Caroline, I read your link to insomnia and homeopathy with interest.

One thing which struck me is how often it uses Latin-sounding terms to describe common chemicals. Some examples are:

Kali Phos; this is potassium phosphate.

Natrum Mur; this is salt (NaCl).

Aurum Met; this is gold metal.

Arsenic Album; this is arsenic trioxide.

Baryta Carb; this is barium carbonate.

Are there any clinical trials which have shown that, for example, Arsenic Album (arsenic trioxide) is effective in treatment of insomnia?
