Yes, we are talking about topical bentonite clay. In my opinion (actually in my knowledge and research), Purest Colloids Mesosilver and CZ sponsor Utopia Silver's Advanced Colloidal Silver are head and shoulders and then some above the rest - especially for internal use. Utopia Silver also makes an Advanced Ionic Silver which might be preferable for topical use.
Note that I have no connection to Purest Colloids and recommend it solely because it is such a superior product, though I do have an affiliate relationship with Utopia Silver (the owner is a lifelong friend). However, I receive no personal benefit unless I give an affiliate link to them, which I do not do in public support forums - and friendship and relationship aside, I would recommend their product regardless because of its quality.
