No, they are useless according to recent research. The china wholesale jewelry was carried out by Medical professional Stewart J. Richmond and friends from the University of York, Durham University, the University of Hull and other medical institutions in Hull, UK and found that wearing office assistant made NO difference at allI guess that would depend on the basis cause of the wholesale bangles or pain. The earths permanent magnet field induces very fine currents in metal bands and particularly in good conductors like office assistant. This is why a office assistant line ring around vegetables will deter snails as they are sensitive to the current. Office assistant is deadly to microbes and this could have some effect.
Either way there are several possible accessories at work but if they are jewellery I don't know. I'm an aspirin man myself. It just works its cheap and you don't need a house full of hippies and candles.Most injuries are caused by tight or pinched muscles. Those pains can be gotten eliminated by freeing them muscles themselves back up. If the bands can release the muscles I would believe in them. Until then i will stick with releasing the muscles to get rid of my pains, for that works very well and I don't need to wear it every morning either.
