Briefly let me explain my thinking. All matter, whether solid, liquid or gas, is made up from tiny particles. Hydrogen is atomic number 1 and consists of a centre proton with one electron circling it (in the way the moon circles the earth but held by an electrical changes). Helium is atomic number 2. It has a core (nucleus) of 2 protons and two neutrons and an outer shell of two electrons. This is quite a stable structure because the 2 posive charges of the protons balance the two negative charges of the electrons. And so it goes on.
The next element is Lithium atomic number 3 and it has 4 neutrons and three positively charged protons in its nucleus and three negatively charged electrons BUT of these electrons two are in the inner shell/orbit and the other is all by itself in an outer orbit. This makes Lithium very reactive as that poor little electron all by itself in the outer orbit is lonely and looking for company, as it were, and therefore will happily join with other atoms to make a compound.
And so it goes on. As each element in the periodic tables is progressively bigger and has more neutrons and protons in its nucleus and more electrons orbiting. These three particles, because they are smaller than the atom are therefore subatomic.
Now in addition to these three basic subatomic particles have been discovered even smaller subatomic particles. I really don't want to go there but they do exist.
Now my point is. The chemistry and physics involved in chemical reactions is complicated. For instance water is H2O, hydrogen peroxide is the addition of another atom of oxygen to form H2O2. Not simple as it looks. Compounds found in flowers are extremely complex. The idea behind homeopathy and Bach rescue remedies are that these complex compounds dissolved in water, alcohol, etc to the nth degree still contain some 'memory' of their original compound. This is patently ridiculous but they could easily still contain some subatomic particle from that original compound, iin fact it's quite likely.
So though I may not use these products myself (except for the time Thuga cured my verucca but that could be a coincidence) I would not completely dismiss them by saying they retain no trace of the oroginal compound as testing at this subatomic level is not feasible.
You did ask!
