There is a great article in Canadian Family Physician, that refers to treating nausea and vomiting with magnets. They are placed over the accupuncture points, but are less invasive, and just as effective. I currently use magnetic products for numerous health benefits so I would encourage you to look into this link taken from that magazine http://www.cfpc.ca/cfp/2004/Jun/vol50-jun-clinical-2.asp Hope this helps.
