My sinuses have opened a lot since I started deworming. My nose used to seal up every spring for 2-3 weeks. I'd get addicted to Afrin nasal spray. That doesn't happen any more. When my nasal passages weren't completely sealed off, one side of my nose was always plugged. Now I can breath through both sides. I was told I had nasal polyps. I read the old timers used bloodroot as snuff to get rid of nasal polyps so I tried it. it is not for sissies. But it will make you expel a lot of mucous along with stringy bloody boogers that kinda look wormy to me. It doesn't take much, either, just a pinhead amount.
