Things I have recently listened to people proclaim the health benefits of in person or on facebook.
Raisins soaked in Gin for arthritis
A combination of Cinnamon and Honey
Strawberries for teeth whitening
A combination of lemon, ginger, garlic, honey, pineapple, and cayenne in lieu of a flu shot
WD-40 also for arthritis
Obviously some of these are less bunk than others, and most won't hurt you as long as you don't take them in lieu of treatments you've been prescribed (with the notable exception of spraying yourself with WD-40).
However, I'd really just like to see someone I know post a long missive or an infographic about the amazing health benefits of broccoli.
