I probably will do that, but they'll be in the description on the right. This is mostly a screen real estate problem I think... and plus, I've always found it obnoxious in games when I have to learn new terms for basic items.
So I think what it'll ultimately say is something like... "Jogi Berries" and then a brief description of like... where they're grown and in what climate or something. But you can tell immediately from the item menu what it does.
I could also try to go with a smaller font, but I'm reluctant to do that.
