I have been battling a chronic lung infection for many years.
To make a long story short. I have recently been diagnosed with a golden staph infection.
I have found oregano oil kills golden staph. It should also kill many other organisms which cause chronic lung infections.
I suggest you take it.
You take just drop doses.
I suggest you continue taking it for several months after the symptoms are gone, to completely eliminate the infection.
Something else which should also be beneficial is eucalyptus oil.
