Hmmm, 12 uses of Dragon's blood ...

sounds like something a Potions Professor would know ...

and not ALL potions professors, but more likely, one that worked 
with DD many years ago, for many years ...

is it a coincidence that Slughorn joined Hogwarts staff?

the same Slughorn that taught Lilly & Snape, Arthur & Molly, and 
even Tom Riddle? 

Horace Slughorn has a lot of information just waiting for Harry to 
tap into.

Information on Horcruxes, Dragon's Blood (that he splashed on the 
wall), and what the heck all that Aragog venom is good (or bad) for

Slughorn plus the HBP text book could help end LV by Chapter 12 next 
book ... JKR better keep them away from Harry for a while to draw 
out our enjoyment   ;)
