If you do not already use peppermint oil for sore muscles or for migraine-related neck/shoulder stiffening, let me praise its efficacy and encourage you to try some. Not only do you smell nice, in a candy sort of way, but it really loosens things up and alleviates tension and discomfort. You can get peppy oil at Whole Foods and a natural goods stores. Just make sure that you buy from a reputable source- that holds for all herbs, vitamins, oils and supplements! There's a lot of nasty stuff out there. Just recall melamine-infused baby formula in China. YIKES!
