A doctor has issued a warning over a bizarre trend of using a potato to relieve symptoms of cold and flu.
The trick involves putting raw potatoes under your feet and people are saying the root vegetable has the ability to "draw out the cold" from a person's body, leaving them feeling energised. The "potato sock" trend has gone viral on TikTok, with various people trying it out for themselves – and some claim it works.
The hack involves slicing a raw potato and putting it under your feet using a sock to hold it in place. According to those who believe it works, it changes colour, showing that it has drawn out the cold from the body.
