That's surprising. I never ate much of the fruit but I know some relatives that make juices out of it. They have to use large amounts for that so maybe they're really drinking poison!
Just saw the video, its no joke. The research concludes that people with some diseases can even experience death! You need to know your medical issues before even touching this fruit or don't even touch it at all.
Honestly, I can't even imagine how this fruit became so popular with how great the potential risks of eating star fruit or drinking star fruist juice is. It's actually really scary, even more so since liver and kidney issues are far from uncommon in this day and age.
