Subject: Allergy Desensitization
Meridian stress assessment seems to be at least as reliable, and probably more reliable, than other forms of allergy testing available. It is much safer than skin or challenge testing, since exposure to an allergenic substance is minimal. It is also much more pleasant for the patient than skin testing, since this form of testing is relatively painless. There are also no unpleasant adverse reactions, which may last for many days with skin or challenge testing. Meridian assessment is usually much less expensive and helps to eliminate trial and error treatment dosages. Dennis W. Remington, M.D. "A History of Meridian Stress Assessment"
Subject: Electrical Skin Conductance in diagnosis
In clinical practice, EDS instruments are useful as diagnostic supplements to blood tests, radiographic imaging, and case histories historically and currently, EDS instruments characterize differences between inflammatory and degenerative conditions. The integration of reliable and valid bioelectric medical instruments into the clinical setting augments the ability to rapidly evaluate tissues which are difficult or impossible to asses by conventional test procedures.

Subject: The Effects of Gender or Age on Point Readings
This study was done on healthy subjects; 348 males and 135 females were studied for the bioelectric activities of the body using the principles of electro-acupuncture according to Voll. In spite of some variance among testers there were no gender and age effects for all specific points studied. These findings should be important for consideration in using these measurements for medical diagnosis. Studies of Bioenergy in Healthy Subjects by Julia J. Tsuei, M.D., Chieh Chung, M.D., Frederick M.K. Lam, M.D., and Ming-pi Mi, Ph.D. American Journal of Acupuncture, Vol. 16, No. 2, April-June 1988
Subject: Bioelectric Homeostasis
A homeostat is a hierarchical regulating structure, which in the process of its action maintains dynamic stability of some physiological parameter of the living organism. Bioelectrical homeostasis forms a first level homeostat that is united into a second level homeostat by the autonomic nervous system. The first level homeostat, bioelectrical, influences control through the autonomic nervous system which is responsible for the equilibrium in the internal systems of the body. Where meridians are regulator-executers that provide information to glands and organs that are regulator-controllers through the autonomic nervous system.

Tiller, Department of Materials Science and Engineering Stanford University, Stanford, CA 94305
Subject: Electromagnetic Frequencies (Signatures of Items)
The most straightforward expressions of useful electrical quantities are as complex numbers in frequency domain. This article goes on to explain how the body responds to these frequencies and how we can measure that response through specific locations on the skin. Dialectric Response in Human Skin by William A. Tiller, Department of Materials Science and Engineering Stanford University, Stanford, CA 94305
Subject: Bioelectromagnetics versus Biochemistry
The National Institute of Health states that "bioelectrmagnetics essentially underlies biochemistry, in that chemical reactions of biological importance are mediated by the electromagnetic force." Bioenergetic Medicine offers the possibility of more economical and more effective diagnosis and noninvasive therapies for medical problems, including those considered intractable or recalcitrant to conventional treatments.

Subject: Radioactive Isotope Imaging of Meridians
The work was conducted on over 250 healthy control subjects and on 80 patients with renal pathology. The work was conducted on patients form the Department of Urology and from the Acupuncture Department of Biophysics and Nuclear Medicine from the Necker Hospital in Paris with each experiment repeated several times. Morphological studies found those tracer migrations from acupoints in both healthy and sick patients followed the same identical pathways with those described as "meridians" in Chinese traditional medicine. The study also found that the rate of flow through the meridians was altered by chronic or acute pathology.

Subject: Snapshots in Time
Disease processes disrupt the body's normally balanced mechanisms. Current chemical analysis only captures "snapshots" that measure a brief time frame, creating the appearance of a static state where none exists. By measuring electrical resistance over time, EDS devices provide clinicians with a dynamic profile of these normal or distorted oscillatory patterns. The evolving field of bioelectric medicine holds great promise for the early diagnosis of significant disease states and for earlier and more effective treatments.

Subject: Meridians and Coronary Heart Disease
This research found that there was a relation to diagnosed heart disease and the electrical resistance of tissues connected through a meridian pathway. They showed these electrical resistance values were specific and distinct for each type of disorder as well as chronic and acute interrelations. Characteristics of Reactive Electropermeable Points on the Auricles of Coronary Heart Disease Patients; Clinical Cardiology (16, 415-419, 1993) by Keijiro Daku, M.D., Ph.D.; Yoshito Mukaino, M.D., Ph.D; Hong Ying, M.D.; Kikuo Arakawa, M.D. Ph.D. (Department of Internal Medicine, Fukuoka University School of Medicine, Fukuoka City, Japan)
Subject: Medicine Testing and Physiological Response
EAV has shown that each acupuncture point bears a direct relationship to a specific anatomical structure or physiological function in the body. A serendipitous discovery showed that when medicine, if correctly chosen, will change the reading values to a more normal level. The scientific validity of EAV and medicine testing has been firmly established over the past quarter century and a number of laboratory experiments are outlined to substantiate and corroborate this exciting advance in medicine.

Subject: Diabetes Mellitus
This study demonstrated the effectiveness of medicine testing as a beneficial adjunct to the physician in determining the proper dosages of medicines prior to dispensing to the patient. It also showed that abnormally functioning organs, as indicated by testing the disease related acupuncture points, can be balanced by corresponding properly dosed allopathic medicines or homeopathic remedies and nosodes.

Subject: The Process of Healing
Injury to tissues represents a source of release of energy, leading to structural modifications in tissue. Artificial activation can even lead to beneficial effects in disease. This energy gives rise to a physiochemical potential difference in relation to surrounding non-injured tissue. This book goes on to explain the relationship between meridians, tissues, and how they are affected by something as small as one ionic charge. Biologically Closed Electrical Circuits by Bjorn E. W. Nordenstrom, M.D.; Nordic Medical Publications
Subject: Pictures of GSR or Acupuncture Points
Galvanic Skin Response clearly demonstrates the presence of an organized system of highly electroconductive points on the human skin. The techniques described in this article allow photography of these points and how they relate to the autonomic nerve reflexes. The photographed points form distinct organized patterns on the skin which closely correspond to the points noted on oriental acupuncture charts.
