Ginger for Morning Sickness

I read an article about how researchers in Canada concluded that ginger was safe for pregnant women and would help to alleviate their morning (or as I call it, all-day) sickness. What's funny to me is that this research had to be performed, confirmed, checked, double checked. And then of course announced, scientific style. Hop on any pregnancy board and ask for ms remedies and most likely someone will tell you that ginger works. Be it ginger root, ginger tea, ginger ale, gingersnaps. Pregnancy is only nine months but the advice and so-called tricks of the trade don't often change.
