Last month Katlyn, a Massachusetts mother of a 2-year-old daughter, posted a worrying message in a private Facebook group that promotes and sells a dietary supplement that its members believe is a cure for a wide range of ailments, with group members claiming it can help everything from cancer to autism.
“I started my 2 yo daughter on both the drops and the spray on Sunday,” Katlyn wrote. “Monday morning she had a pretty painful looking white head above her top lip which I didn’t think much of until the next day she had another one on the side of her middle finger. She’s never had anything like this before.
