I am not sure what to make of "collected clay from trees" - sap? Lichens? Seems like a problem with the translation.

I assumed sap too. As a kid we had a load of sycamore trees - a close relative of the maple. My dad saw a documentary about tapping maple trees and he set out to tap the sycamore - it tasted vile.

But apparently Birch sap is fine, it seems to be enjoying a fad as a successor to coconut water at the moment.
