I personally fought MRSA for 5 months. I tried everything, to no avail. Then I read about Manuka honey mixed with turmeric. I couldn't afford Manuka honey, so I tried just plain raw honey and mixed it with turmeric.
I applied it to my sore and covered it with a bandage. I was amazed the next day, that it was actually starting to heal. Real raw honey is a miracle, it is full enzymes that started healing my MRSA.
It is important that that the honey has never been heated. Raw honey mixed with powdered turmeric into a paste, cover with a bandage. I changed my bandage daily. Slowly each day my sore got smaller, until it totally healed. It took about a week. I also, had to take sugar and white flour out of my diet, while I was trying to heal. I noticed that MRSA feeds on sugar.
So while I was healing, I followed a paleo diet, that helped my immune system get better.
