 I was going to ask, how sustainable is it if you have to forage for it? In terms of standably harvesting the chaga, they leave 20 to 25% of it on the tree, so it can be regrown, be re-harvested. They actually GPS the trees, our wild foragers, so they can find it, so they know where it is. Especially 1 in 10,000 birch trees. Exactly. That's smart. So that's pretty much considered sustainably harvesting the chaga.
