Pinworms:Parasites and Colliadal Silver

Hello, My doctor gave me Collidal Silver to take for pinworm problem I haven't seemed to be able to get rid of. Its called "Silver Shield" with Aqua Sol Technology it also says colloidal and Ionic. Dosing is 90 mcg/tsp.

My dosage is 2 tsp. 3 times a day.
I'm hoping this stuff does the trick!!
Anybody have good results from this stuff? Sorry, 2nd posting, just wanted to give more details on the CS.
