Thanks to Hahnemannian444B for the useful references. I am not sure about your "Albert, Hahnemannian444 #5904".

I have expanded those references a little below, though I note that they do not particularly succeed with the objective of definitively answering the target question. We need a clear, repeatable & measurable effect, and that will be the objective of this topic.

Dunham's powerful force applied in succussing, Fincke's continuous fluxion and Skinner's interrupted fluxion. Hahnemann...Skinner's potencies are fine and provide us with the higher scale. Fincke potencies are excellent. They were Lippe's favorite. [http://www.lyghtforce.com/homeolist/00002015.htm]

Opinion of Lo's work:
http://www.sbu.ac.uk/water/homeop.html
"Explanation of homeopathy on the basis of water crystals (LO) is unconvincing as such crystals appear to be artifacts and, even as proposed, the effect of body fluid ions would be to immediately 'dissolve' them."
