I'm familiar with Dragon's Blood, but not in this context.  The only uses 
I've been aware of are incense and perfumery.  It seems rather expensive 
for this application.  That being said, it's easy to obtain large 
quantities, if you're thinking of a baseball-sized lump of resin.  It 
produces a sweet and fruity scent when burned.
