Melatonin

no it is an amino acid hormone

You would get a headache and an upset stomach.

Melatonin can be used in the treatment of adrenal disease in ferrets.

Melatonin has been shown to enhance the full spectrum of the sleep cycle, including the deep cycles needed for the restoration of myelin sheath on neurons.

It is also known to induce apoptosis (cell death) of certain cancer cells.

Both cancer and CIDP share a common problem of an underlying systemic inflammation. It may be acting to reduce systemic inflammation as well, although this is a leap of logic but certainly a testable hypothesis for researchers.

It is a safe substance, even for healthy individuals, and it certainly does not cause

kidney damage like the standard immunoglobulin drug being used for CIDP.

I am not saying to avoid standard medical treatment, however, I suspect their are

natural substances that could be of huge importance to the management of this

cruel disorder.

I think its safe to say it does not. In fact this article http://endo.endojournals.org/cgi/content/abstract/144/12/5347 says the opposite.

Ambian CR (controlled released) is a prescription sleeping pill. Most doctors prefer this one over many of the older ones, since it has less potential for abuse. But, just like most prescription sleep aids, there is still some potential for abuse with this med. Melatonin is a hormone that is produced naturally by the body, which signals the body's natural circadian rhythms for sleep and wakefulness. When experiencing insomnia, whether due to stress, jet lag, etc., an increase in this hormone can help the body get to sleep more easily, and sleep better during the night. Melatonin can be purchased without a prescription in most grocery stores, pharmacies and health food stores, and can be quite effective in helping your body restore its natural sleep/wake cycle.

A pinealoma can disrupt the production of melatonin.
