I have a friend who paid over $200 for a batch of ginseng-based medicine and now wants to bring it with her in her carry-on baggage when she flies to the US (port of entry: Los Angeles). As the title indicates, it’s apparently a brownish powder in an unlabeled bottle, and a pungent odor that’s sure to drive the customs beagles crazy to boot. Am I right in telling her that this may be a Bad Idea?
Are there arrangements that can be made with Customs beforehand? Would it be better to mail the stuff?
