Are there any clinical studies on neural therapy?

Not aware of any. Neural therapy is widely practiced in germany & used by a relatively small number of doctors in the us. I am not aware of any clinical studies conducted on this. Practitioners (including myself) who practice this commonly observe remarkable improvements as a result of this simple & safe therapy. But studies cost money & no one is sponsoring any.
