I actually interviewed my mother because I’ve honestly never thought that some of the things we do may be considered folklore. I remember in class we talked about remedies and in my family if someone has a fever then we put onions on their feet. Specifically purple onions that are cut in half. The onion halves go on the soles of your feet and “pull out” the heat from you. She says that my grandma (her mother) would do that with them as children so she has continued the tradition.
Now, I have been on the receiving end on this and admittedly I am skeptical. I feel like it has worked to bring my fever down, but at the same time we used rags that are wet with the onions so I’m not sure if it’s the rags or the onions (my guess is it’s the rags). Nonetheless, I continue to do it because it’s tradition.
