The powder stuff has a terrible after taste and the Z folded guaze is really chewy...
But seriously..... I think the treated guaze is the way to go. While the powder, QuikClot or Celox, has fixed the burned tissue issue it still gets everwhere in the wound. Granted, if a wound is serious enough to warrant it's use and help is not readily available there are worse problems at hand than removing the hemostatic agent.
In my opinion, one can never have too much medical training or too many medical supplies.
