It was a flying ointment, a mix of herbs and hallucinogens that "wise women" and "witches" applied to their skin and absorbed through their pores in order to "fly." Typical ingredients included belladonna, henbane bell, jimson weed, black henbane, mandrake, hemlock, and wolfsbane. It was rubbed on the skin and absorbed into the blood through the pores; the armpits are rich in pores and are a good place to absorb drugs like this. They contained chemicals like atropine, hyoscyamine, and scopolamine, which can cause psychoactive effects (they can also be highly poisonous).
