It’s funny how we’ll casually buy a medication with a three-page side-effect list or spray a cleaner that says “use in a well-ventilated area while wearing gloves and possibly a hazmat suit” — no questions asked — but the moment someone mentions essential oils, suddenly we’re conducting a double-blind study, checking five medical journals, and calling a cousin who once took chemistry. Apparently, swallowing unpronounceable ingredients is fine, but a drop of lavender requires a PhD and a committee meeting.
