Recipe for “flying ointment”:

• 1/2 oz. soot
• 1 oz. pork fat
• 1 oz. hemlock
• 1 oz. deadly nightshade
• 1 oz. wolfsbane

Allegedly such recipes were obtained by torturing accused witches, who said they used the ointment to fly to the Sabbat. More likely the mixture induced hallucinations; maybe that amounts to the same thing.
