St. John's Wort is widely used in Europe to fight the blues. In Germany, it reportedly outsells Prozac seven to one.

This herb works by influencing levels of neurotransmitters in the brain thought to influence well-being, including dopamine and serotonin. It contains an active ingredient known as ''hypericin" which slows down the breakdown of these neuro-transmitters in the brain. In scientific terms, it's called a monoamine oxidase (MAO) inhibitor. It increases the half-life (the amount of time the neurotransmitters stay active in the brain), thus extending and enhancing their effects.
