Still, I sometimes find myself wishing that there was a way to stamp warnings on other people's pins. I'd slap "Caution: Does Not Work" signs on that stupid pin that suggests you can use Parmesan cheese container caps on canning jars (I have yet to find a brand for which this is actually true). "Requires Artistic Talent" should go on about half of the DIY wreaths, furniture painting tutorials, and party food posts. Most importantly, however, the nutritionist in me is convinced that there needs to be a "Not Necessarily/Highly Conditional" warning tag on so many of the DIY "miracle cure" style posts that circulate among the nutrition, holistic health, and herbalism themed boards. (Actually, it might be really fun to have a "Danger, Will Robinson!" sign to stick onto things that are really, truly ludicrous, too...)
My sister is a nurse, and recently sent me a pin for something called "Sleepy Dust." She wanted to know if it jived with what my (holistic/whole foods) nutrition books say, since it definitely didn't match up with what her medical books and experience tell her.
According to the pin (and blog post it's linked to), "Sleepy Dust" is a combination of sugar and salt that you can keep beside your bed and stick on your tongue before bed or when you wake up in the middle of the night to help you get to sleep (or back to sleep). The author of the post explains why she thinks this works, and raves about how awesomely it has worked for her.
Then there's the reality that historically, people didn't necessarily sleep through the night. In pre- industrial eras, it was common for people to wake up in the middle of the night for an hour or two. Records demonstrate that people were accustomed to using the time to meditate, pray, or snuggle with their spouse, and then consistently fell asleep again until morning. So what looks like insomnia to modern eyes, so indoctrinated by corporate schedules, is not necessarily an unnatural or inappropriate sleep cycle.
Finally, the human body technically never needs straight sugar (beyond what you would get in a primal-style high fat, lean protein, and fibrous veggie diet). You also can't just "get rid of" or "turn off" stress hormones - they have to be physically processed and released/removed from your system.
Although I am eternally grateful to live in an era in which so much wisdom and so many creative solutions are available to us with only the clicking of computer keys and the magic of Google, it is critical to remember that humans are biochemically and environmentally unique. Your body and your environment are not necessarily the same as the those of the person/expert/resource first to pop up on your screen. This is particularly true when pursuing secondary sites like Pinterest, where you can't really gauge the quality of information until you've gone to the source and done some digging. If something sounds too good to be true, it probably is, and just because it worked for someone else doesn't mean it's right for you. Look, experiment, and enjoy, but remember that on the interwebs, as in ancient Rome, Caveat Emptor applies - it's your responsibility to be aware and do the fact checking necessary to make sure the solutions, tips, and tricks you find are actually safe and scientifically sound!!
