Allusions to ancestral impropriety: understandings of arthritis and rheumatism in the contemporary Navajo world

Navajo people frequently attribute occurrences of arthritis and rheumatism to inappropriate contact with menstruating women or menstrual blood. During ethnographic interviews about rules governing contact with various types o f blood, Navajo consultants often explained these norms with allusions to k ey portions of the Navajo oral histories. The connections made by Navajo co nsultants in these contexts suggest that, like many other diseases, afflict ions such as arthritis and rheumatism are metaphorically linked to ancestra l impropriety or immorality. That is, particular actions on the part of anc estors of the Nihookaa Dine'e (Earth Surface People) are referenced as the precedent for considering certain types of menstrual and game animal blood dangerous to the health and well-being of contemporary Navajo people. In ex ploring the means by which these types of blood have come to carry such sig nificance in the Navajo world, I contribute to disciplinary concerns about more effective ways to study so-called menstrual taboos and demonstrate how language, bodily substances, bodily ills, human agency, and ancestral acti ons intertwine.
