Prescription medicines should be carried in your carry-on, as others have mentioned

As far as spices go, you can put them in a ziplock bag or a small plastic container. I travel with spices this way all the time and have never had any problem. I often travel with spices that the average American hasn't heard of (the latest was sumac), and still no problem. But as a backup plan, ask your mom for the recipe for her spice mixture so you can make your own - I hear they have spices in Canada .
