The true cure comes from within, the cleaner the blood, the less the fungus. Externally peroxide will knock it down. Oregano oil internally and externally would be my choice along with lots of Olive leaf and liver flushes until it was gone.
I am working on an old herb that cured the 1918 flue, it is known to kill toe fungus by appling externally and taking internally, it is also known to knock out all viruses when nothing else can. I won't have any for sale for about 1 month, 1 to 1 and 1/2 ounces is suppose to stop pneumonia, distempter, hepatitis, etc. and just about anything, I have to see this to believe it, so far I have been amazed.
