The commercial names of the products are TraumaDEX (modified potato 
starch) and QuikClot (zeolite).  They work by removing water from the 
blood at the wound site, concentrating blood platelets and proteins, 
allowing faster clotting.  The process is exothermic and the generated 
heat can cause problems if the products are applied too quickly.  A 
similar product, HemCon (derived from chitosan), is simply a sealant.

I suspect that TraumaDEX and QuikClot would happily remove water from 
whatever you put them in.
