Hello, George, Perhaps the term you are seeking is oligodynamism, the phenomenon of dilution increasing potency. The oligodynamism of CS was discovered (by Nageli) before the discovery of its pharmacological benefits for humans (by Crookes.) One possible explanation for oligodynamism is that the particulate envelopes itself with a multitude of layers of dipolar waters of hydration (lke layers of an onion.) These waters of hydration are not distinguishable by microscopy but are nonetheless contributory to the potency of the particulate. And they need ample spacing so as not to imfringe on each other. So dilution enhances potency. I have seen no compelling evidence for this theory; nor have I seen evidence against it.
