I made the Xylitol Nose Spray as advised here to try to stop my nose from running. At the time I didn't manage to open the spray bottle I had bought so I left the solution in a dark colored bottle, not in the frige for a few days. When I was pouring it into the spray bottle I noticed a lot of dark bits a bit like little mosquitos and a lot of clouds floating around in the dark, glass bottle so something went wrong. I used grapefruit seed extract as directed but the ones you buy here don't state any precentage. Once I read that in order to use it as a preservative it should be 60%. Could that be what went wrong or the fact that I didn't keep it in the frige? As I have a lot of allergies or whatever that make me sneeze a lot and my nose run, often during the night or first thing in the morning I was interested in trying. Xylitol nose spray is not sold here in Europe!
