Are there any biochemists around who know how blood reacts when mixed with acetic acid? I'm making up a potion recipe with goodies like root of black hellebore, grated Murtlap tumours, vinegar of rue with dissolved powdered pearl and the blood of a freshly killed blue salamander, and I'd like it if it didn't curdle or clot on me.

Okay, both Google and Jeeves have failed me on this, so I'm turning to you lot. (You have no idea how hard I'm resisting quoting Leia in 'A New Hope right now.)

I need to know what percentage of multiple murderers - not serial killers - are female. Can anyone help me on this?
