Xylitol dissolves biofilm that is what my MD told me to use.
My doctor that is MD/ND said that there is NO WAY that fungus can be killed in the sinuses that they have to go into endoscopy sinus surgery to really kill it clean the sinus and sterilize it. Also he told me that sinus infection with Fungus are very very serious not to scare anyone and need to be taken very seriously before it effects the bones in the area!
