Wild yam as birth control?

Using anything herbal is sort of hit or miss, and the reason why wild yam may work sometimes is you have to buy the the CREAM or pill, not just eating wild yams, and you have to buy something that contains progesterone. A doctor at the University of Maryland says it's nothing more then a nice herbal supplement, so it's probably doubtful it really works. Stick to condoms (which you should still use even on any sort of hormonal birth control like the pill) and abstinence right now, it's much safer then trying anything herbal.
