Homeopathy, itself, is a vibration not a physical substance.
Many companies try to differ themselves by saying that they are 'vibrational remedies' not homeopathy. It is all semantics. All of these remedies fall under the category of vibrational medicine.
The whole principle of homeopathy rests on the fact that water is supposed to carry the vibrational essence of a remedy.
Many homeopaths are creating their remedies digitally now, either through a computer or a replicator. Some are using an anologue replicator. There is a great book on amazon.com by Savely Yurkovsky on amazon that really gets into all this stuff. I have provided a link here.
In essence homeopathy scares a lot of people because it is actually a free medicine. Unless there is some physical substance of the remedy remaining (such as a low potency plant bud drainage formula) then it is completely possible to replicate the remedy.
One famous alternative doctor I know doesn't use any equipment other than his own mind to replicate remedies. He states that homeopathy works on the Mental Field and therefore a concentrated thought works just as well as anything else to create a remedy. He even cited a study from Germany that showed the exact same effects between homeopathic remedies that were produced via succussion version remedies created via mentally thinking of the remedy.
A vibration can be copied or amplified in many ways, many using basic principles of light and sound physics.
