Good for you, glad you're over it, but can't say I'm convinced. That's what studies and control groups are for. Lots of people have died after following someone's anecdotal advice. Topical silver, though, has been demonstrated as useful toward external infections. Some oils such as Oregano have as well but you didn't mention what you were using.
I’m using Meluca ericifolia, thieves blend (proven to kill MRSA), and Melrose (a blend of other tea tree oils). Its the Young Living Oils blend. I didn’t use oregano because its a “hot” oil & my wound was very tender. Internally I took Inner Defense, which contains a blend of essential oils. I should say I’m not a doctor & don’t profess to be any type of medical professional. Everyone should do their own research & make their own decisions - just don’t blindly trust your doctor. Make informed decisions. I started looking into more natural ways of healthcare when my company switched to a high deductible plan. I decided to be in charge of my own health & do as much as possible to avoid doctors.
