Minor public service announcement: IF YOU’RE HUMAN, DON’T EAT GRASS, EVEN AS A JOKE!
As in, the green stuff on lawns. Stuff like grains & bamboo shoots are obviously a different story.
It’s not toxic, but it’s A,) indigestible by humans meaning you have a non-zero chance of getting your intestines clogged, and B,) has tiny beads of silica in it as a defense mechanism against grazing.
That last one is how you can cut yourself just by walking through tall grass, BTW. They basically grow glass shard inlays or even thorns.
