Thanks for the info and the many other
valuable information you provided (articles,
interviews with Dr. Schulz...).
I was thinking of somehow disinfecting that region,
e.g. using diluted tea tree oil. Although
tea tree oil is not supposed to be taken
internally, I once tried it on a serious canker
sore and it worked. Cayenne, garlic, and echinacea
make a lot more sense. Your valuable advice is much
appreciated!
