Homeopathy: an Illusion beyond the Avogadro Constant

Abstract

Homeopathy was created in the nineteen century by the German physician Samuel Hahnemann. Since then homeopathy has not evolved. It is a doctrine without any scientific foundation. It has, however, supporters all over the world. The present article is a critical review of its vitalist principles, the lack of evidence for a “water memory” or structural changes in the water of homeopathic remedies as well as the most common errors present in homeopathy studies in which the absence of a placebo effect has never been discarded.
