Chocolate wasn't always synonymous with Valentine's Day. The first box of chocolates specifically designed for Valentine's Day was created by Richard Cadbury in the 1880s. However, throughout the 19th century, doctors told lovesick patients that they should eat chocolate to help mend their broken hearts. Additionally, chocolate has a long history as an aphrodisiac. Casanova ate chocolate with his lovers, as did Madame DuBarry, courtesan and mistress to Louis XV.
Recent research has found a reason for this: chocolate contains a compound know as phenylethylamine, the same chemical that the brain produces when you fall in love. You'd need to eat more chocolate that anyone could possibly consume to get that "fall in love" feeling from it, however.
