I wonder if the positive results are from a reduction in stress caused by believing (or hoping) that it will work? Stress can be a contributory factor to hot flushes and period pains, so this would explain why there have been some positive testimonies using ladycare for both problems.
I tried one years ago for severe period pain and it did absolutely nothing, but as my problem was partly due to a physical abnormality and partly to hormone imbalance, relieving stress would have no effect at all on the symptoms.
My view is if you are happy to spend that much money on the off chance, then great, and if it works, that is great too whether it is a placebo effect or not. Though I do have concerns over desperate women spending money they can't afford in a bid to get help. The only reason I bought the magnet was because I was getting brushed off by my then-GP and had run out of other options. If I had received the treatment I should have done from my GP, then I wouldn't have ended up hunting madly for any and every alternative treatment that might help.
