Chocolate contains very little caffeine, theobromine, serotonin, and phenylethylamin. Caffeine and theobromine are both considered alkaloids (or methylxanthines). Phenylethylamin is an anti-depressive and anti-stress agent. Serotonin is a hormone which is also produced naturally by the brain.

Who could resist the gift of chocolate? Perhaps someone who doesn't like chocolate (they're out there, ya know!). But chocolate gifts are perfect for the chocoholics on your list. There's literally something for everyone!
