Since Doug alerted me about this thread I have started typing a number of replies but to sum them all up; Training is more important than equipment. You can carry whatever you want in a kit, just make sure you have the training to utilize it. On that note, make sure you understand the ramifications of performing treatments that may be legally regulated.

On the cayenne pepper issue; I think your priority of carrying it and not have a compress dressing like the Israeli dressing is backward. There is a lot of anecdotal information that cayenne pepper can slow bleeding and improve clotting but no actual evidence. Again you can carry whatever you want in your own kit, but for the others here that are considering carrying cayenne pepper for medical purposes please do a lot of research before doing so.
