When i was 15 yo (1996), i was extremely sick. I spiked a fever of 104 degrees. My mother mixed lard & baking soda together, smothered it on my feet & put a 1 gallon freezer zip lock bag on each foot. This was to keep the nasty stuff from getting on my sheets. I truly thought she was nuts! I fell asleep & woke up 2 hrs later to my sheets being completely soaked from the fever breaking. She told me that my great grandmother told her about this remedy when she was a kid. And that was the first time she tried it.
