Neural Therapy is a method of diagnosing and treating illness and pain caused by disturbances of the body's electrical system. These electrical disturbances are called "interference fields" and may be found in scars, autonomic ganglia (or nerve junction boxes), and internal organs.
Interference fields have lower electrical potentials than surrounding tissues. Currents flow from areas of higher voltage to areas of lower voltage and seem to send confusing signals to the body's nervous system. The body will then sometimes react in inappropriate ways resulting in chronic pain and/or illness.
Interference fields can be found almost anywhere in the body and are often far from the part of the body that is experiencing symptoms. For example, an old appendix scar might cause migraine headache, or a wisdom tooth extraction scar might cause chronic low back pain. For the most part these relationships are totally unpredictable and interference fields must be searched for everywhere in the body.
How Interference Fields are Found
The traditional way of finding interference fields is by taking a careful history of the patient's problem. What one looks for is an injury, operation or illness in the months preceding the onset of symptoms. Presumably, part of the body's response to the injury or illness was a local "alarm reaction" involving the autonomic nervous system. The autonomic nervous system controls circulation to each part of the body and when an emergency arises changes circulation to that part. Interference fields seem to develop when the autonomic nervous system control does not return to normal (after the emergency is over).
Another way of finding interference fields is by making use of the body's electromagnetic field. The electromagnetic field of the body depends on the generation of electricity by healthy tissue. If tissue is not receiving adequate circulation, as in an interference field, it will be less vigorous and not have as strong an electromagnetic field over it.
The interference field can be "boosted" temporarily by another person (usually the physician), touching the spot with his or her hand. When this occurs there is a generalized inhibition of all the patient's muscles, i.e. they become temporarily weaker. The physician can therefore search for interference fields by touching possible spots and testing the patient's muscle strength at the same time.
Conditions Likely to be Caused by an Interference Field
The autonomic nervous system is that part of the nervous system that regulates the body's automatic functions. It helps control for example: heart rate, bood pressure, digestion, bowel movements, urination, sexual function, menstruation, perspiration and skin temperature. Any symptom related to these functions, such as palpitations, indigestion, constipation, or cold hands may have an interference field as all or part of the cause.
Chronic pain, especially migraine often has an autonomic component, e.g. nausea and sweating. One should think of an interference field if sciatica or any other leg pain is accompanied by coldness or change in skin colour.
If an interference field is found, it can be easily treated by injecting it with local anaesthetic. (Local anaesthetic has an interesting property apart from its ability to "freeze things"; it can also restore abnormal electric potentials or regulate unstable electrical membranes in living tissue. In fact, in conventional medicine it is routinely used for this purpose in treating certain heart problems.) The effect of injecting interference fields is immediate. There is sometimes sudden relief of symptoms (a "lightning reaction"), but usually if there is to be any response, it will be within the first few days.
More often than not, response to treatment of an interference field is temporary, sometimes even less than a day. However, even a very short response is encouraging and indicates that treatment should be attempted again. Each time an interference field is treated, there should be a longer response. Treatment is then repeated until eventually no further treatment is required.
Neural therapy is a remarkably safe medical treatment. The most commonly used anaesthetics (procaine and lidocaine) appear to never cause allergic reactions. Allergic reactions to these anaesthetics in the past seem to have been caused by preservatives (e.g.methylparaben). These are no longer used by most physicians practising neural therapy.
Occasionally patients will feel faint for a few minutes after neural therapy injections. This may be caused by "needle fright" or by a short-lasting lowering of the blood pressure caused by the -caine anaesthetic itself.
Puncture of an internal organ is a theoretical possibility with certain injections. Because the needles used are of small caliber, this is rarely (if ever) of any consequence. The one exception is the lung, which if punctured, may collapse. For this reason special care must be taken with any deep injection into the chest wall or near the lungs.
Another area of injection that carries a slight risk is the head and neck. Injection of a large volume of anaesthetic into an artery could precipitate a seizure. To avoid this, injections in the head an neck are always performed slowly, drawing back on the syringe from time to time to make sure the needle has not penetrated an artery.
Conditions Preventing Successful Treatment
The most common reason for poor response to treatment is the presence of a drug. Any drug with a prefix of "anti-" tends to block the autonomic nervous system, e.g. antibiotics, anti-inflamatories, antidepressants, antihypertensives, etc. Tobacco, alcohol and illegal drugs will block it as well.
Poor nutrition is another reason for unsuccessful treatment of interference fields. Inadequate nutrition is much commoner than most people realize. Mineral and vitmin deficiencies must be corrected or interference fields will either recur or the response to treatment will not increase with time.
A third common reason for poor response to neural therapy is the presence of toxins. Drugs and tobacco may be considered to be toxins, but environmental toxins such as herbicides and fungicides also affect some people. The metals in dental amalgam fillings, especially mercury, poison the autonomic nervous system and may defeat neural therapy.
Where Does Neural Therapy Come From?
Neural therapy was discovered and developed in Germany, starting in the 1920's. There exists a considerable body of scientific research to support its basic principles, unfortunately almost all of it published in German and never translated into English. It is a remarkably safe and simple method of treating many medical problems and is taught in German medical schools. Only in recent years have some in the English speaking world of medicine become aware of its existence.
