Your point about everything being made up of vibrating particles is exactly what vibrational energy medicine is all about.
My personal view of all this is that if you look at quantum physics which supports the theory of all matter being made of vibrating particles, then the answer lies there although scientists themselves don't really understand it all yet.
Quantum physics also discusses the existence of at least 11 dimensions and possibly more. We are only conscious of living in 4 dimensions for most of our existence. To me, it seems perfectly reasonable that our thoughts, emotions and feelings could have specific vibrations that we are not aware of in our limited physical existence. As BFR are made from the essence of flowers, these would also vibrate at specific frequencies. Therefore, it is reasonable to believe that using BFR could 'tap' a negative emotional frequency to a positive one.
If you think about it, how exactly does any medication work. You might take 2 paracetamol tablets for a headache. We know they cause pain relief but how exactly do they work? If you take it right down the fundemental level, those 2 tablets vibrate at a certain frequency as does every cell, every atom in your body. That frequency might change once the tablets are in your digestive system, as they are being absorbed in your blood stream, as they act on nerve and muscle cells. The thing is how exactly do they act? How at intracellular level do they bring about an analgesic effect. I believe that one day we will find out that some sort of vibrational change takes place.
With reference to your link, Dr Bach who discovered the remedies was a very spiritual man and makes many allusions to the power of God and spirituality in his work. For me, I see this purely from the perspective of spirituality and not religion.
Finally, this is an excellent discussion but it has hi-jacked the thread. Perhaps we should move the discussion elsewhere? I wouldn't want andreax who posted the original message to think we are ignoring her concern for her child.
