People on Tik Tok peddling these scams

I don't see how this is legal, but people on Tik Tok peddling miracle "medicine" are becoming more common every day. No FDA approval, no research. Just their marketing hype and false promises. This one, lady is showing some sort of probiotic and claiming it can help people suffering from severe acid reflux and gastrointestinal reflux disease or GERD, replacing medicine that has been tested for decades.
