Thanks. Reason I asked is that I bought a kilo during the Swine flu thing a couple of years back. I was not going to vaccinate (or ever will) so I stocked up loads of alternative stuff just in case.
Since we didnt have as much as a sniffle that autumn, I never got to use it.
Well, I guess there will be another round of scare flu, where I possibly can get a chance to test it.
