Interesting! But you have them for a reason, they are the mucus holding dead pathogens. Somewhere, gut? lungs? you have a hidden pathogen. "Occult Pathogenesis". The most common undiagnosed one is Candida or Candidiasis or Dysbiosis.
Before trying anything else, you should try any one of a number of Candida treatments. I believe in 28 days of 2 million units of Nystatin. And/or Itraconazole, and depending on where you live in the world, these are either cheap and over the counter or immpossible to obtain. I'm in Australia and it's somewhere in the middle. LOL.
