It doesn't take much, and if you are leary, I'd start with just a little cayenne, where you can't even feel or taste it. I use it for Every infecton in me and my pets, and it hasn't failed yet. Wven made nose drops out of it before I knew there was something similar on the market, and opened a completely stuffed up nose in an hr with 3 apps, that each one opened me a bit. I was really condered since I had never heard of it's used in the sinuses, but I was despirate.
