When traveling with homeopathic remedies, pass the remedies to the guard for manual screening and do not put them through the security x-ray scanners. Depending on where you will be travelling to/from - you could find out the EMR (electro-magnetic ray) strength used at each of the luggage and security line ups for each airport you will be travelling to. That way, you can decide which remedies you would like to carry with you or which ones you would like toput in your luggage. The lead bags that film is stored in for airport x-ray prevention may also be of use.
