For a sinister Shakespearian brew to conjure spirits, you’re going to need to gather a variety of mystical herbs, like the scale of a dragon and the cool blood of a baboon (or maybe a spotted gecko). For eternal life, harvest a dead man’s toe and a newt’s saliva.
But if dry eye relief is all you seek, then the urine of a human fetus is what you’ll need—just don’t mention it to the Food and Drug Administration.
The regulatory agency posted a public safety notification warning people not to use eye drops with such ingredients—products more akin to hocus-pocus than modern medicine.
