It’s common in fantasy books for characters to be wounded, and commoner still for said characters to experience miraculous cures from native plants. Sometimes these are authentic, like those in the Brother Cadfael series of historical mysteries. Others are fictional. Stephen Donaldson’s Thomas Covenant series had hurtloam, Tolkien had athelas, Narnia had the juice of the berries of the sun, held in Lucy’s diamond vial. There are more, I’m sure.
What a writer doesn’t want to do is mix up fictional ingredients with a real-world setting, as John Boyne did in his novel A Traveler at the Gates of Wisdom. In a passage about dyeing a dress, a historical character uses ingredients from the video game Legend of Zelda: Breath of the Wild: the tail of the red lizalfos and four Hylian shrooms. Luckily, the author was a good egg about it and promised to change it in the next edition.
If you’re looking for something that sounds impressive, but has nothing to do with Hyrule or any other video game, here’s some randomgenned suggestions.
