The 'Big Bang Theory' star is the latest celebrity to join the trend.
Kaley Cuoco is all about cupping.
The Big Bang Theory star took to Instagram on Thursday to reveal that she's tried the health trend -- and she liked it.

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."
