.

Your ZYTO scan

  If you come in for a full evaluation the ZYTO would be used as the primary tool for determining which nutritional supplement protocol would support your health best. Currently, (Spring 2014) I use it in the following way: With your hand on the hand cradle it first measures your baseline energy or impedance. The 2nd step once the baseline is doing an energetic baseline organ stress level. This scan also looks for stressors in the Chinese meridians, dental meridians, and for other potential things blocking energy. For the 3rd step, once the ZYTO energetically determines what is out of balance, I would then scan you for anywhere from 500 to 2500 different therapeutic nutritional supplements, homeopathics, and all natural products of every kind.
* This 3rd step in the ZYTO nutritional scan assigns the many products scanned a numerical value as to how your body responded to them energetically-good or bad. Some products that you may have thought would be great for you may have in actuality blown you out from an energetic standpoint. This is the folly of taking everything you hear about on TV or at the health food store. Some things may just flat out not agree with you, regardless of how amazing (or perhaps exaggerated) the claims are. You are unique! Your health needs are unique. This 3rd step in the process narrows the large amount of supplements tested down to just the ones that balanced your body’s energy system, thereby eliminating about ¾ of the products as non-beneficial.
The 4th step in this process is going through only the list of all the supplements that balanced your body’s energy, and further narrowing them down to ones that are clinically relevant to your health. Clinically relevant that is from a natural health standpoint. Using natural products that are designed to support healing of the specific health challenges one is tackling. This is an important area where working with a knowledgeable holistic practitioner comes in. There are many, many nutritional, herbal, and other supplements hitting the market daily. An EDS device cannot tell you which ones are best for a person’s unique health issues. This takes training and knowledge.
Once the supplements needed for your specific health challenges are chosen, the 5th and final scan is done. In this scan these final selected products are then tested against the original stressors that showed up on your baseline organ function test that was done earlier to see which of these products balance these original organ stress issues. Thus a thorough and final narrowing down of all potential therapeutic choice is done. Usually the end result is about 3 to 8 products. I sometimes further reduce these using clinical knowledge of how these natural products would interact the other things we are doing, whether or not specific results are being duplicated, or is there any negative interaction between products (it is also very important to know interactions with meds one is taking). Again, this is something that the EDS device doesn’t do. It is like a Yes/No device. It assists with making decisions by saying Yes, this products seems to make this person’s energy happy (balance). Or no, this product seems to make this person’s energy unhappy (stress).

What to expect when you come in

With a new person who has scheduled an evaluation that allows enough needed time, all the above mentioned things will be done as well as various others things not mentioned here. Regardless of the scans run and the data created it is our goal to create manageable natural health protocols; ones that can be completed over a two month period, even by individuals who work or have other responsibilities. No these protocols are not always simple, but human health and chronic illness is not simple. Illnesses are complex and multifactoral. You must unload the body in a methodical and logical fashion and our goal at NHS is to create natural health protocols that do this. We get consistently good feedback from the individuals who follow them; people who are inconsistent and forget to do their protocol, not so much (good feedback). The good news is many of those who visit our office fighting difficult health challenges have already tried easy. They are now looking for something that works. Of course people in relatively good health seek NHS of AZ services as well. They just want to do prevention and use this modality as part of a healthy lifestyle. These folks do well with much simpler natural protocols. It is the nature of things. If you are not sick, you don’t have to fight very hard to gain optimal health, if you are ill, it is harder. But people are wise in valuing health although not having had the experience of having lost it. If you have never experienced the uniquely powerful benefits of EDS, feel free to schedule your 1st appointment today. People with little or no training who buy an EDS device and hang out a shingle a week later do not do justice to the benefits of this modality. Some unscrupulous individuals with little knowledge of human health and only rudimentary knowledge of natural medicine are using them. It takes a background of years of holistic training and schooling, and specific training on the EDS devices being used for any real benefit. Beware of working with someone who has no training. Just do your homework. Someone with no training and experience won’t tell you they have no training and experience. *Please note that this change in a person’s electrical resistanceHerbal Essence Dropper is not a diagnosis of a specific allergy or infection. The principle is that these EDS devices output the energetic frequency or resonance of a specific allergen or infection. If one gets a hit, or a negative change in energy, this can indicate energetically that the body recognizes this as a harmful microbe of substance. These results are then used to create homeopathic remedies to support healing. One explanation of how a homeopathic nosode of an infection can stimulate healing of a chronic infection is that by putting a lot of the energy or resonance of a pathogenic infection into the body, you give the body a wake-up call and stimulate the immune system to work more aggressively to get rid of it. While these are not a precise diagnosis or treatment of an infection, neither the scan nor the homeopathic drops cause harm so why not use them? These methods have been used effectively for infection for more than two centuries. Dr. Samuel Hahnemann, the originator of Homeopathy, even used this method to drastically reduce deaths from the Cholera that French troops were suffering after Napoleon called him to the front line and requested his help. He took some of the Cholera parasites from the French soldiers dysentery induced diarrhea and used it to make a homeopathic Cholera nosode using his now well known dilute and succuss methods.  From Hahnemann’s time homeopathy spread throughout the Western world as a viable alternative to the purging, bleeding, and use of toxic metal based medicines that the heroic medicine doctors of his day were using. But early in the 20th century Homeopathy came under attack by the American medical establishment and was suppressed thereafter. This had nothing to do with its efficacy but was done for purely economic motives. Thus, while  homeopathy is used extensively in other countries (the Queen of England has a homeopathic doctor), it is only recently making a comeback in the U.S. due in part to the Internet and the inability of powerful economic and corporate interests to control information here in the U.S. as has been the case in the past. While homeopathic nosodes for infection have shown clinical results, including double blind placebo controlled studies done in other countries, they are not a substitute for proper medications or other interventions for dangerous or life threatening infections. *Natural Health Sciences of Arizona maintains accounts with a variety of nutritional supplement companies that provide products primarily to holistic health care practitioners. It is important to use companies that use pharmaceutical grade nutrients and strict product quality control when it comes to contaminates. Currently the companies that we work with provide over 15,000 products that we choose from in creating supplement protocols. When you come in for a scan, I will scan you for products from whatever specific combination of supplement companies best suits your needs.
