Supposedly Manuka honey has been used for a long time against but the only thing it did for me was feed the staph and allow them to obtain an even better foothold. It did not work. Oregano oil had no result but at least did not allow further penetration into the deeper skin tissue, so as I sit here with a draining staph wound because I have applied 15k ppm silver to its surface I would hope that others may gain insight.
