Use of black vulture (Coragyps atratus) in complementary and alternative therapies for cancer in Colombia: A qualitative study

BACKGROUND Although Coragyps atratus has been used as a traditional therapy for patients with cancer, the scientific literature does not contain enough information on how this therapy is used or the mechanisms that explain this therapeutic practice. OBJECTIVES To understand the methods of use and the reasons given by patients and caregivers for the use of Coragyps atratus in cancer treatment. METHODS This study used a qualitative design based on twenty in-depth interviews of patients with cancer or caregivers of patients with the disease. The analysis of the text was based on an inductive thematic approach. RESULTS Resistance to disease and immune enhancement are properties attributed to Coragyps atratus when used for cancer treatment. The most recommended method of use is fresh blood ingestion, and the associated mechanism of action is transfer of immune factors to the individual who consumes it. CONCLUSIONS Use of Coragyps atratus as a treatment for cancer is a popular alternative therapy in Colombia. More studies are needed to understand the clinical effects of this intervention in cancer patients.
