(Inspired by the Herbalist’s Primer thread.)
My eyelids have gotten really hairy, recently. Must have been due to some strange herb I ate. Despite frequent shaving, the eyelid-hair grew longer and more tangled, at a truly alarming rate! The hospital staff couldn’t help, they just diagnosed it as IHES, idiopathic hirsute eyelid syndrome, and sent me home. In sheer desperation, I went to a dodgy back-alley doctor, who turned out to be a dodgy back-alley witch doctor. Luckily, she knew a cure, but before the witch shared the old family recipe, she first swore me to secrecy. Of course, the problem had only kept getting worse and worse, so I could honestly tell her that my lids were sealed.
