Although Hahnemann had discovered a new natural law he was forced to refine homeopathy in order to make it an acceptable form of medicine. Many of the materials tested were known to be poisonous and had to be diluted in order that they could be safely taken to establish their effect. Hahnemann found that many of the initial remedies he prepared worked in material doses but resulted in side effects. Naturally he diluted these down to minimize the unwanted action. However the results were disappointing, for in doing so he also reduced the power of the remedy to cure.
The next and most remarkable point in the story resulted in the process of potentization. Potentization is the combination of dilution followed by shaking in which a remedy's strength is ironically increased with successive dilutions. Hahnemann pondered about how the body cures itself, and discovered that it too was working according to the principles of homeopathy. We are chiefly composed of water as were his solutions. The main difference being that in our body the pounding of our heart resonates through this body of water. Taking his cue from the body, Hahnemann replicated the action of the heart by succussing (pounding) his dilutions of the remedy. To his surprise the effect was to enhance his medicine whilst getting rid of it's side effects. In actual fact he was removing all but the energetic imprint left by the original substance. In short Hahnemann had discovered that we are continually medicating ourselves and that what he had discovered was the vital force or means by which we do it.
Homeopathy was then simply a means of copying what the body does and therefore rectifying problems when it gets stuck, that is when we get sick.
