The Interference Field
Any part of the body that has been traumatized or ill can become an interference field [1,5,19,4,18]. An interference field can cause disturbance anywhere in the body no matter where it is located. Every being is a potential carrier of one or several interference fields: 30% to 45% of all illness or pain is caused by an interference field . The overall success rate of treating any given illness or pain with neural therapy by a good neural therapist lies at approximately 65% (treatment of interference fields plus the other Neural Therapy techniques) .
An interference field can on its own cause illness or pain. More commonly, the interference field is a link in a chain of interference fields, and for successful treatment all involved interference fields must be found and treated. For example, a woman with pelvic pain improves for 2 days after a Frankenhauser ganglion block [1,10,24,25], then her pain returns. On the next visit, both the thyroid [1,10,24,25] and the Frankenhauser ganglion are injected. The result is now lasting.
General illness such as malnutrition , emotional stress, geopathic influences, eating incompatible foods, and other conditions can convert inactive interference fields into active interference fields. For successful treatment, both conditions need to be recognized and treated. If only one condition is treated, there will be only partial or temporary improvement.
The most frequently overlooked interference fields are (a) the teeth and (b) the intestines.
In Germany, the term "frozen regulation" is used frequently. This indicates a condition in a patient who cannot respond to Neural Therapy, acupuncture, homeopathy, and other gentle interventions. The condition is frequently caused by certain medications. The most common are the following: steroids, antibiotics, antihistamines, and psycho-pharmaceuticals .
Some indicators that an interference field is causing the present illness are:
- The illness is not responding to other therapies.
- Another type of treatment has made the patient unexpectedly worse. For example, the patient received an injection into the knee joint for chronic knee pain. His knee became much worse. In Neural Therapy this is called reaction phenomenon and indicates that an interference field located elsewhere is causing the knee pain.
- All symptoms are located only on one side of the For example, a patient has right-sided tinnitus, right-sided shoulder-arm pain and right-sided knee pain.
- Summation of interference fields: after an appendectomy the patient develops rheumatoid arthritis. The appendectomy scar adds one more link to the chain of interference fields which is now strong enough to cause the rheumatoid arthritis. At this point, all involved interference fields need to be found and treated.
How to Find the Relevant Interference Field
History. What was the last illness, trauma, surgery, dental work before the patient developed his present illness?
Systematic Search. This is easiest with a pain patient. Before beginning treatment, a careful range of motion evaluation  (for example, shoulder abduction before treatment only 30°), and a careful re-examination after each Neural Therapy injection (for example, after appendectomy scar injection 70°) should be undertaken.
During the first session all scars are treated [1,3,19, 25,28,22,4]. After each scar injection the painful joint or illness state is reassessed. During the second session the pelvis is treated [1,10,26,25,28,19]. During the third session the chest is treated [1,10,28].
Empirical Approach. Certain empirical relationships between the interference field and the illness are more common. Examples include : tonsils–knee joint; abdominal scars–large joints and low back; leg scars–sciatica; tonsils and teeth–migraine; prostate, stomach, and sinuses–neck; gallbladder scar–shoulder; pelvic scars-PMS, depression, arthritis.
It is valuable to understand the energetic relationships that are taught in different "healing systems." A scar that crosses an acupuncture meridian is more likely to cause disturbance on the structures that are related to this meridian than elsewhere. For example, a gallbladder scar is often responsible for chronic hip pain. It is important to understand the tooth–organ relationships [18,19,29]. For example, the four front teeth in the upper and lower jaw are related to the urogenital system and are frequently responsible for pelvic pain, chronic kidney disease, and even malignancy in the pelvic organs. Another example is the wisdom tooth which often is responsible for chronic heart problems. Other valuable systems that I have found are the Chapman reflexes and simply the dermatomal relationships that are known in neurology.
Muscle Testing (Applied Kinesiology). These tests will be revealing of such relationships as well .
Hidden Messages from the Patient. This is one of the tools that distinguishes a practitioner from an excellent practitioner. While taking the history, the patient may—in between the very important events in his past—mention "some silly little thing" that would usually go by unnoticed. This "silly little thing" may be the very key to the patient's getting well. While taking the interview, the physician may also notice a scar on the patient's hand or ear and be drawn to it in some way. By listening to those inner messages and initiating treatment in a way that responds to these messages, the physician will notice that he will be guided to more and more successful treatment.
The Guiding Phenomena. After the first treatment, the patient is instructed to write on a note pad for 48 h all the major and the smallest changes that occur in his body. The body is basically asked to respond to the first treatment in a way that will guide the practitioner to the correct next intervention. The following phenomena are common and have to be kept in mind at all times:
- Indications that the correct interference field has been treated.
- Huneke phenomenon [1,3,4,11,22,19]. There is complete relief of all symptoms for 20 h or longer. If the nerve of a tooth had been injected, the result has to last for 8 h or longer.
- "Knallkopf ' . In translation this term means "exploding head." This occurs more commonly in women and is a feeling of exploding heat in the head which lasts for several minutes.
- The patient has a "bliss attack" or just simply feels extremely good after the injection.
- Emotional release . For example, after a pelvic injection a female patient has a brief memory of a sexual abuse that happened in her childhood. She feels anger, rage, and tears, which usually are successfully released within a few minutes. Sometimes a grieving process follows that can last up to several The end result most commonly is, however, that her chronic pain, pelvic pain, or other symptom has completely subsided.
- Delayed phenomenon. There is no immediate improvement of symptoms. However, within 16 or 20 h the patient becomes asymptomatic. This is frequently observed in the treatment of asthma or in illnesses where an actual structural healing process is needed before the patient can become free of
- Reversed phenomenon. This is equivalent to the term "healing crisis" that has been used in homeopathy and acupuncture. The patient feels a worsening of his symptoms but starts to improve after 16 or 20 h
- Indication that the first treatment was given to a structure that is anatomically close to the correct interference field. There is complete improvement that lasts for less than 16 h. This phenomenon is extremely important to keep in mind.
- The last treatment was given to a correct interference This was, however, only a link in a chain of several interference fields. The patient's symptoms improve for more than 16 h, but the improvement is incomplete.
- The illness or pain is caused by an interference field. However, the interference field is anatomically distant from the site that was last treated. If an intervention was technically correctly performed and the patient experiences an aggravation of his particular symptoms (which can last for hours to several days), and then the pain or illness returns to the original state, this is referred to as "reaction phenomenon"  or "reactivation phenomenon." The illness is caused by a focus, and a careful interference-field search is in order.
- The last treatment was given to a particular link in a chain of interference fields. The next link reveals itself. This is referred to as "retrograde phenomenon"  or "regression phenomenon." For example, the patient experiences severe neck pain for 1 year. The cholecystectomy scar is injected. The patient calls next day and reports that she has a sore throat and the neck pain is unchanged. Prior to the onset of neck pain, the patient had recurrent episodes of "strep throat." The tonsils are injected. The neck pain improves to some degree but the patient develops pelvic pain. She had a pelvic infection 3 years ago. The pelvis is injected and there is some further improvement. Her appendix scar starts to itch. The appendix scar is treated and there is complete resolution of her pain problem. The appendectomy was done when she was a child. This is a true case of mine and indicates the importance of the patient carefully monitoring changes in his or her own body following each injection, writing them down, and communicating them to the physician on the next visit. It also requires careful listening on the side of the practitioner.
