There're a lot of folknames for stuff like that. Like all the ingredients in the witches' potion in MacBeth are references to herbs (eg. eye of newt = mustard seed). One of my favourites is "baby fat" which is a rendered goose or duck fat used as a base for herbal salves (not fat from infants blood sacrificed on a Pagan altar like some retards believed it to be). It can be a bit challenging to decipher some old timey recipes because of that, and overlap in names, or multiple different names for the same plant, etc. But once it's figured out it's usually really a gold mine.
