Hi John
Vaikunthanath Das Kaviraj has
done some work with this. In some cases the isotherapeutic remedy was successful - eg
Helix tosta on snails (and slugs) and some caterpillars - but the aphid instance is a good example of one that wasn't so successful. Instead he found that
Coccinella Septempunctata worked. This is the seven spotted ladybird which raises the question of hIPM or homeopathic Integrated Pest Management. Perhaps it is to early to jump at this as a principle but VDK seems up for pursuing it. When he made a remedy of the aphid he found it was OK but another aphid variety took over. Only when he potentised the ladybird did he get a result.
These are from the standard homeopathic pharmacopoeia so no problem getting them. But for those remedies not in the books you will have to make your own. I don't know of anywhere doing this commercially. I make up some at home and have alcohol and bottles ready for all this but I am in the UK. It's simple enough to do.
Enzo Nastati has written about bringing potentisation along from Hahnemann's day - not a person to shrink from a tough task. He has written a book called 'Le Basi per una Nuova Omeopatia' in Italian. English translation: '
Foundations For A Development Of Potentisation'. This takes the one bit of homeopathy which seemed fixed and shakes it - but comes up with some really interesting developments. It is written for those familiar with anthroposophy. I mention it because it has an appendix which goes into detail about making isotherapeutic remedies. He also has a set for various creatures and weeds based on Steiner's ideas about peppering against pests - see
the other forum. If you want a copy of this in English contact me off line.
I don't think the remedies would necessarily work in other locales from the one. Certainly the peppers are not necessarily universal. Glen Atkinson's experience with peppers for the common pests of Kiwi fruits suggest that the remedies don't travel well or last well. It all makes it very interesting but a little confusing. If only some one had put together a database of
what works ....
