Neural therapy

Neural therapy is a form of alternative medicine in which local anesthetic is injected into certain locations of the body in an attempt to treat chronic pain and illness.

[1] According to Quackwatch, neural therapy is "a bizarre approach claimed to treat pain and disease by injecting local anesthetics into nerves, scars, glands, trigger points, and other tissues".

[4] The idea underlying the therapy is that "interference fields" (Störfelder) at certain sites of the body are responsible for a type of electric energy that causes illness.

[5] The practice originated in 1925, when Ferdinand Huneke, a German surgeon, used a newly launched pain drug that contained procaine (a local anaesthetic) on his sister who had severe intractable migraines.

[1] In segment therapy, a local anaesthetic in the form of skin quads is injected in the area of the corresponding dermatome (called Head zones) of the internal organs or into vegetative ganglia.
