Well now I'm conflicted...
As far as the medication itself it's just some bags with "morning", "lunchtime" and "evening medicine" on them. At a guess one's agar 35 but I don't really know.
I would like to keep up the continuity of treatment. I don't know if that's important.
Paul, hand luggage checks are interested in liquids and anything that could compromise airport/flight security. They are not bothered with any herbs. Assuming you are travelling within the EU you do not have to go through customs. So there won't be any further check.
Also, since you presumably do not have your litle bags hidden away in suspicious places but just normally placed in your bag and that presumably they don't look and smell like classified drugs I don't think anybody will care. There's no problem to have herbs or spices or loose tea or something in your bag. So why would Tibetan medicine be different?
Just relax.... and have a good trip....
