Very interesting. This contracts information I had read earlier that indicated that it does not cross the blood brain barrier. I wonder if they did any quantitative studies, so we could find out if only small amounts cross, or if it is more open. I wonder what form the silver was in. IE. maybe it crosses for silver compounds for not for colloid, or vice versa. Marshall -- The silver-list is a moderated forum for discussion of colloidal silver.
