I read a mess of artcles about the chemical composition wood distillates. There are 73000 types of trees and you need at least two reports for wet and dry distillates to know whats in the trees but generally food and fuel are at the top and muddle at 50 percent and the repellent antibiotic is at the bottom. 150 non cellulose liquid gallons of various cemicals.
Thats for dustillates but I think one more for unmolested tree juice.
