Homeopathy is not using diluted medicines. Homeopathy can be practiced with non-diluted medicines. Therefore, homeopathy is not energy medicine. If you believe diluted medicines work because of energetic qualities (for me the jury is still out on that point), then homeopathy is the utilization of this energy medicine according to clearly defined principles.
Homeopathy is a law of cure; in other words, the word "homeopathy" means cure is accomplished by using medicines in a specific manner.
