Kill biofilm by using black tea, I think 1% baby shampoo does the trick. I believe fungus can be killed by OZONE injections into sinuses, combined with the amazing nasal simpatico treatments.
My doctor that is MD/ND said that there is NO WAY that fungus can be killed in the sinuses by irrigations he said that that to really kill it and get the area sterlized you need Endoscopy sinus surgery.
I so hate the ENT departments the Med university School here charged my insurance company close to grand for a 20 minute appointment to shine a small light up my nose, I paid 20.00 co-paym, but wow what a racket!
Sorry I digress , my doctor told me that sinus infection with Fungus are to be taken very seriously before it effects the bones in the nasal area and spreads.
