Serotonin is a hormone that acts as a neurotransmitter that relays messages from one part of the brain to another. It is found in the body's pineal gland, blood platelets, the digestive tract and the brain. Because of its role in the brain's ability to relay messages, serotonin is believed to have an impact in many of the body's physical and psychological functions. Notably, an imbalance of serotonin levels is believed to cause depression, anxiety, panic and obsessive-compulsive disorder. Although known for its neurotransmitter properties, approximately 90 percent of the body's serotonin is located in the digestive tract. Therefore, a diet high in foods that naturally boost serotonin may have positive effects for individuals suffering from a serotonin imbalance.

Bio-identical is a term used to describe hormones that are made in the laboratory and have the same molecular structures as the hormones made by a woman's own body. The hormones are derived from plants. Bio-identical hormones should not be confused with synthetic hormones that are made from the urine of pregnant mares. Drug companies can't patent a bio-identical structure, so they invented hormones that are patentable. Premarin, Provera and Prempro are synthetic hormones. They have been shown to increase the risks of cancer, heart disease, thyroid dysfunction and blood-clotting disorders.

Pheromones are chemicals that animals and humans give off as a bodily reaction. Other bodies pick these pheromones up as signals and react to them subconsciously. Humans cannot just create these pheromones within a lab as they can only truly be created within the cells of the body, but combining different chemicals that appeal to certain parts of the brain has been a profession for scientists for several decades. There are some methods where you can extract natural hormones from the human body with lab work, but this can be lengthy and expensive. With a few, you can create a perfume or cologne that works for your body, and add synthetic hormones if you desire.
