MRSA +IODINE. WAS: heart palpitations. Was: For Venizia

[Guest guest]

I recently asked about whether iodine would kill a culture of MRSA. The

way I'm reading the results below is that Hibiclens, Acute-Kare and

Phisohex all failed to kill ALL of the MRSA. However, Betadine

[Providence-iodine] at 1 to 100 dilution kills ALL of the MRSA in a

culture. Is that how you guys interpret it?

So how does Betadine [Providence-iodine] differ from plain old iodine?
