Hmmm, cornstarch. And cheaper than Quik Clots or Celox. Probably not a good idea for puncture wounds, though.
I've had a hard time sourcing sterile saline. Apparently it is a restricted substance available only by prescription in my state. The best I've been able to locate are 2oz squeeze bottles sold as sterile eye wash. I have one or two of these in my larger kits. But I like the bottle cap idea. In the winter it's likely that any liquids in my kit will freeze. Bottles of water are usually plentiful.
