I've been trying to create my first brew of sweet wormwood tea, and I would like to attempt to remove at least some of the thujone from it; so, I decided to put it into a bottle with some 90% food-grade isopropyl alcohol and shake it up. When I did this, the powder became rock-solid and caked up onto the edge of the bottle. I used a stick to scrape a lot of it off, but at the bottom of the bottle it's thickly caked. Most of the alcohol is still in a liquid state, and the sweet wormwood powder is all hard like a rock in little pebbles and one big rock.
Why did this occur? Is any thujone actually going to be extracted? The plant material is ground to a powder, but it doesn't seem to be very wet!
About the container:
Just a standard PET bottle.
Well, it seems to be instantaneous. I put the powder in, first (one cup of powder), and then I filled it with an equal volume of alcohol. The alcohol was not visible when I looked in; so, I used a stick to attempt to stir it, and it was hard as a rock. I shook it, and the powder stuck to the walls of the PET bottle.
