The very best part of the aloe vera is the yellow sap that kinda smells like bad BO. Not sure if it helps stop bleeding but it is great on cuts and other abbrasions, faster healing than the clear gel.
Oh thats real aloe I'm talking about too, not the bottled stuff.
And I thought my trusty aloe buddy had gone bad!! I'll snap a branch tomorrow and pinch my nose...
I use pure aloe vera as my after-aftershave (after jojoba oil) every day. I haven't found it to have any effect on bleeding, and I actually find it rather stings even on slightly irritated skin. (My bottle claims to be alcohol-free, but it sure doesn't feel like it. The ingredients list actually also has a few other chemicals, even though it's called "100% pure Aloe Vera".)
