Hi AaronY, dunno what other/extra flavors I get from steeping as I have not compared the mixture with a freshly made batch not being steeped but it sure cleansed my sinus good! Today I can actually vape again my favorite juices, not a big fan of menthol and related but it did the job and I was able to vape as with my other flavors I would not taste anything. No, I have not tried Koolaid, never did and honestly don't know what it is as we have limited stuff over here.
