In the twenties, the Huneke brothers (physicians) discovered the possibility of using local anaesthetics for therapeutic purposes as well besides being used to cause local loss of sensation (anaesthesia) normally. They then came up with the ''neural therapy according to Huneke'' which is considered largely suitable for eliminating any energy blockages in tissues since health is actually the defence against harmful stimulants and requires unhindered exchange of information to remain in a good state. The neural therapy is a regulatory therapy such as acupuncture or manual medicine and has been scientifically proven. A procain injection in the area of disturbance can heal the disease within a few seconds if possible from the anatomical point of view (immediate healing after the injection). For neural therapy, Dr. Wiechel uses certain homeopathic complex medicines besides the common local anaesthetics procain or lidocain, depending on the indications and therapeutic necessity.
