Certain types of homeopathic remedies do make sense scientifically: these are the homeopathic remedies based on very tiny doses of normally highly toxic compounds, such as venoms, plant toxins, and so forth.
Because these toxins are so potent, even very tiny doses are likely to have a physiological effect. After all, that's the principle of botox: using incredibly tiny amounts of botulinum toxin for beneficial purposes, whereas larger amounts would be fatal.
And along these lines, there is increased scientific interest in finding medical uses of very tiny doses of normally toxic substances such as venoms.
Recently
@frederic83 told me that a
rattlesnake venom (Crotalus horridus)-based homeopathic tablet made by Boiron permanently improved his chronic food sensitivities. He said that when he first took the rattlesnake venom tablets, he developed flu-like symptoms for 3 or 4 days. But then after this, he immediately noticed he had much less intolerances to foods. For example, he said he could eat fruits again.
This I can accept, because scientifically it makes sense. The homeopathic tablets he used were the 4C dilution, which is which is one of the lowest dilutions (4C is a dilution by 10^8), meaning that there is still quite a bit of the substance left in the water. It is only when you get up to higher 12C dilutions (dilution by 10^24) that you find you no longer have any molecules of the original substance left in your solution, based on Avogadro's constant of 6.02 × 10^23.
So I think an exception might be made in the case of low-dilution homeopathic tablets having minute doses of very highly toxic compounds. However, in general, like most people here, I am highly doubtful that homeopathic treatments will have any efficacy, apart from these toxin-based homeopathic treatments.
