Same with me -white threads - not mucous. The threads are very white and the drain in the morning, I also spit out or expel through the nose. I spend about 20-30 minutes in the morning to make sure its gone before continuing with my day and do not ingest any of it. Better out than in, ya know. I also flush the nose and sinuses with water several times to clear out anything that is left.
The yellow/golden stuff is, well rather gold in color and kind of crystallizes in the nose. My sinuses feel very clear. I wonder if it's leftover toxins being expelled.
I read in another post that someone was expelling yellow stuff in a colonic and this was a good sign. I wondered if the yellow stuff in the nose could be similar?
