You can't get them at the moment. The functionality should be added in a future update. As for what they do I can't really say but this is my theory :

Elixir would restore your hit points/health and the horn might be something to reduce the waiting time of your fellow raid members between raids so that they can get back to the fight sooner. For example, say a person has to wait 20 seconds before attempting to destroy the Boss' shield again. But if you use the horn then they'll only have to wait 10 seconds.

Mind you, this is just a theory. Their actual function can be something else entirely...
