I know, it's gross for us newbies to toilet floaters, thanks for your reply - funny we both were surprised by anti-parasitic effects of something we were consuming! It seems that in our grandparents generation and before, it was a normal thing to get rid of parasites yearly with different types of remedies- a lost and forgotten art. Something I will be doing with my daughter for sure, after she's a little older.
I guess some of the parasites however have evolved to become resistent so some of those old remedies may not be as effective.
MMS - it's about $22.50 - I think from what I've read it's definitely worth budgeting for and it lasts a long time.
