How Does Aromatherapy Work in the Body

Aromatherapy is a form of holistic healing that has been practiced for centuries, harnessing the power of aromatic plants to promote physical and mental well-being. In this article, we will explore the intricacies of aromatherapy and delve into the question: how does aromatherapy work in the body?

Throughout history, humans have recognized the therapeutic benefits of scent. Ancient civilizations such as Egypt, Greece, and China were among the first to utilize aromatic plants for medicinal purposes. These early practices laid the foundation for what we now know as aromatherapy.

Aromatherapy involves using essential oils derived from various plant sources to evoke specific physiological and psychological responses. These oils are obtained through methods such as steam distillation or cold pressing, resulting in highly concentrated extracts that capture the essence and fragrance of the plants.

In order to understand how aromatherapy works in our bodies, it is important to explore our sense of smell. Our olfactory system plays a key role in detecting scents and transmitting signals to our brain, which then triggers emotional and physiological responses. This powerful connection between scent and our emotions is what forms the basis of aromatherapy’s impact on our well-being.

Throughout this article, we will examine how essential oils enter our body through absorption methods such as inhalation or topical application. We will also uncover the science behind the physiological effects of these aromatic compounds on our bodies.

By gaining a deeper understanding of aromatherapy’s historical use and its impact on our senses and physiology, we can begin to appreciate its potential benefits in improving both physical and mental health. So let’s embark on this aromatic journey together and discover how integrating aromatherapy into our daily lives can enhance overall well-being.

The Power of Scents

Our sense of smell is a powerful tool that can evoke emotions, trigger memories, and even influence our behavior. The process of smelling occurs when odor molecules stimulate the olfactory receptors in our noses, sending signals to the brain for interpretation. This complex system allows us to perceive and differentiate between various scents, playing an integral role in our daily lives.

The Physiology of Smell

When we inhale a scent, odor molecules travel through our nasal passages and come into contact with the olfactory receptors located within the lining of the nose. These receptors are specialized nerve cells that recognize specific odor molecules. When stimulated by these molecules, they send electrical signals to the olfactory bulb, which is responsible for processing smells.

The Limbic System and Emotional Response

Once the olfactory bulb receives the electrical signals from the olfactory receptors, it relays this information to several areas in the brain including the limbic system. The limbic system is associated with memory, emotions, and motivation. This connection between scent and emotion explains why certain smells can trigger strong emotional responses or bring back vivid memories.

Research has shown that certain scents like lavender can promote relaxation and reduce anxiety levels due to their effects on the limbic system. On the other hand, citrus scents such as lemon or orange may enhance mood and increase alertness. Understanding these connections between scent and emotion can be harnessed through aromatherapy to achieve specific mental or emotional states.

Behavioral Effects of Scents

Apart from influencing emotions, scents can also impact our behavior. For example, studies have shown that certain smells can affect appetite and cravings. In one study published in the journal Chemical Senses, researchers found that individuals who were exposed to a pleasant aroma had reduced cravings for sweet foods compared to those exposed to an unpleasant scent.

Additionally, research has indicated that certain scents can enhance cognitive function and improve focus. For instance, the scent of rosemary has been found to enhance memory performance, while peppermint has been shown to increase alertness and overall cognitive performance.

Essential Oils

Essential oils are highly concentrated plant extracts that capture the natural aroma and beneficial properties of plants. These oils are typically obtained through a process called steam distillation, where steam is passed through the plant material to separate the volatile compounds. After condensation, the essential oil is separated from the water, resulting in a potent and aromatic liquid.

Another method commonly used to extract essential oils is cold-press extraction, which is primarily used for obtaining oils from citrus fruits such as oranges, lemons, and grapefruits. In this method, mechanical pressure is applied to the fruit peel to release the essential oil. This technique allows for a greater yield of oil with minimal alteration to its chemical composition.

It’s important to note that not all plant materials can produce essential oils. Certain plants have specialized structures, such as resin glands or glandular hairs, which contain these valuable compounds. Examples of such plants include lavender, peppermint, eucalyptus, and tea tree. These plants have been recognized for their therapeutic properties for centuries and continue to be widely used in aromatherapy practices today.

To summarize, essential oils are highly concentrated plant extracts obtained through methods like steam distillation or cold-press extraction. These natural substances contain aromatic compounds that contribute to their distinct scents and therapeutic benefits. By harnessing the power of these essential oils, aromatherapy aims to enhance physical and mental well-being through their myriad of healing properties.

Absorption Methods


One of the most common methods of absorption in aromatherapy is inhalation. When we inhale, the molecules from essential oils are carried into the nasal cavity where they stimulate the olfactory system. These molecules then bind to receptors on nerve cells and send signals to the brain, specifically to areas associated with emotions and memory. This is why certain scents can trigger feelings of happiness or relaxation.

Inhalation can occur through several different techniques. One popular method is using an essential oil diffuser, which disperses a fine mist of oil particles into the air for inhalation.

Evidence Based Birth Aromatherapy

Another option is adding a few drops of essential oil to a bowl of hot water and inhaling the steam by placing a towel over your head and leaning over the bowl. Alternatively, you can simply inhale directly from the bottle or apply a drop of oil onto a tissue or cotton ball and hold it close to your nose.

Topical Application

Another way that aromatherapy enters the body is through topical application. When applied directly to the skin, essential oils can be absorbed into the bloodstream through hair follicles, sweat glands, and cell membranes. From there, they are circulated throughout the body.

Before applying essential oils topically, it is important to dilute them in a carrier oil such as jojoba oil or almond oil to prevent skin irritation. The mixture can then be massaged onto different areas of the body depending on your specific needs. For example, lavender oil may be applied to temples for headache relief or peppermint oil can be rubbed onto sore muscles for pain relief.

Ingestion (Oral Intake)

While less common than inhalation or topical application, ingestion is another method by which aromatherapy can enter the body. However, this method should only be used under the guidance of a qualified professional as certain essential oils can be toxic if ingested improperly. It is important to note that not all essential oils are safe for internal use.

To ingest essential oils, they can be added to a beverage or used in cooking. For example, adding a drop of lemon essential oil to a glass of water can provide a refreshing taste and potential health benefits. It is crucial to follow proper dosage guidelines and consult with a healthcare professional before using any essential oil internally.

By understanding the various absorption methods of aromatherapy, individuals can choose the most effective way to experience its benefits. Whether through inhalation, topical application, or even ingestion under proper guidance, aromatherapy has the potential to positively impact both physical and mental well-being.

The Science Behind It

Aromatherapy is not just about pleasant scents and relaxation; there is also a scientific basis behind its physiological effects on the body. When we inhale essential oils, odor molecules travel through the nose and interact with sensory receptors in our olfactory system. These receptors are connected to the limbic system in the brain, which plays a crucial role in regulating emotions, memory, and behavior.

Research has shown that different scents can have varying effects on our mood and physiology. For example, lavender essential oil is known for its calming properties and can help reduce anxiety and promote better sleep. On the other hand, citrus oils like lemon or orange can have an energizing effect and enhance focus and concentration.

The physiological effects of aromatherapy extend beyond just the olfactory system. Inhaling essential oils can also affect other systems in the body, such as the respiratory system. Certain oils, like eucalyptus or peppermint, can help relieve congestion and improve breathing. Additionally, some studies have suggested that aromatherapy may influence the immune system by promoting a balanced immune response.
