D'harans
I've been sick with a bad cold that causes headaches. Last night the headache was bad enough that it woke me up and I could not get back to sleep. My wife brought one of these patches in to give me some relief. Here are my thoughts. I felt an immediate cooling effect, though the pain did not disappear. But, it brought enough relief that I was able to get back to sleep. That alone was worth 4 stars. As other reviewers have written, I am also concerned about minimizing parabins in products. However, it depends on how you will use them. these come in a box of 4, which to me such a small sample, means they aren't intended to be used on a daily basis. For once in a while relief, I think they should be fine--- especially if you are not using parabens in your shampoos, body wash, deodorants, etc. However, if you need to use these on a daily basis, then I think you might search for a paraben-free headache patch. These work for me, though in moderation (like everything else).
