But -- post nasal drip *has* to be an "exit path" for lymph.
Quick google doesn't bring up an answer and I have to keep plugging away at work here, so can't chase it down to validate -- but here's what I'm thinking:
* We call this fluid "lymph" when it's circulating in our bodies
* We rename it "mucus" "generated by glands in the head" when it's in our sinus cavities/throat
Because we call it 2 different things we don't recognize that they're one & the same.
One function of lymph is to wash toxins out of our bodies. One of the symptoms of toxin overload is post nasal drip.
Post nasal drip is the lymph dumping toxins that it's washed out of tissues of the head, down the throat where hopefully the immune system around the gut can handle, or if we're sick enough, we cough it out.
One of the first detox effects I felt when starting Iodoral was pain in my salivary glands. Oil pulling did that at first too . . .
