Generally, when you notice medical information online, it’s probably best to approach it with caution. “If there is a promise of a miracle cure, that should ring alarm bells big time,” Gorfinkel said. “A lot of complex problems, including depression, anxiety, hair loss, acne; a lot of these problems are actually complicated, and they don’t have one single solution. This is especially true when things promise very quick answers, and often at a price.”

It’s always a good idea to run these ideas by either your family doctor or a pharmacist before investing in them.
