As a scientist I try to apply a scientific mindset to most aspects of my life (well, except when it comes to matters of the heart, but that's a story for another day...). Which is why anything labeled "alternative" or "holistic" raises red flags for me until I see some good research* that turns the flags from red to yellow, and, in rare cases, green. 

My partner is also a scientist, a particle physicist who approaches everything with a scientific mindset (including matters of the heart, but that's a story for yet another day haha:)). So imagine my surprise when, about a year into dating, when an especially insidious flu was decimating Southern California, he said we should try this "natural remedy" that a hippie friend of his mom had taught him. But the real shocker came when it worked. And kept working. I call it Magic Hippie Potion.
