I've honestly never heard of it used outside of the cardiovascular world to help with cholesterol, etc. But, I was able to find this study indicating you may be onto something:

Just remember that the mind is a powerful thing - many people can respond well or poorly because of the power of suggestion (placebo effect). If it doesn't happen to help, don't be so opposed to trying more traditional approaches as well.
After almost a decade in the pharmaceutical industry, I'd advice something with deep clinical information over those with only anecdotal experience. If you can't find a clinical study (respected) to support the findings, I'd always be a little cautious. Also, be cautious with OTC medications - most are not FDA approved and have little evidence to support their claims.
Good luck!
