The Science Of Scents: How Fragrances Work

Fragrances have been used for hundreds of years, from the ancient Orient to the courts of European monarchs. The sense of smell is a right-brain activity, which rules emotions, memory, and creativity. Perfumes are made from thousands of scent molecules, and the precise formulae of commercial perfumes are kept secret. The way a fragrance interacts with the wearer's physiology can be influenced by factors such as diet, medication, and the dryness of the skin.

The sense of smell and its connection to emotions, memory, and creativity

The sense of smell is considered a right brain activity, which rules emotions, memory, and creativity. Smell is closely linked to memory and can trigger powerful emotional responses. For example, the scent of freshly baked cookies might remind someone of their grandmother's baking and make them feel comforted or nostalgic.

Smell can also influence our emotions and creativity. Certain fragrances can make us feel relaxed, energized, or even more creative. Aromatherapy, which involves smelling essential oils, is often used to enhance mood and well-being. The theory behind aromatherapy suggests that essential oils can help bolster the immune system and balance hormonal and body energy when inhaled or applied topically.

The connection between smell and emotions, memory, and creativity is so strong that it has been explored for centuries. Europeans discovered the healing properties of fragrance in the 17th century when doctors treating plague victims used strong scents to protect themselves from disease. Perfume then became popular among royalty, with France's King Louis XIV being nicknamed the "perfume king" due to his excessive use of fragrances.

Today, the fragrance industry continues to explore the potential of scent to heal, improve well-being, and enhance relationships. The precise formulae of commercial perfumes are often kept secret, but it is known that factors such as diet, medication use, and skin type can influence how a fragrance interacts with an individual's physiology and their perception of the scent.

The use of fragrances in aromatherapy

Aromatherapy is the practice of smelling oils and fragrances to cure physical and emotional problems. It is based on the theory that using essential oils helps to bolster the immune system when inhaled or applied topically. Aromatherapy can also be used as a form of psychotherapy, as smelling sweet smells can affect one's mood.

The sense of smell is considered a right-brain activity, which rules emotions, memory, and creativity. The use of fragrances in aromatherapy can, therefore, help to balance hormonal and body energy. For example, a person's diet can influence how a fragrance interacts with their physiology and the perception of the fragrance. Eating spicy and fatty foods can increase the intensity of a fragrance. Similarly, the use of medications can also impact the character of a fragrance. The relative dryness of skin is another factor that affects how long a fragrance will last, as dry skin will not hold a fragrance as long as skin with more oil.

The practice of using fragrances for their healing properties has a long history. During the 17th century, doctors treating plague victims covered their mouths and noses with leather pouches holding pungent cloves, cinnamon, and spices, which they believed would protect them from disease. Perfume then came into widespread use among the monarchy, with France's King Louis XIV being called the "perfume king".

The composition of perfumes and the placement of perfume on the body

The composition of perfumes is a closely guarded secret. Even if the ingredients were widely published, the formulae are so complex that they would be of little use to the general consumer. However, we do know that a variety of factors can influence how fragrance interacts with the wearer's physiology and affect the perception of the fragrance. For example, diet is one factor, as eating spicy and fatty foods can increase the intensity of a fragrance. The use of medications can also impact the character of a fragrance. The relative dryness of the wearer's skin is important, since dry skin will not hold fragrance as long as skin with more oil.

When it comes to the placement of perfume on the body, the best spots to apply perfume are the pulse points: the points that are warm and moist because your veins are closest to the skin. These include the inside of your wrists, inner elbows, below your belly button, behind your earlobes, the back of your knees, and your throat. These warm spots on your body emit extra body heat, which helps to naturally diffuse a scent. If you're wearing a low-cut top, you can also mist perfume over your chest area, and if you're wearing a cropped top, you might want to spritz your torso.

The influence of a wearer's physiology on the perception of fragrance

A variety of factors influence how fragrance interacts with the wearer's physiology and affect the perception of the scent. Diet is one factor, as eating spicy and fatty foods can increase the intensity of a fragrance. The use of medication can also impact the character of a fragrance. Dry skin will not hold fragrance as long as skin with more oil.

The sense of smell is considered a right-brain activity, which rules emotions, memory, and creativity. Smelling sweet smells also affects one's mood and can be used as a form of psychotherapy.

In the world of perfumery, how to apply a perfume is just as important as the composition of the notes themselves. The correct placement of your favourite eau de parfum depends entirely on the environment in which it's worn and the outfit for which it accessorises.

The history of perfume and its use in medicine

The use of perfume and fragrance has a long history, stretching back to ancient times. The world's first recorded perfume maker was a woman named Tapputi, who lived in ancient Babylon around 1200 BCE. She is also recognised as the world's first chemist. The history of scent is closely linked to Asian cultures, particularly ancient Indian and Chinese cultures.

The ancient Chinese and medieval Europeans believed that fragrance purified the air and prevented diseases. Ancient doctors would use perfumes medicinally to treat infections and even mental illness. The ancient Greeks also discussed perfumery, with Theophrastos, Pliny the Elder, and Dioskourides all writing about it.

Muslims in Middle Eastern countries, especially Egypt, Persia (now Iran), and the Arabian Peninsula, made significant contributions to the improvement of natural perfumes and the use of natural essences in medicines. The famous Arab philosopher and physician Al-Kindi (c. 801-873) composed a book called *Book of the Chemistry of Perfume and Distillations*, which included over 100 recipes and methods for making perfumes, fragrant oils, and aromatic oils. A Persian Muslim chemist and physician, Abu Ali Ibn Sina (known as Avicenna in the West), invented the method for extracting oils from natural sources such as flowers through distillation, which is still the most common method of extraction today.

Perfume came to Europe when 13th-century Crusaders brought back samples from Palestine to England, France, and Italy. Europeans discovered the healing properties of fragrance in the 17th century, when doctors treating plague victims covered their mouths and noses with leather pouches containing pungent cloves, cinnamon, and spices, which they believed would protect them from disease. Perfume then came into widespread use among the monarchy, with France's King Louis XIV using it so much that he was called the "perfume king".

Today, the use of fragrance in medicine continues with aromatherapy, which involves smelling oils and fragrances to cure physical and emotional problems and balance hormonal and body energy.
