A great place to start the discussion of this ultimate healing modality (IMHO) is to understand its' basis.
The homeopathic medical model looks at disease as a disequilibrium of the energetic balance within the body (Vital Force, Qi, Prana, whatever you want to call it).
Unfortunately current medical science has not yet been able to quantitate this energy which helps all physiological processes run smoothly (and which is the difference between a living organism and a dead yet "healthy" one, i.e. one where there is no identifiable cause of death).
There are many similar forces in the universe which we know to exist (by observation) but which we can't really "see". For example we know that gravity or friction exist but what exactly are they (we can describe their effects but not what they are)?
Quantum physics on the other hand has dealt with (and explained) forces of this type for years. I *highly* recommend that anyone with interest in this topic read "Quantum Healing" or "The Field".
Anyway, I could go on and on (and usually do <g>) but that's not the purpose of this folder.
