A second reason is far more cultural. The Mayans believed in ch’ulel, or sacred body fluids. Rather than being disgusted by their excretions and juices, the Mayans understood how necessary they were for life. As these alcoholic beverages already had religious meaning for the Mayans, their eventual excretion also had significance. Even vomit was sacred. The god of enemas wore a particular bib that appears in most enema scenes, apparently used for vomiting. Blood, vomit, water, and chih were all tied up in this belief in sacred bodily substances, and the wine seems to be used for ritual cleansing with both enemas and purges. The Madrid Codex shows the gods themselves performing boozy enemas. The Mayans may have performed enemas as a religious rite. In this case, we can more easily understand why it was a priority to depict the act in art.
Finally, they might have used enemas just to get drunk. There is some evidence that alcohol uptake into the bloodstream is quicker via the rectum. Chih was not particularly alcoholic, so large quantities would have to be drunk in order to bring on inebriation. Opting for anal absorption may have reduced the quantity of chih needed to reach the desired state of intoxication . In this regard, enemas optimized Mayan inebriation. Scenes of some enemas show the user smoking tabacco, perhaps heightening the enjoyment of the experience. Enemas, by this logic, were strictly hedonistic.
Aside from the Mayans and the related Huastecs, no other Mesoamerican culture is known to have practiced such enemas. The Aztecs did associate their version of chih, called octli in Nahuatl, with filth and defecation as well as blood and breast milk, but we have no evidence that they actually put it in their butts. How the Mayans came up with the idea is a mystery, but the stylized depictions of the affair in art and the commonness of enema syringes in Mayan imagery suggests that boozy enemas were an important part of Mayan life and religion. And why shouldn’t they have been? After all, it is just another way to absorb alcohol into the bloodstream…
