Mine is/was yellowish-to-clear. I agree---it didn't feel like a cold, because I otherwise feel great.
I took my evening dose a couple hours ago and about 15 minutes ago the weird sinus ooze began again, though only a mild bad smell this time. So I'm guessing it's related to some sort of cleansing/detox thing.
Wierd! And, lol, it is nice to hear that someone else was experiencing something similar. Fellowship of the Snot, I guess...? :)
