I bought safflower oil, and did my 2nd and 3rd pulls yesterday and today. Each time I do it, my post nasal drip gets worse for awhile. But I see that as a positive thing, not a negative one. I know the stuff is up there, and I want it out. My gums, while not in terrible shape look better. It's almost like putting an antioxidant and fatty acid rich moisturizer on your gums. I imagine the gums are a little like your skin, and they need those nutrients.
