Aaron,
Over the years I have had people try Zeolite, but honestly its sporadic. I feel, like, that the reports are more marketing than anything. I only mentioned it because it is popular and people will ask about it. Its also really expensive, or at least it use to be. Results…so so at best.
Colloidal silver I have seen help with infections, mostly throat and sinus. I don’t use it with many kids because of the unknown factor of metals.
Bentonite clay – similar to activated charcoal with regards to its die-off/bowel effects. I haven’t seen the difference between the two. I personally like the charcoal for the kids.
Sincerely,
Dr. Woeller
