Where better to find out than from its supporters? Here’s a pro-homeopathy alt med blog found via the Health Fraud List. This post from the blog outlines the “mechanism.”
Concerning the dilution of the remedy it says “Once we reach the 12C potency, according to chemical science, there should be no more physical substance left in the dilution……..Potencies above 12C work very effectively as though there was still a material substance present. Even though there is nothing left of the original physical substance, the medicine acts as though there were.” Then how could there be any biological effect? Reading on----“the vital force in the water, which now holds the impression from the original substance, acts upon the vital force of whoever takes the medicine.”
So, let’s see. The original active ingredient, though diluted so many times that no molecules remain in the water, leaves an “impression.” That impression is held in the vital force of the water, which in turn acts upon some vital force in the patient. Got it? Aren’t you glad this is supported by your tax dollars?
