Can’t sleep?Try lettuce water. The latest trend sweeping TikTok is drinking lettuce water to help with insomnia. Seems you boil some lettuce leaves and then drink the water – and it’s supposed to make you sleepy. Can it be true? Maybe. According to Dr. Christopher Winter, of Charlottesville Neurology and Sleep Medicine and author of the book,The Sleep Solution: Why Your Sleep Is Broken and How to Fix It, lettuce contains something called lactucarium, which can make you feel drowsy. Lactucarium is that milky substance you see at the base of some types of lettuce – like romaine.
"It has a similar structure to opium, and has some sedative properties," Dr. Winter says. That said, you would need a “tremendous” amount of lettuce to get the effects, according to the doctor. "The amount of lactucarium you're getting from four to five lettuce leaves is unlikely to do much," he says. But he does say that the warmth of the water could help make you sleepy – not to mention the placebo effect. If you do decide to try it, the good news is that drinking the water of boiled lettuce isn’t harmful. (Health)
