Thousands of Argentines drank a mixture of sugar cane and rue this Saturday to ward off illness and attract good fortune [1].

The ritual, observed on Aug. 1 [2], serves as a cultural bridge to the region's indigenous roots and the spiritual honoring of the Pachamama, or Mother Earth [3].

Families across various regions of Argentina, particularly within the Rio de la Plata folklore tradition, consume the infusion on an empty stomach [3, 4]. The practice is intended to protect the health of participants, and ensure prosperity for the coming year [3, 5].

To follow the tradition, participants typically consume three small sips of the beverage [6]. The drink is a combination of caña, a distilled spirit made from sugar cane, and ruda, a bitter herb known as rue [4, 5].

Luis Capeletti, an anthropologist, said the concept of the caña con ruda comes from pre-Hispanic South American worldviews [6].

While the practice is rooted in ancient beliefs, it remains a widespread social custom in modern Argentina. The ritual focuses on the transition of the season and the desire for protection against the physical and spiritual ailments often associated with the winter months [3, 5].

The ritual, observed on Aug. 1, serves as a cultural bridge to the region's indigenous roots.

The persistence of the caña con ruda ritual highlights the enduring influence of syncretic beliefs in Argentina, where pre-Columbian indigenous traditions blend with colonial customs. By linking health and luck to the lunar and seasonal calendar, the practice reinforces a collective cultural identity rooted in the relationship between humans and the natural environment.
