I’m working on finding out. Harvested some at my parents’ cabin when I was there this summer. Had it in a paper sack in the trunk for almost a month and a half. A friend of mine said it needs to be charred- not like charcoal, but just to light a corner on fire and snuff it after a little bit. I’ll post results…Hmmm interesting. Given that, I wonder if just drying it out would be enough?
