Lots, lots more, if you want to extract.   One of the reasons MHRB is (was?) so popular is the relatively high yield, about 1-2%. So just 100G of material will get you a gram or two, enough for many doses. From what I've read the yield from viridis is more like POINT 1-3%. So a quarter pound of leaf will get you, at best, about .3 of a gram. Even if you only want enough for a single aya dose, I believe that's typically 50g. The bare minimum I've heard of using is 25g, and I'd expect that to be a pretty light dose. I'm planning on taking 100g soon myself (I seem to have an unusual tolerance). That looks like probably about a gram or two of leaf you've got there so far, so keep on collecting! :thumb_up:
