Ah, chocolate. Despite its bitter taste, we love it dearly. Perhaps this has something to do with the serotonin and dopamine released into our brains when we eat it. Chocolate has many psychoactive chemicals: sugar, caffeine, anandamide (the bliss chemical), tryptophan, and the favored symbol of chocolate: theobromine. Theobromine is a mild stimulant related to caffeine that makes up about 2% of cacao beans. It's thought to elevate mood. The name theobromine is derived from Greek words, meaning "food of the gods." I would have to agree. Especially when mixed with spicy chili, the way the Mayans enjoyed it 2,600 years ago. For the health benefits from the flavonoids and antioxidants in chocolate, choose the darkest varieties.

It closes with a lobster clasp.Made With Molecules offers original, handmade, high quality jewelry by scientist-turned-artist Raven Hanna, PhD.
