St John’s Wort (Hypericum perforatum extract) is a weak inhibitor of monoamine oxidase (MAO), which destroys monoamine neurotransmitters including in the brain and leads to low spirits. St. John’s Wort has also been shown to inhibit reuptake of several neurotransmitters, such as serotonin, dopamine, noradrenaline, and GABA in the brain, and to reduce expression of interleukin-6. Each of these actions can contribute to alleviating low mood status by slowing the recycling of neurotransmitters needed for maintaining emotional balance. Flavonoids, hypericin and pseudo-hypericin, are the constituents thought to be associated with the benefits of St John’s Wort. In particular, hypericin appears to be the main active ingredient.
