The segment therapy is among the treatments of neural. The Neural is an alternative healing method, which is not medically accepted. The goal of the neural is by making the local anesthetic on the vegetative nervous system to work.

The physician Ferdinand and Walter Huneke, which is developed around 1925, confirmed the Neural therapy. Ferdinand Huneke injected his sister who suffered from migraines, an intravenous anti procain instead of intramuscularly. Instead of the expected complications such as cardiac arrhythmias or seizures led to an improvement in migraine. Thus, Walter Huneke researched the effect of procaine. Thus, it came to the formation of the segment therapy. This therapy is usually the drug procaine, but also Prilocain or lidocaine is used.

Both are also local anesthetics. The active ingredients are in the ganglia of the Head's zone of bodies injected. The Head's zones are areas of spinal nerves on the surface; the various institutions can be assigned. These are in connection that brings in "figurative pain”.

They express pain, the internal organs out, in certain regions of the skin or muscles. The localization of the Head's zone is usually found in the proximity of each organ. However, there are exceptions such as the gallbladder, which the Headache zone in the area of the shoulder is real. As a result, the body is divided into different segments. The effect of local anesthetics thus refers to the vegetative nervous system of the affected segment.

Only on 1940 was again a woman of her particular complaints to the shoulder and migraines treated successfully through the use of procaine in a leg wound. As a result, the physician called to interference of the body. These are chronic inflammation, which may include other areas that influence the body. The treatment of these infections is considered perturbative field therapy and is another form of neural treatment.
