A video is going viral on TikTok with this flu "remedy": You put slices of potatoes on the bottom of your feet before you sleep, wear socks to hold them in place and then take them off when you wake up. A video is going viral online, where a woman shares a flu "remedy." There will be an indentation on your feet, which she says is "normal." And the potato slices will be a "disgustingly dark" color, because "the toxins are removed." She insists you'll feel much better. Obviously, this is not backed by any medical professionals.
