It is a double blind study, so yes, i could get the placebo

But she did say it was more concentrated than anything that is avaliable commerically, and even if you are eating veggies, there are limits (i.e. eat only carrots etc and you get a build of carotene pigmanet in your skin).. and Alan said pure licorice extract in higher amounts can be linked to birth defects... So just cos its natural doesn't make is safe in high quanitites..

Thats what worries me...
