Cuoco is just the latest celeb to try the trend. Lea Michele had her first cupping session last week, and Kim Kardashian West tried the treatment in August, after being inspired by Olympic swimmer Michael Phelps.
And, of course, Gwyneth Paltrow was the first to "introduce the world to cupping" in 2004.
"Anytime I do anything for a while, there's always a 'she's insane,'" the Iron Man star told Women's Health last year. "But then people catch on. So I almost can’t go to an acupuncturist now without them thanking me for introducing the world to cupping."
