The same with me hopinso. I've tried oil of oregano, olive leaf extract, Colloidal Silver by the tablespoon and nasal spray, garlic, Iodine therapy, and on and on. I finally had to give in to allopathic control for a 10 day Antibiotic course. The first in my life. That cleared up much of the problem, probably bacterial related. Now I'm dealing with fungi, I'm pretty sure.
I assume you are going to activate it prior to putting it in the neti pot. Right?
The neti pot has not helped me; because most of the time at least one of my nostrils will not let the water pass. It closes immediately; even with salted water.
