ethno etiologies

Many cultures have ethno-etiologies that provide explanations for illness that are not based in science. From a biomedical perspective, the non-scientific medical treatments provided in these cultures have a low likelihood of success. Despite this, people tend to believe that the treatments are working.

• Why do you think people tend to be satisfied with the effectiveness of the treatments they receive that are based on the ethno-etiologies? 
• In transcultural nursing practice, why would it be important for nurses to understand such ethno-etiologies when nurses interact with patients of different cultures?
