I just did about 30 minutes of research and on Science madness, one guy said from wood chipped roots 20 lbs, 240 ml of oil(?) if it's 80% thats like 192ml of safrole. 1.28 moles. Others said there is little oil in the wood and theres no oil it the bark above ground. Seems like a tough way to make a liveing, but there's value in extracting and purifying a bit just to be able to say you did. I'm pretty proud that I am the only person I have ever heard of, that has successfully extracted DMT from Illionois bundle flowers. And I collected, idk 5-6 speacies of hallucinogenic mushrooms (not counting muscarinic Amanitas, which I've found probably 5-6 species. Golden seal Spice bush, panax ginseng, black cohosh, Jimson weed, Paw paws, Walnuts, persimmons, ramps, I've eaten probably 40 species of wild mushrooms. Chestnuts, passion flowers, vaious berries and wild animals.......
