Yeast Infections...

Now ladies...I'm sure everyone has had at least one, so I need some advice... how do you prevent yeast infections? If there's no monistat is there a natural way to rid of it? Is Summer's <a href="https://play.google.com/store/apps/details?id=com.glow.android.eve">Eve</a> or Lemisol a curse for the cooch?
