Homeopathy is over 200 years old!
Samuel Hahnemann, a German medical doctor, developed homeopathy over 200 years ago, in response to the fact that the medicine of the day was often making people sicker, rather than returning them to health (not unlike today where many diseases are being treated with drugs that have side effects that are worse than the original disease).   Homeopathy had a difficult period with widespread acceptance because the physics that makes it work couldn't be explained at it's inception.  However, today, homeopathy is at the leading edge and crossroads of physics, biology, and medicine.

 

It follows natural healing theory: 
It is based on an ancient natural healing theory first suggested by Hippocrates (circa 400BC) and later developed by Paracelsus (circa 1500).  This theory states that the body can be stimulated to heal a disease by a substance that can cause a similar disease.  To do this effectively, of course, the substance must be non-toxic! Hahnemann discovered how to make highly dilute 'remedies' non-toxic while preserving their abilities to stimulate living things. A remedy is homeopathic to one who is suffering from disease when the energetic property of the remedy is very similar to the nature of one's own disease. It is this homeopathic relationship of the remedy to the sufferer that brings about gentle but precise stimulation to heal.

Homeopathy & Advanced Physics:
Scientists have found that the procedure for creating a remedy produces structural changes in water, which persist at very high dilutions. The properties of such dilutions are the subject of advanced physics today.  Fully acknowledging and understanding the  physics of the properties of 'potentized' water, as homeopaths refer to it, has far-reaching implications and has attracted the attention of two Nobel prize winning scientists:

Physicist, Brian D. Josephson, likens it to liquid crystals, which while flowing like an ordinary fluid can maintain an ordered structure over macroscopic distances.

Virologist, Luc Montagnier, has established an institute at prestigious Jiaotong University in Shanghai to research this phenomenon. "What we have found is that DNA produces structural changes in water, which persist at very high dilutions, and which lead to resonant electromagnetic signals that we can measure.” This is a “new scientific movement at the crossroads of physics, biology, and medicine.”

Homeopathic remedies are FDA approved and available at pharmacies today:
While the flurry of research to explain the phenomenon is ongoing, we are able to take advantage of the technology right now.  Homeopathic pharmacies, in accordance with FDA regulations, manufacture thousands of these remedies today, each with a unique structure at the molecular level that is suited to a similar unique state of ill-health.   Remedies may be in liquid form, or dispensed on very small sugar pills which have been saturated with the 'potentized' water.
