Wade Davis, explorer extraordinaire, made his name as a graduate student at Harvard by proposing not only that Haitian zombies were real, but that they were created by ingesting concoctions that include tetrodotoxin, the toxin in pufferfish and the infamous Japanese delicacy, fugu. When the victim recovers (if he does), he believes he has become a zombie, and this belief is then taken advantage of by the voodoo priest.
Davis first reported his hypothesis, controversial to this day, in a 1983 paper. In that paper, he reports the results of three expeditions to Haiti, in which he documented the preparation of five separate zombie potions in four different villages. The process by which the potion is created is an elaborate and intricate ceremony, which the gentle reader may learn about by reading the aforementioned paper. For our purposes here, the interesting issue is the ingredients that go into the potion.
As mentioned above, Davis’s hypothesis is that tetrodotoxin is the key pharmacological component that causes a near death (or sometimes, too near) experience, but there are many other ingredients, and the recipe varies from one village to the next. One village, for example, included ground human bones and shavings from a dog skull and a mule tibia. More importantly, at least for our purposes, is how the potion is prepared. At least in one village, it starts by placing a toad and a polychaete worm in a container for a while; apparently the worm agitates the toad, getting it to secrete toxins from its parotid glands. The toad and worm are then killed and dried in the sun, alongside some pufferfish, the presumed source of the tetrotodoxin. The parched specimens are then placed on hot coals alongside freshly killed Ameiva and Leiocephalus lizards. These are then roasted and combined with ground human bones, and then a variety of other ingredients are added, including centipedes and tarantulas. I won’t go on, but there are many additional steps—read up!
At another site, the ingredients were much simpler—all animals. They included fish, tarantulas, frogs, a boa (Epicrates striatus), ground human bones and dried human flesh and—wait for it!—Anolis coelestinus and A. cybotes!!!
No doubt, one question is in your mind: how did Davis, then a graduate student in ethnotany, identify his ingredients? The answer, of course, is that he collected specimens and brought them back to the Museum of Comparative Zoology. The anoles, and other herps, were identified by the venerable team of Ernest Williams, Greg Mayer, Jose Rosado, Jim Knight and Franklin Ross. The photo above is the entry in the notes column of the MCZ Herpetology Department register for the anole specimens Davis entered into the collection.
