The lake that I like to swim at is has a nigh-bottomless supply of canary reed grass, and I know for sure that it is in fact phalaris arundinacea. I'm itching to give it a try, but I don't have a wheat juicer. I've heard that the highest alkaloid content is in the leaves, so I would probably just harvest the leaves; it'd be easier to send through the juicer as well. I'm wondering what the typical alkaloid content of the juice itself would be. I've heard that it's just not worth the effort, but I figure that if it works out well, I've got a free, abundant, and local supply of spice.
