I'm personally a big fan of the don't ask, don't tell policy. Seriously, airline screeners are not looking for pot or herbs, their looking for weapons and explosives. Are these herbs in pill form or just loose? If their pills, I would just put them in an rx bottle & carry in my carry on just like I would any other meds I'm taking. It's for personal use, and it's not illegal, so I wouldn't even worry. (can you tell I've transported lots of stuff I shouldn't have?? lol)
