Decline of Divination Practices Using Psilocybe Mushrooms in the Chinantec Region of Oaxaca, Mexico
摘要
We documented current use of Psilocybe mushrooms through in-depth interviews with people selected via snowball sampling in Santiago Comaltepec and La Esperanza, and with a person who migrated to Valle Nacional. The interviews revealed current practices involving mushrooms locally known as Níẗ dsia jiun. The findings show a significant loss of ethnomycological knowledge, now confined to the memories of elders and a small group with the innate gift of interpreting visions, a skill considered non-transmissible. These mushrooms were traditionally used in divinatory rituals to address personal and community issues. Their presence in nature has diminished, possibly due to rising temperatures that affect their growth cycles. We conclude that modernization, local perceptions of climate change, and the lack of intergenerational knowledge transmission are accelerating the loss of ancestral traditions deeply tied to Chinantec cultural identity.
