I know this is an older post, but I had to put in my two cents..
A little history on this "flying ointment."
This "ointment" was said to be used by witches when they would meet for their sabbats. The ointment was made aconite, cinquefoil, belladonna, smallage, and hemlock. It was mixed with a paste made by fine wheat. This allowed them to "astral project" to meet each other on the astral plane. But these are highly toxic ingredients, and even the smallest amount could be very dangerous.
Its also been a very old and ancient technique to reach such a state of consciousness to listen to the sound of a croaking frog, as it aids in entering a trance like state.
Raven Grimassi's book "Witch's Familiar" goes into much more detail about the history and techniques from the late 1600's to present. This is where my reference came from. (I really recommend this author, by the way.)
