Serotonin is a neurotransmitter or communicator transmitting electrical impulses from one nerve to another. It is produced in the brain and intestinal tract and is responsible for important functions of behavior, such as the ability to plan and make decisions from a higher perspective. It is thought that serotonin deficiency is responsible for depression, obsessive compulsive disorders, addictions, and even suicide. Recent studies have shown that serotonin is effective in the experience of love, giving and maintain healthy relationships, and also combat the negative effects of dopamine, a substance always connected to the craving of addiction, and is present whenever the body experiences tenderness. Serotonin is not only the metabolic precursor of melatonin, a hormone produced by the pineal gland, and therefore useful in spiritual stimulated activity of the pineal gland, but also serves as a precursor to the greater production of endogenous DMT.
