Boronia,
there seems to be some doubt as to whether Bach remedies are homeopathic or not. My understanding was that they weren't. But what you are saying seems to suggest they are. I wonder if we can get a definitive answer.
I'm sorry if I was confusing you. But what you are saying about no molecule of the plant being there means they are homeopathic.
You are right about hundereds of different factors coming into play in a pharmacological trial. But these factors are averaged away because the trial is done randomly.
