Del,
I agree that oregano oil could work. I have also seen test info that it kills 
MRSA in vitro. I haven't seen any in vivo tests. 
I use a number of essential oils in addition to oregano because you get such a 
high concentration for a low cost. I buy the undiluted essential oils and like 
using coconut milk for dilution. It mixes easily since coconut milk is around 
50 percent coconut oil. And you get the benefit of the coconut oil.
