Treatment Acupuncture for the Promotion of Fertility
What she says: Carey took up needling after a miscarriage in 2008. Happily, her first child is due this spring. "People who know me would be, like, 'You scheduled acupuncture at a certain time every day?'" she told Access Hollywood.
What science says: Studies are mixed and subjects were women who exclusively used in vitro fertilization. (Carey says she didn't.)

What science says: "Can we say from a scientific standpoint that a gem can help your body? No," says Dr. Bauer of the Mayo Clinic. "That said, if you want to hang an amethyst in front of your breakfast bowl, I can't argue too much. It's pretty."
