Nanoparticle homeopathic colloidals are ancient forms of medicine, the Egyptians were using silver in this form all thos years ago. There are a number of essential details in making a quality colloidal, without which it is doubtful if there is any real benefit for the organism. The nanoparticle size of all colloidal minerals produced by Christopher Freeland ranges from mono-atomic up to 10 nm (copper being the ionic exception) thanks to the large area anode plates used to make all products, and the sophisticated electrolysis device used. The reason for that is simple: molecules larger than 20 nm cannot pass through the barriers that protect most organs.
