Last November, I was able to complete the Basic and Advanced Course on Neural Therapy in the Institute of Neural Therapy (Sabadell, Spain) and was surprised how useful it is to learn about the Autonomic Nervous System (ANS or Vegetative Nervous System) and its role in about pretty much everything from the point of view of Neural Therapy or as it is also called: Regulatory Medicine.
Although most of my notes and resources are in Italian and Spanish, there are plenty of resources in English so as to give an idea to people about this healing modality which remains almost unheard of in English speaking countries.
The ANS is the most unappreciated system in mainstream medicine, yet it has to do with everything: how fast you heal from injuries, how pain is perceived, how is your digestive system working and every single system around. It connects everything and data shows that it can connect it non-linearly. That is, your autonomic nervous system works until the last straw that broke the camel's back comes (however banal that last straw is compared to other events in your life) and then, it becomes unregulated and chaotic, signalling diseases and conditions that to a mainstream practitioner might seem unrelated, or that he or she simply might even be unable to see with standard tests: endoscopy, ultrasound, scans, etc.
Think of the same science of Éiriú Eolas and how stimulating your vagus nerve can help regulate stress and then extrapolate to more disordered and recalcitrant conditions where something is used to help regulate the autonomic nervous sysstem. In this case, procaine ( AKA novocaine) is used, and not so much as a local anesthetic, but as wonder agent which acts as a crystalline liquid capable of reducing inflammation, resetting chaotic membrane potentials in diseased tissues and increasing blood flow to problematical areas so that the body can regulate itself. Procaine is also antimicrobial and has anti-tumoral properties, it also has a sympatholytic effect (anti-stress). There's something very special about procaine which helps regulate the ANS, well past its duration of action.
Here's more information from an American practitioner:
Neural Therapy is widely used in South America and Europe, although it is really all over the world. In some countries, it is covered by health insurance (i.e. Turkey, Germany?). It was pioneered by Russian scientists from the Soviet era and German scientists.
In the course, I witnessed how a man with ruptured tendons (he had the MRI with him to prove it) and was unable to lift his arm, was able to lift it up again after the neural therapy, which took about 10 minutes. That never happens in mainstream medicine practice. Yet it happened. As the trainer joked, thanks God I don't care about MRIs. The autonomic nervous system (AKA vegetative nervous system) is one heck of a system and Neural Therapy might be something to keep in mind for those who have recalcitrant conditons that don't respond to detox or nutrition. Even though it can have miraculous results, it is not a miracle therapy. It is just something that helps you regulate your autonomic nervous system, pretty much like stimulating the vagus nerve with breathing exercises help you relax, only that a step further so to speak. The person is actually the one who does all the work, procaine just helps regulate the resources of your ANS.
It also explains with common sense why looking at the mouth is crucial when there's disease. The trigeminal nerve, the Vth cranial nerve, is the cranial nerve that is most represented in the brain and its branches innervate the teeth. The masseter muscle, which helps you to chew, is the strongest muscle in the body. When there's tension from dental braces or an impacted wisdom tooth coming out wrongly, the tension created is such that it can frequently give unrelated symptoms. For instance, in a young woman or man with depression or anxiety, one should always look at how the wisdom teeth are coming out. However, it is not that a tooth has to come out or not, it is the lifestory of the person and the context of his or her complaints that has to be considered. In Neural Therapy, the person's history or life story is the most crucial thing to determine what to inject or not. That, and tension points pretty much like when you go to have a Rolf massage.

I hope this will serve as an introduction that might be useful for somebody. There are Neural therapists all over the world and even though there could be healing crises after the therapy, it remains overall a pretty safe tool.

Here's more information from an American practitioner:
Neural Therapy
Neural Therapy was originally developed in Germany by the Huneke brothers. It involves the injection of Procaine (also known as Novocain), a common local
www.drkaslow.com
How did Neural Therapy start?
The basis for Neural Therapy started with the use of cocaine as a local anesthetic in the late 1800’s by the great scientists, Pavlov and Sigmund Freud. In 1906, the German surgeon, Spiess, discovered that wounds and inflammatory processes subsided more quickly and with fewer complications after injection with the newly discovered Novocain (procaine), which did not possess the addicting qualities of cocaine.
The famous French surgeon, Leriche, performed the first nerve block into the stellate ganglion in 1925 for the treatment of chronic intractable arm pain. He described the injection of Novocain as the surgeon’s “bloodless knife.” Ganglion blocks are now commonly used for the treatment of neck, shoulder, arm, leg, and low back pain. In addition, Procaine can be used directly in the nerves of the autonomic nervous system, peripheral nerves, scars, glands, acupuncture points, trigger points, and other tissues. Even intravenous Lidocaine has treated chronic somatic pain, including cancer pain.
Modern Neural Therapy owes its discovery to an accident in 1925, observed and interpreted by two physicians, Ferdinand and Walter Huneke. They had for years attempted in vain to help their sister, who often suffered severe migraine attacks. During one particularly violent attack, Ferdinand injected his sister intravenously with what he thought was a remedy for rheumatism. While he was still administering the injection, the blinding migraine headache simply vanished, together with the flashing sensation in front of her eyes, dizziness, nausea and depression. Her headaches never recurred! After witnessing this miraculous recovery, Ferdinand and Walter realized their sister’s intravenous injection actually contained Procaine. After much further experimentation, it became clear that it was Procaine alone that had produced the startling cure, and therefore Procaine could also be used as a treatment remedy, as well as a local anesthetic.
How does Neural Therapy work at a site of disturbance?
A German neurophysiologist, Albert Fleckenstein, demonstrated that the cells in scar tissue have a different membrane potential from normal body cells, functioning much like a 1.5 volt battery implanted into the body. Whenever a cell has lost its normal membrane potential, ion pumps in the cell wall stop working. This means that abnormal minerals and toxic substances accumulate inside the cell. As a result, the cell loses the ability to heal itself and resume normal functioning. Procaine acts on the cell wall to allow the ion pumps to resume normal action and restore the membrane potential. This is how Procaine and other agents used in Neural Therapy correct the bioelectric disturbance at a specific site or nerve ganglion. By reestablishing the normal electrical condition of cells and nerves, the disturbed functions are also restored to normality, and the patient returns to health as far as this is anatomically still possible. The amazing part of Neural Therapy is that the site being treated can be very far away for the tissue in the body that is not functioning properly. For example, a scar on the chin can affect the low back. This is possible because of the vast network of nerves called the Autonomic Nervous System.
What is the Autonomic Nervous System?
The nerves of your autonomic system provide a vast network of electrical circuits, having a total length of twelve times the circumference of the earth, and connecting every one of your 40 trillion cells to form a living whole human organism. This autonomic (or neurovegetative) system controls the vital processes everywhere in your body. It regulates your breathing, circulation, body temperature, digestion, metabolism, hormone formation and distribution. It causes your heart to beat and your lungs to breathe automatically, even when you are asleep. It does in fact control all of the numerous automatic processes without which you could not live. In other words virtually every cell in your body is connected not only to each other through the autonomic nervous system but is also in large part controlled by your autonomic nervous system.
As Fleckenstein showed, scar tissue can create an abnormal electric signal. In turn this signal is transmitted throughout the rest of your body via the autonomic nervous system. Procaine delivered by direct injection to scars or through other nerves that travel into deeper scars through tiny tubules in the cellular matrix to these areas of bioelectrical disturbance for treatment. As a result, Procaine is capable of eliminating autonomic regulatory dysfunctions. Since the autonomic nervous system is the master controller of the body, Neural Therapy can have a profound impact on your condition and your ability to heal.
In 1940, Ferdinand Huneke observed the first “lightning reaction” or the “Huneke phenomenon,” discovering that a scar can produce an “interference field.” A patient presented to him with a severely painful frozen right shoulder that had been refractory to all kinds of therapies. Huneke injected the shoulder joint directly with Procaine without obtaining any pain relief. However, within several days of the shoulder injection, the patient developed severe itching in a scar in her left lower leg where she had surgery years prior and just before developing the painful shoulder. When she returned, Huneke injected Procaine into the itchy scar in her left leg. Almost immediately she obtained full and painless range of motion in her right shoulder joint. The shoulder problem never recurred. The left leg scar injection had apparently “cured” her shoulder problem. This was the first observation of what Neural Therapy is capable.
What causes interference fields?
Why does Neural Therapy work?
- Infections.
- Emotional trauma.
- Physical Trauma from any type of surgery, accidents, deep cuts, biopsies, childbirth, dental procedures, vaccinations, burns, tattoos, etc.
- You then may wonder how a scar or infection becomes activated to become an interference field. General stress from illness, malnutrition, emotional stress, food allergies, pregnancy, etc. seems to convert an inactive interference field to one that creates a disturbance.
I used to believe that if you get all the nutrients you need, avoid everything that makes you worse (allergens, alcohol, etc.), and detoxify or get rid of anything that is preventing you from getting well (mercury, yeast, abusive relationships), your body will heal itself. These were the three ingredients of attaining health. However, for some individuals even when everything has been done in these three areas, something seems to be interfering with getting well. It turns out to be interference fields from scars, trauma, etc. that are disturbing the instructions of the autonomic nervous system to heal the body. Emotional imprints are also considerations, but for the purposes of our discussion, we’ll focus on physical interference fields.
To understand this more fully, one has to understand that the autonomic nervous system is made up of two divisions. One division is the sympathetic nervous system that is activated by stress. It speeds up your heart rate, makes you burn sugar more rapidly, tenses your muscles, and in general increases your ability to “fight or flight.” The other division of the autonomic nervous system is the parasympathetic nervous system. Its job is to promote healing, digestion, repair etc. It slows your heart rate down, increases mucus and digestion, etc.
A key feature of the sympathetic nervous system is that it links all of the cells of the body together, regulates the contraction and expansion of blood vessels, regulates the activity of the connective tissue necessary for regenerating body systems, and it regulates the voltage (membrane potential) across the cell wall in every cell in the body. While either the parasympathetic or sympathetic nervous system could be overly dominant and lead to symptoms, most people are stuck in an overly reactive sympathetic state. In other words, the healing mechanism is impaired or “interfered with.”
Will Neural Therapy replace all other therapies?
I used to think that the biochemistry and hormones of the body directed the all of the metabolic actions in the body. What I now realize is that in fact the reverse, the autonomic nervous system is the master controller of biochemistry. Our personalized nutritional systems have allowed healing only to the point at which the nervous system will allow. Thus, when your interference fields have been addressed here with Neural Therapy, the results seem to be longer lasting and more complete compared to other practitioners using Neural Therapy. I suspect it is because of the attention we give in laying your nutritional groundwork. It is what has distinguished our practice from others. My current challenge is to find out the most effective nutritional ways to balance your nervous system so that you are optimized for staying healthy.
Neural Therapy is just another modality available to you. Combining it with a personalized nutritional/metabolic/detoxification program is one of the most powerful healing tools available.
How many Neural Therapy treatments are typically necessary?
Sometimes one treatment will resolve the problem. More often, only a partial improvement follows each treatment. Three to six treatments are the average number to achieve lasting resolution of a chronic condition. What Neural Therapy does for many of my patients is to open the door to allow the other healing modalities to finish the job. Less often do I see the dramatic miraculous response that the Huneke Brothers described. Rather it is a gradual resolution of the dysfunction and a return to optimal health.

Summary:
Because of the inner connectedness of every cell through the sympathetic nervous system, now matter how seemingly distant from each other, it is truthful to say that any illness indicates that the living organism as a whole has lost its ability to regulate itself in a completely healthful way. An organ (heart, gallbladder, eye, joint, etc.) never becomes diseased in isolation, but always as a symptom of the whole individual. My task is to provide your body nourishment and, if necessary to remove any interferences, so it can regulate itself and heal itself to your highest function.
Neural Therapy is widely used in South America and Europe, although it is really all over the world. In some countries, it is covered by health insurance (i.e. Turkey, Germany?). It was pioneered by Russian scientists from the Soviet era and German scientists.

Here are more quotes from a paper published in Acupuncture and Related Therapies.
There are multiple interrelationships between neural therapy
and acupuncture. Both are minimally invasive, both have knowledge
of distant phenomena, and both have few side effects. They
are both forms of regulatory therapy and aim to influence the whole
organism by following a holistic approach. This review summarizes
the scientific and clinical evidence, indications, methods of
application, and possible future research in this field...
Local anesthetics have a multitude of effects on the nervous
system. Beside the well-known action on sodium ion channels in
excitable cells, they also seem to provide neuroprotection to the
CNS [4], protect against sympathetic sprouting in neuropathic pain
[5], and reduce intracranial hypertension [6].
There is some evidence in basic science that pleiotropy (i.e., the
“alternative effects”) of LA on non-excitable cells [7,8] has a longer
lasting effect than the pharmacological half-life of the drug in the
sodium ion channel.
Some studies have revealed additional molecular mechanisms
in neural therapy. Local anesthetics induce Gq–protein-complex
mediated intracellular anti-inflammatory mechanisms,
deactivate overactive granulocytes, inhibit the signaling of
human NMDA receptors [10], and affect the synthesis and
release of inflammatory mediators as eicosanoids, histamine,
prostaglandins, and cytokines [11]. LA induce vasodilatation [12],
reduce a pathologically increased capillary permeability in a
hyperoxic lung injury in rabbits [13], have antimicrobial properties
[11], and exhibit a sympatholytic effect [14]. Furthermore, the
interesting concept of neurogenic inflammation [15] opens new
perspectives into the therapy of chronic sterile inflammation by
local anesthetics, thereby reducing the release of pro-inflammatory
substances. Although Tracey has already suggested this approach
[16], there are no data available proving this idea.
Neural therapy works best if it is repeated several times with
increasing intervals as complaints are decreasing. This concept
of “salutogenesis by pain holidays” (Fig. 1) may reflect the central
nervous system action of local anesthetics. Memory effects are
important mechanisms in the development of chronic pain disease.
A central mechanism of LA action is likely. Procaine, for instance,
shows a selective proclivity for activating limbic structures [17]
without inducing the adverse effects of cocaine
[Indications]
5.1. Acute pain and chronic pain disorders
Headache and migraine can be addressed by injections to
the major occipital nerve [3] or by the intranasal or intravenous
application of lidocaine [28,29]. Trigeminal neuralgia has been successfully
treated with 10% lidocaine injections [30] and with trigger
point injections [31].
Postherpetic neuralgia (PHN) could be successfully treated
with local LA injections. Early reports [32,33] were confirmed by
recent studies using neural therapy with procaine in amultifaceted
integratedCAMconcept [34]. Inmost recent studies, however, neural
therapy was only used in combination with steroids [35,36];
therefore, a clear conclusion on the value of local anesthetics alone
cannot be drawn. A promising approach to ophthalmic PHN is the
topical use of lidocaine in eye drops [37]. Similarly, the topical use
of 5% lidocaine plaster has been established as a first-line option
for treating patients with PHN [38].
Myofascial pain is characterized by the frequent occurrence of
muscular trigger points; in fact, myofascial pain and trigger points
are nearly synonymous. One of several publications on successful
LA use in this disease was conducted in Taiwan, with cervical facet
joint injections for shoulder pain [39].
Visceral pain. An important example of abdominal pain conditions
is chronic pelvic pain without organic origin. A French group
reviewed the literature and found a significant diagnostic effect of
autonomic nerve blocks (ganglion impar, hypogastric plexus and
L2 lumbar sympathetic blocks) [40]. Further research may reveal a
therapeutic effect in repeated interventions.
Postamputation pain syndrome. There is some evidence that
contra-lateral injections of LA relieve phantom pain in soldiers [41].
Recent observations support the idea of treating postamputation
pain with LA [42].
5.2. Functional disorders without organic findings
Vulvodynia. Clinical experience in our unit (with 10 patients)
yielded the first evidence that LA injections around the pudendal
nerve and the hypogastric plexus provided long-term relief of this
painful condition [43].
Chronic colitis. In a review with description of their own experience,
a Swedish group [22] described the results of a treatment of
colorectal mucosa with a topical application of 2% lidocaine gel. The
clinical results were promising and no side effects were observed.
Reportedly, tinnitus may respond well to the application of
local anesthetics. The first known publication reported on successful
nasal application of procaine (Barany, 1935). In a recent report,
a Japanese group performed intravenous lidocaine injections with
good success [44].
5.3. Vegetative (systemic) disorders
“Sympathetic pain” describes sympathetically induced vasoconstriction,
ischemia, tissue damage, and chronic pain in the
respective area. Well-known examples are reflex or vasospastic
disorders, such as Raynaud’s phenomenon and thromboangiitis
obliterans (Buerger’s disease). Early sympatholysis with LA injections
or infusions to the respective ganglion or artery is an
auspicious method of relieving these conditions [45,46]. Also
causalgia and reflex dystrophy (Sudeck’s disease, CRPS) are vegetative
disorders. Therapy with LA injections to sympathetic ganglia
is a promising approach for relieving these severe conditions
[45,47–49].
Probably, based on clinical experience, also non-specific vegetative
disorders, such as menopausal flushes, can be addressed with
LA injections to the sympathetic ganglia. Case reports are available,
but there is no available RCT data.
5.4. Chronic inflammation
Following the encouraging results on the anti-inflammatory
effects of LA in basic research, a Swedish group has collected 227
publications on the physiological and clinical effects of LA in inflammation
[11]. They report on its strong effects, e.g., in treating
interstitial cystitis [50], major burn injuries [51], and in recurrent
HSV-1 and HSV-2 infection [52].
5.5. Miscellaneous indications
Oncology.Someclinical units in Central Europe use the systemic
application of procaine infusions for secondary prevention. They
report on good results and refer to in vitro findings that support
an anti-tumor effect of this substance in different tumor cell lines
[53,54] and in mesenchymal stem cells [55]. Obviously, the amidlinked
LA lidocaine has DNA-demethylating properties [56], too.
Alzheimer’s diseasemayalso be a promising indication for neural
therapy. Lecanu et al. in Washington, DC, demonstrated in vitro
that procaine protects rat cells against beta-amyloid-induced neurotoxicity
[57], which suggested a potential preventive application
of procaine in early Alzheimer’s disease. However, no clinical trials
have been published yet.
Hypercortisolemia and stress therapy. An increase of ACTHcortisol
and prolactin by procaine was suspected by an NIH group
in the 1980s [17]. In contrast, the Lecanu group showed the inhibition
of adrenal cortical steroid formation by procaine [74]. Further
studies are necessary to explain this discrepancy.
Wound healing can be improved by local anesthetics in vitro
[55]. In our university hospital, the systemic application of local
anesthetics was shown to reduce the length of postoperative hospital
stays after colorectal surgery [58]...
For didactic reasons, the application of LA can be divided into five
different administration methods. Similar to acupuncture, in daily
use, these methods are not purely applied; instead, most physicians
combine two or more methods in their therapeutic regimen.
6.1. Local and trigger point infiltration
Injections into trigger points and tender areas (ligaments, fascia)
were first described by the authors of The Trigger Point Manual [59]
and are frequently used in pain therapy, e.g., in chronic pelvic pain
[60]. This approach is similar to the acupuncture of ASHI-points.
6.2. Segmental therapy
This form of neural therapy aims to exploit segmental reflexes
and referred pain mechanisms. It resembles needling of the bladder
meridian in acupuncture. Administering wheels (“quaddles”) into
the HEAD zones and infiltrations into intervertebral (facet) joints
[39] are the main techniques in this context.
6.3. Regional therapy
Regional therapy compromises all injections in or around nerves
and ganglia. Many complex pain syndromes are induced or maintained
by sympathetic overweight. Injecting local anesthetics into
the respective ganglia can reduce an increased sympathicotonus
and re-establish the autonomic balance. In a doctoral thesis, our
group demonstrated this effect through the enhancement of heart
rate variability (HRV) shortly after neural therapy compared to a
waiting group [61]. A well-known example for the clinical application
of regional therapy is the successful treatment of CRPS and
chronic pelvic pain (see above publications). Another example for
regional therapy is performing paraurethral injections in motor or
sensory urgency in female patients [62].
6.4. Systemic infusion therapy
The main indications of LA infusions are chronic pain disease,
tinnitus, the prevention of post-surgery ileus [63] for lidocaine,
and acute pancreatitis [23] for procaine. LA infusions also seem to
increase the general pain threshold, which is usable in otherwise
intractable chronic pain [64].
6.5. Stoerfeld therapy
The most sophisticated but otherwise irritating concept is stoerfeld
injection therapy. A stoerfeld (German: “Störfeld”, English
also “interference field”, “disturbance field”) is defined as “any
disturbed structure of the body being asymptomatic but inducing
or maintaining another disorder by remote effects” [65]. Important
examples for stoerfelds are scars, as well as organs with chronic
inflammation, particularly the teeth, sinuses, and pharynx. The
autonomous nervous system (ANS) seems to play an important
role in the information transfer from the disturbed area to the
target region of complaints. Case reports suggest that stoerfelds
and their remote adverse effects can be temporarily or permanently
eliminated by injections of LA [66]. These authors used
LA injections into the area of the wisdom teeth for diagnostic
methods to prove or exclude remote effects. In cases of repeated
positive responses to this “stoerfeld test”, the wisdom teeth were
removed, with remarkable improvement of clinical complaints in
these patients. In another approach, our group showed that LA
injections to the sinuses and the oropharyngeal region significantly
reduced the tenderness in the cervical spine. We called this special
type of tender points of the cervical region neck reflex points
(NRP). These results will be published in a doctoral thesis [67].
There is some evidence that oropharyngeal disturbances may be
a preferred site of developing stoerfelds and may become a major
remote cause of chronic diseases [68], perhaps based on the intensive
interrelation between the dental region and the ANS [69].
Neuralgia inducing cavitational osteonecrosis (NICO) is a term coined
by Bouquot from Houston, TX, for a dental focal disease that induces
remote adverse effects, thus precisely meeting the definition of a
stoerfeld [70,71].
I hope this will serve as an introduction that might be useful for somebody. There are Neural therapists all over the world and even though there could be healing crises after the therapy, it remains overall a pretty safe tool.
I hope to post more information as I go through my notes and books. It is really something that helps to approach health vs disease in a non-linear system/point of view.
