Phenomena in the Neural Therapy

By Dr. Franz Hopfer

From Neural Therapy, Reflex Zones and Somatotopies: A Key to the Diagnostic and Therapeutic Understanding of Man’s Ills, a seminar guide compiled by the American Academy of Biological Dentistry, June 1989

In connection with neural therapy, the unprepared physician will again and again observe types of reactions in his patients which puzzle him, in fact, trouble him. He will not be able to assign them to either this or that kind of case. The Huneke Seconds Phenomenon is well-known. Beyond that, especially Hopfer has defined and described other types of reactions.

1. Huneke, or Seconds, Phenomenon

The Seconds Phenomenon is at hand when the following conditions are fulfilled:

  • By the injection of a neural therapeuticum into the relevant disturbance field, the totality of distant disturbances caused by it must disappear 100% in the same second, in as much as this is anatomically possible.
  • Full freedom from any complaints after such a treatment must persist for 8 hours in the tooth-gum area and for at least 20 hours in all other places.
  • In case the complaints return, the therapy-effect must be reproduceable 100% and must last longer than in the previous treatment.

Besides the 8 hour rule, the tooth-gum area shows another peculiarity: that it frequently acts as a disturbance field in the totality of its pathologic changes. It is therefore required that the tooth-gum area be tested in its entirety in one single sitting. Even then, there are frequently false negative findings in the tooth-gum area, in part depending on the technique applied.

According to Hopfer, one can notice a bi-phasic course, in general, in the Seconds Phenomenon. First happens an improvement like at one blow, which slowly diminishes and can reverse itself to a reactive worsening, lasting for hours or up to a day. When all the symptoms caused by the injection into the disturbance field are resolved, one may not infiltrate this disturbance field again prophylactically because therapy-resistant worsenings may be released (Hopfer).

2. Instant Phenomenon (Hopfer)

In the Instant Phenomenon, there is improvement at one blow. The other conditions of the Seconds Phenomenon are not fulfilled. The Instant Phenomenon may be evaluated as a pointer to the proximity of a disturbance field. Thus, in the case of an Instant Phenomenon by injection into the tonsillary poles, the focus may lie in the adjoining wisdom tooth.

3. Late Phenomenon (Hopfer)

The reaction happens only after hours, but otherwise, all conditions of the Huneke Phenomenon are fulfilled. Hopfer has frequently observed the late phenomenon in the treatment of the thoracic area. In his opinion, it is of equal value with the Seconds Phenomenon. According to Dosch, the Seconds Phenomenon is identical with the Late Phenomenon. The way he sees it, the disturbance field has been turned off in a blow, but the reaction at the diseased location courses slowly and the patient notices only after some time the diminishment of symptoms.

4. Reactions Phenomenon (Hopfer)

If a local treatment releases an increase of complaints, one should always consider a disturbance field. With these patients, one must not assume from the start a psychogenic illness, with the imputation that the patient is especially sensitive. To be sure, according to my experience, this local treatment should be repeated 2-3 times. Especially in the area of the shoulder belt, I have had to note at first an increase in pain, where there are pronounced pain syndromes. With the 2. and 3. local treatment came a distinct improvement of the complaints. We are here dealing with a reactive pain increase at the beginning of treatment, as it can also be noticed in massages, not a Reactionary Phenomenon. But if the worsening happens constantly, one must actually consider that the illness may be conditioned by a disturbance field. In this case, any further local neural therapy or physical therapy, etc., is meaningless. The guilt disturbance field must be found.

5. Retrograde Phenomenon (Hopfer)

Through the local treatment there occur suddenly pains in the causative disturbance field. The first Seconds Phenomenon observed by Huneke was a beautiful example of this. After a local treatment of the right shoulder due to massive pain, an osteomyelitis scar on the left lower leg, which had long remained without stress, showed an inflammatory reaction. The local treatment of the scar finally brought the desired healing success on the shoulder. Unfortunately, the Retrogenic Phenomenon does not always bring success. In the case of a 35 year old patient who had an irritable bladder and serious difficulties during cohabitation, I did not want to settle for a diagnosis of a psychosomatic illness. After a caudal anesthesia, there developed within 3 hours an isolated mastitis on the left breast. Hoping to have found the guilty disturbance field, I infiltrated the inflamed area. Thereupon, the mastitis quickly receded, but nothing else changed.

After several exampinations, a flapped ovarian cyst with inner bleeding (Einblutungen) was found, which had to be surgically removed. The further course has to be awaited; the old complaints continue on.

6. Euphoria (Hopfer)

The elimination of a disturbance field can bring about euphoria. This is not a medications effect. When the disturbance field elimination is repeated, the euphoria is normally reduced.

7. Compulsory Crying (Hopfer)

Compulsory crying after an injection occurs generally then when a disturbance field has been treated. The patient sheds truly crocodile tears. On the shocked question of the therapist as to whether he had hurt the patient so badly, the answer is always: No, it was not particularly painful, I simply must weep, I cannot suppress it. Also in the case of a successful segment treatment, a mild flow of tears can be observed. In some cases, the patient laughs and weeps at the same time. Again, we are not dealing with a medications effect.

8. “Knallkopf” (Hopfer)

The sudden reddening of the neck and head cranial of the clavicula, connected with a sense of heat, is a pointer that a disturbance field has been touched.

9. Tiredness

After a successful neural-therapeutic treatment, there may occur heavy tiredness within a half hour, forcing the patient to lie down. This is nearly always a sign that the treatment will have a good response.

10. Contralaterality

If the ipsilateral local and segment treatment brings no success, and no disturbance field can be discerned, then the possibility still exists for a contralateral treatment. According to Haenisch and J. Huneke, the attempt of a segment therapy on the contralateral body side, but in the same segment, is indicated, and especially so with phantom pains. The possibility of a bilateral or contralateral therapy is known also in acupuncture.


The understanding of these phenomena is important for the evaluation of the therapy effects. They are road signs for further neural therapy of a patient. It is especially important because in recent years the observation has been made that the classic Huneke Phenomenon seems to happen more rarely, even with experienced neural therapists (Gleditsch and Goebel). The causes for the lowered readiness for response to a targeted stress into the vegetativum are possibly to be searched in the increased stresses in modern environments. (Manifold sensual irritations, wrong nutritional habits, medications, damaging substances in the food, etc.)
