Here's what I can made out from the lyrics of
"Medicinals" (I'm not a native English speaker, so I was using audio, a book and the picture from the spoiler):
"I was walking thru the National Mall
thinking about medicinals, how they used to grow there
When the ground was a marshland
Undisturbed by human hands, and I hear their voices:
Sumac said "We're always here"
Witch Hazel - "We're always here"
Sassafras - "We're always here"
Bluestem grass is always here
I looked around, and what I see?
Medicinals grow around me, rising from the gravel
Sumac and the Witch Hazel
Come to soothe our primal (?) sores, come to soothe our troubles (?)
Sumac said "We're always here"
Witch Hazel - "We're always here"
Sassafras - "We're always here"
Bluestem grass is always here
But do you see that woman, sitting in the wheelchair?
With her Redskins cap on backwards
What's that she's singing?
As from inside a paper wrapper
she sips from a bottle
a new painkiller
for the native people."
It is a great song. Gotta say, I don't understand why Polly took that brilliant last line about painkiller out of the poem - this text makes A LOT more sense for me now (back in time, americans used to "buy" land from Indians for "firey water", and now alcohol is a very cheap "social painkiller" in Indian reservations).
