What is produced in the home using LVDC is a predominantly *ionic* silver solution, with lesser number of *colloids*. It's the ratio of silver ions to silver colloids that differentiates a colloidal solution from a predominantly ionic solution.
Silver ions are positively electrically charged hence they promote dedifferentiation of tissue and bone cells back to original stem cells, which regrows damaged bone/tissue in its original form. So called ' Colloidal Silver ' will not do that. The home produced stuff worked better for bone because of those Ag+ ions and not the colloids. Colloidal Silver has many uses and applications, but bone/tissue regrowth is not one of them, for that you need Ag+ ions, which is predominantly what you produce in the home, and that's also why one gets minimal or nil scarring.
Get hold of Dr Robert O Becker's book "The Body Electric", you will get a far better understanding of silver ions with regard to tissue and bone repair. So what you state regarding your home solution over the shop bought product being more efficacious in your case is correct, read this book and you will know why. Seek and ye shall find.
