The brothers Huneke claimed the ‘fields of disturbance’, often old scars, injuries or sites of inflammation, can exert strong influences throughout the body which in turn can cause problems in distant body structures. Treating a particular problem may involve injecting Novocain or other local anaesthetics into one or two sites that may be ‘fields of disturbance’. When the correct site is located, the problem is cured.
Neural therapy is particularly popular in German-speaking countries. There are also many practitioners in the Spanish-speaking world, largely thanks to its promotion in the 1950s by a German-Spanish dentist called Ernesto Adler.
What is the evidence?
Injecting local anaesthetics into an area of pain will reduce that pain — but that is a predictable pharmacological effect and not what neural therapy is about. The concepts of neural therapy have little grounding in science, and the few clinical trials that exist have not produced any convincing evidence to support neural therapy. Occasionally, the local anaesthetic drug can cause adverse reactions, but such incidents are rare.
Conclusion
Although the injection of local anaesthetics as performed by many doctors can control pain, neural therapy is biologically implausible and is not backed up by sound evidence.
Orthomolecular Medicine
Background
‘Orth’ means correct, and orthomolecular medicine (also known as optimum nutrition) means administering doses of vitamins, minerals and other natural substances at levels that have to be exactly right for the individual patient. Proponents of this approach believe that low levels of these substances cause chronic problems which go beyond straightforward mineral or vitamin deficiency. These problems include a tendency to suffer from infections such as the common cold, lack of energy or even cancer. This means each patient is initially assessed to determine precisely which substances he or she needs. Subsequently the ‘correct’ mixture is prescribed. The hallmarks of orthomolecular medicine are the extremely high doses that are usually suggested and the individualization of the prescription.
What is the evidence?
Some of the diagnostic methods that are being used for defining the right mixture of substances are not of proven validity. For instance, hair analysis is often employed, yet it generates spurious results in this context. The medicinal claims made are neither plausible nor supported by data from clinical trials. Thus there is no evidence that orthomolecular medicine is effective.
Proponents would strongly dispute this statement and refer to a plethora of studies that show the efficacy of vitamins. After all, vitamins are substances that are vital for humans — without them we cannot survive. However, our normal diet usually provides sufficient vitamins and the treatment of vitamin deficiencies is unrelated to the specific principles of orthomolecular medicine.
In excessive doses, vitamins can cause harm. Virtually all of these substances will cause adverse effects if grossly overdosed over prolonged periods of time — and this is precisely what is recommended by proponents of orthomolecular medicine.
Conclusion
The concepts of orthomolecular medicine are not biologically plausible and not supported by the results of rigorous clinical trials. These problems are compounded by the fact that orthomolecular medicine can cause harm and is often very expensive.
Osteopathy
Background
The American Andrew Taylor Still founded osteopathy in 1874 — around the time when chiropractic therapy (see Chapter 4) was created by D. D. Palmer. Osteopathy and chiropractic therapy have much in common, but there are also important differences. Osteopaths tend to use gentler techniques and often employ massage-like treatments. They also place less emphasis on the spine than chiropractors, and they rarely move the vertebral joints beyond their physical range of motion, as chiropractors tend to do. Therefore osteopathic interventions are burdened with less risk of injury.
