What Is Aromatherapy?

Aromatherapy is a holistic healing approach that utilises the natural fragrances of essential oils to promote physical, emotional, and mental well-being.

The practice of aromatherapy is based on the concept of using plant-derived essential oils to improve a person's health and mood. It has been used for centuries across various cultures, including ancient Egypt, China, and India.

Aromatherapy is believed to work by stimulating smell receptors in the nose, which then send messages through the nervous system to the limbic system - the part of the brain that controls emotions.

The use of essential oils in aromatherapy has gained popularity in alternative medicine and is often used in conjunction with massage therapy, meditation, and yoga for its calming and healing effects.

Mechanisms of Action and Effects on the Central Nervous System

Recent studies have shown that essential oils produce varying pharmacological responses in the nervous system, leading to anxiolytic, antidepressant, sedative, and anticonvulsant effects. These effects are believed to be due to the involvement of multiple neurotransmitter systems, resulting in measurable physiological changes in the brain. Clinical trials have further demonstrated the influence of essential oils on physiological parameters like blood pressure, heart rate, respiratory rate, brain wave composition, and cortisol serum levels, which correlate with psychological effects. These findings suggest a potential for developing essential oil-based treatments for mental illnesses such as depression, anxiety, and dementia​.


What Are Essential Oils?

Essential oils are concentrated, aromatic compounds extracted from plant materials through various methods such as distillation or cold pressing.

These oils are derived from a wide range of sources including flowers, herbs, fruits, and even tree bark, and they possess a myriad of therapeutic properties. The extraction process typically involves carefully selecting the plant material, then using steam or water to release the aromatic compounds.

Each oil carries the distinct essence of the plant it is derived from, and their unique chemical compositions contribute to their renowned healing and aromatic characteristics.

How is Aromatherapy Used?

Aromatherapy is applied through various methods including inhalation, topical application, and diffusion via devices like essential oil diffusers, as well as through massage therapy.

Inhalation is one of the most common methods, involving the direct inhalation of essential oils through the nose or mouth. This can be achieved by adding a few drops of essential oil to a bowl of hot water or using a personal inhaler.

Topical application involves diluting essential oils with a carrier oil and applying them to the skin through massage or direct application.

Diffusion, on the other hand, disperses the essential oils into the air using devices like ultrasonic diffusers or nebulisers, filling the room with delightful aromas.

Each of these methods offers unique benefits and can be tailored to suit individual preferences.

How to Use Essential Oils Safely?

Using essential oils safely involves practices such as dilution with carrier oils, conducting patch tests, and seeking professional guidance to ensure proper usage and minimise potential risks.

Dilution is a crucial step as it helps prevent skin irritation or sensitivity reactions. Patch testing, by applying a diluted oil to a small area of skin, allows you to check for adverse reactions before widespread use. It's also important to consult with a qualified aromatherapist or healthcare professional, especially when using essential oils for specific health conditions or if you're pregnant or nursing. By following these steps, you can enjoy the benefits of essential oils while prioritising safety.

Mix with Carrier Oils

Diluting essential oils with carrier oils is a critical safety practice that ensures proper application and minimises the risk of skin irritation or adverse reactions.

Carrier oils act as a buffer, decreasing the concentration of essential oils on the skin, which helps to prevent potential sensitivities or sensitisation. This dilution method also aids in extending the lifespan of the essential oil, allowing it to cover a larger skin surface area and be absorbed more effectively. By incorporating carrier oils, the essential oils can be evenly spread on the skin, promoting a more balanced and gentle topical application, enhancing the overall efficacy and safety of the essential oil usage.

Carry out a Patch Test

Conducting a patch test before using essential oils helps to assess skin sensitivity and reduces the risk of allergic reactions, serving as a crucial safety measure.

This simple yet essential step can prevent potential adverse effects, especially when using potent essential oils. By applying a diluted oil to a small area of skin, individuals can observe any adverse reactions, such as redness, itching, or irritation. It's important to wait at least 24 hours before fully using the oil to ensure that no delayed sensitivity or allergic responses occur. Patch testing is an indispensable practice, especially for those new to using essential oils or when trying a new oil for the first time.

Refrain from consuming essential oils

Whilst essential oils are commonly used in aromatherapy and topical applications, their ingestion can pose serious risks. Ingesting essential oils can irritate the gastrointestinal tract, cause allergic reactions, and even lead to organ damage. It's important to exercise caution and seek advice from a qualified healthcare professional before using essential oils. Safety measures, such as proper dilution and patch testing, should be followed to minimise the likelihood of adverse effects. Respecting the potency of essential oils and using them as intended will promote their safe and effective utilisation.

Seek advice from a professional

Seeking guidance from a professional, such as aromatherapy practitioners or healthcare experts, is advisable when incorporating essential oils into wellness and therapeutic practices to ensure safe and appropriate usage.

These professionals possess valuable expertise in understanding the complexities of essential oils, including their properties, potential interactions, and appropriate dilution methods. By consulting with them, individuals can gain insights into personalised usage guidelines that align with their specific health needs, ultimately maximising the benefits of aromatherapy while minimising the risk of adverse reactions.

Professionals can offer tailored recommendations for selecting high-quality essential oils from reputable sources, further ensuring the efficacy and safety of incorporating these natural remedies into daily routines.
