Homeopathic remedies work the fastest and safest if they are as similar as possible to the diseased individual.
The law of similarity exists long before the beginning of homeopathy, as shown in the following examples:
Paracelsus (1493 – 1541)
“Only the poison is the cure”
Hippocrates (460 – 377 BC)
“Most diseases are curable by the very same factors as those from which they spring.”
