I have been having weekly acupunture for over a year now for numerous things, but not for allergies- which I do not have. But I can say that it is amazing in it's healing powers. I also have herb combos I take daily which are an important part of it.
I know that if I was not having the acupunture I would have had some medical problems now. This has nearly diminished them. It took some time to find the right combo, but it was worth it. I feel so much better.
Remember acupunture is an older type of medicine then our western one and instead of treating symptoms it really gets to the cause.
