Snopes.com... so addictive a site. @.@

another riddle

This one seems to be a bit harder than the others... I modified it a bit from the original. Again, if you want to guess, comment without viewing other replies first. ;)

I have one trunk and a thousand branches,
And yet I have no leaves.
Water drowns and pulls me down
Yet I float on the breeze.
I am the body's warm companion
I am not there at birth,
Yet I am no beast's hide nor hair,
Nor plant upon the earth.
I am torn and cast aside,
Yet lay beside you in the night,
The blood that runs down through my veins
Is black without a hint of white.
