So I just did a quick google and am concerned that they would sell this without even notifying people that it is an ingredient. It can interfere with birth control, HIV meds, auto-immune disease medications, and umpteen other things and should only be used on medical advice

This wasn't the point of my post but I'm slightly horrified. How many people drink this without knowing?! Surely it would have to be a very small amount?

Is it ok for me to drink it if I'm breastfeeding overnight still?
