Modern construction uses bindings of wire and string (instead of the traditional split withy) and the head is secured by a steel nail instead of a wooden dowel.
A number of different recipes for "flying ointments" have survived from the early modern period,[1] some of the constituents of which not only have hallucinogenic properties but are fat-soluble and could have been absorbed transdermally.
[4] Other tropane-containing, nightshade ingredients included the famous mandrake (Mandragora officinarum), Scopolia carniolica and Datura stramonium, the thornapple.
[5] The alkaloids atropine, hyoscyamine and scopolamine present in these solanaceous plants are not only potent (and highly toxic) hallucinogens of the deliriant class, but are also fat-soluble and capable of being absorbed through unbroken human skin.
[6][3] Another ingredient listed frequently in the various flying ointment recipes is the even more toxic Aconitum napellus, which has (among others) the English common name wolfsbane (i.e. "slayer of wolves").
