Onion water is taking over TikTok. The drink has become increasingly popular on the video-sharing platform, with many users claiming it’s a natural cold and flu remedy that can help the body heal faster. TikTok user @earthenchild detailed how to make the drink in a now-viral video about onion water’s alleged healing properties and now doctors are weighing in. Dr. Kitty O’Hare, senior medical director for pediatrics at Duke Primary Care, said, “It has been around for a very long time, but there isn’t clear research showing that it has a benefit for your average person for coughs, colds and flus.” Dr. Jason Nagata, assistant professor of pediatrics at the University of California, San Francisco, agrees and said, “I’m not aware of any scientifically proven studies that show any kind of benefit for colds or respiratory symptoms. I just don’t think that people should expect that they’ll be able to really improve colds or flus with just onions.” Onion water is made by cutting up raw onions into small pieces then placing the chopped onions into a jar or bowl and adding filtered water. The fresh onion and water mixture should then sit covered in the refrigerator overnight or for about 12 hours, and then it's ready to drink.
