I can add Oregano Oil, Garlic Oil, and Clove Oil to the arsenal you mentioned.
I was sick for years with recurring bronchial, sinus and typically developing to pneumonia. This would happen annually with a trip to the doctor, a dose of some kind of ever stronger antibiotic.
Then I cured myself and broke the cycle. The modern antibiotics seem to destroy everything in the body, yet cannot break up a slimy biomass in sinus, lungs or wherever. So the infection gets knocked down, but left to fester until the body gets tired, then to return.
Sambucol, Grapefruit Seed extract are wonderful. tea Tree oil, oregano oil and clove oil are great for brushing the teeth. Just a few drops on the toothbrush, then add toothpaste as usual.
I saw a study of nursing home residents with pneumonia, and they could match the cultures with plaque. So keeping the teeth clean is key.
I have not been sick since 2001 after being sick every year for the first 30 years of my life.
I don't care about organic, I just want it to be "real" food.
I haven't been sick in the last couple years.
What's your silver bullet for chronic bronchitis?
