Is hoodia unique?

[tammybear]

There’s a lot of debate going on about whether or not hoodia really works, but as far as I can tell it isn’t actually much different than other plants that have a little bit of an appetite suppressing effect (assuming it works). Is it really unique in the plant world and, if so, how? Aren’t there other plants with less debate and more results?

hoodia is the latest in a long line of useless fads
