lol would be awesome but no, pop culture has really done a number on our perceptions of what a potion is. a potion is a liquid spell, can be a tea, oil, bath, lotion, soup, you name it, as long as it's a liquid. it doesn't even need to be drunk.
as i've said on a few of these posts, good idea, but it's still just a spell, like candle spells or mirror spells. it can get annoying looking for them, so maybe a subcategory like with truth spells, or good luck spells. but i don't think a potion section is really needed. i specialize in potioncraft, and while it takes time to find potions, it's not impossible once you know what a potion actually.
