Potassium aluminum sulfate. $9.00 for 3 x 5g jars. That's about $272/pound (454g). You can probably find a pound of food-grade chem for $10 or so online with little trouble--just not packaged in the tiny jars for 30x the actual value. For minor bleeding only (that manual compression will easily stop, too). For papercuts and bleeding close-clipped dog nails. You'll never use a whole 5g jar in a lifetime (at least it doesn't get old). There are other products for moderate to severe bleeding that are not this, and of much more utility. If you think it could be useful it's also available in styptic pencils for treating razor nicks, which is probably easier to carry and administer than jars of powder/crystals. And they start at $2.88 for 2 (only $69/pound!) and will do the same thing. https://www.amazon.com/Pinaud-Clubman-styptic-pencil-relief/dp/B000YM76VU/ref=sr_1_9?crid=2LRJIZZ7RR2NF&keywords=styptic+pencil&qid=1687322779&rdc=1&s=beauty&sprefix=styptic%2Cbeauty%2C298&sr=1-9

There's also a ton of otc quick-clot treatments for mild bleeding that don't sting like alum does...it burns like an s.o.b.
