Aromatherapy: Benefits, How It Works and What to Expect

What Is Aromatherapy?

Aromatherapy is a therapeutic practice that uses essential oils, concentrated extracts obtained from flowers, leaves, roots, bark and other plant materials, to promote health and wellbeing. Although the use of aromatic plants for therapeutic purposes is an ancient practice present across cultures including Egyptian, Chinese, Indian and Graeco-Roman civilisations, modern aromatherapy was formalised by French chemist René-Maurice Gattefossé in the early twentieth century, after he accidentally discovered the wound-healing properties of lavender essential oil.

Essential oils are highly concentrated substances that capture the chemical and aromatic essence of each plant. Each oil has a unique chemical profile composed of dozens or hundreds of bioactive compounds, including terpenes, esters, alcohols and phenols, which are believed to contribute to its therapeutic effects.

Aromatherapy can be applied in several ways: direct or diffused inhalation, topical application diluted in a carrier oil, addition to baths or compresses, or incorporation into massage sessions. Each method of application has distinct characteristics and benefits.

It is important to emphasise that aromatherapy is a complementary therapy, it does not replace medical treatment. However, it can be a powerful ally in supporting general wellbeing, stress management and quality of life.

In Portugal, aromatherapy has been growing steadily in popularity, and at Marcar Terapias you can find specialist aromatherapists throughout the country.

How Does Aromatherapy Work?

The mechanisms by which essential oils may produce effects in the body are multiple and have been the subject of increasing scientific research:

Olfactory pathway: When you inhale an essential oil, aromatic molecules activate olfactory receptors in the nose, which send direct signals to the limbic system, the region of the brain associated with emotions, memory and stress response. This is one of the fastest and most direct pathways for influencing emotional and mental states. Some studies suggest that certain aromas, such as lavender, may help reduce anxiety and promote relaxation.

Transdermal absorption: When applied topically, always diluted in a carrier oil, the bioactive compounds in essential oils can be absorbed through the skin and enter the bloodstream, potentially exerting systemic effects. The effectiveness of this route depends on factors such as molecular size, application area and the integrity of the skin barrier.

Pharmacodynamic activity: Some compounds found in essential oils have demonstrated, in laboratory studies, antimicrobial, anti-inflammatory, antioxidant and other biological activities. It is important to note that these studies have often been conducted in vitro, and results do not always translate directly into equivalent clinical effects in humans.

In a professional aromatherapy session, the therapist carries out a detailed assessment of the client's needs and preferences before selecting and blending the most appropriate oils, creating a personalised formulation for each individual.

Benefits of Aromatherapy

Scientific research on aromatherapy has grown considerably over recent decades, and several studies suggest this therapy may offer genuine benefits:

Stress and anxiety reduction: This is arguably the most studied and documented benefit of aromatherapy. Some studies suggest that inhaling oils such as lavender, bergamot and ylang-ylang may help reduce physiological stress markers, including heart rate and blood pressure, promoting a deeper state of relaxation.

Improved sleep quality: Oils such as lavender and Roman chamomile have been associated in some studies with improvements in sleep quality, reduced time to fall asleep and a greater sense of rest upon waking.

Relief from headaches and migraines: Topical application of peppermint essential oil to the temples may help alleviate tension headaches, according to some studies. Inhalation of certain oils may also be helpful for some individuals.

Emotional support and mental wellbeing: Aromatherapy may help manage difficult emotional states such as sadness, irritability or lack of motivation. Oils including bergamot, neroli and rose have been associated with positive effects on mood and emotional resilience.

Muscular pain relief: Massage using diluted essential oils, such as eucalyptus, rosemary or ginger, may help relieve muscular pain and tension, particularly when combined with effective massage techniques.

Respiratory support: Oils such as eucalyptus, ravintsara and tea tree may help promote respiratory comfort in situations involving congestion or upper airway discomfort, though they do not replace medical treatment for specific respiratory conditions.

It is essential to remember that aromatherapy does not replace medical diagnosis and treatment. Essential oils are potent substances that must be used with knowledge and respect for their properties.

Who Is Aromatherapy For?

Aromatherapy is a versatile therapy with applications for a wide variety of people:

People with chronic stress or burnout: Aromatherapy can be a highly effective self-care tool for those living under constant pressure, helping to create moments of genuine relaxation and develop a more balanced relationship with stress.

Those with sleep difficulties: For people struggling with insomnia or poor sleep quality, aromatherapy, particularly inhaling sedative oils such as lavender before bedtime, can form part of an effective sleep hygiene routine.

People going through emotionally difficult periods: Aromatherapy can be a valuable complement to psychological or emotional support during periods of grief, life transition or emotional difficulty.

Those suffering from muscular pain or tension: The combination of massage with appropriate essential oils is particularly effective for relieving accumulated muscular tension and physical discomfort.

Pregnant women: Some forms of aromatherapy may be beneficial during pregnancy for relieving nausea, oedema or anxiety. However, many essential oils are contraindicated during pregnancy, medical approval and working with an aromatherapist experienced in maternal health are absolutely essential before proceeding.

People in palliative care: Aromatherapy has been increasingly integrated into palliative care settings to support comfort, quality of life and the emotional wellbeing of patients and their families.

Important safety note: essential oils should never be ingested without specialist supervision, and some are contraindicated in people with epilepsy, liver conditions, allergies to certain plants or in young children. Always consult a qualified aromatherapist and your doctor.

What to Expect from an Aromatherapy Session

A professional aromatherapy session is a personalised and sensory experience. Here is what you can typically expect:

Detailed initial consultation: The aromatherapist will begin with a comprehensive consultation covering your health status, medical history, current medications, session goals, aromatic preferences and any known allergies. This assessment is essential for creating a safe and effective formulation.

Oil selection and blending: Based on the consultation, the therapist will select and combine the essential oils most suited to your needs, diluting them to a safe concentration in a vegetable carrier oil such as jojoba, sweet almond or fractionated coconut oil.

The session itself: Aromatherapy may be applied in various ways, through massage (the most common combination in professional settings), environmental diffusion, direct inhalation, compresses or aromatic baths. Aromatherapy massage combines the benefits of therapeutic touch with the properties of the oils, amplifying the relaxation effects.

Duration: A complete aromatherapy session typically lasts between 60 to 90 minutes, including the initial consultation. Sessions focused on specific areas or maintenance appointments may be shorter.

After the session: It is normal to feel a deep sense of relaxation after the session. The therapist may recommend specific products to continue the benefits at home. Drinking water and avoiding direct sun exposure on treated areas, particularly with citrus oils, is generally advised.

Ongoing care: For specific conditions or long-term wellbeing goals, a series of regular sessions is generally more effective than isolated appointments.

How to Find a Good Aromatherapist

The therapist's qualifications are crucial for a safe and effective experience. Consider these criteria when searching in Portugal:

Specific, certified training: Aromatherapy requires specialist training in the phytochemistry of essential oils, safe usage, contraindications and application techniques. Verify the therapist's qualifications and whether they hold training recognised by professional associations in the field.

Safety knowledge: A good aromatherapist should have thorough knowledge of drug interactions, contraindications and safe dilution ratios. Do not hesitate to ask about their approach to safety before booking your appointment.

Reviews and recommendations: Reading other clients' experiences is always valuable. At Marcar Terapias, you can access Google reviews from real clients, making it much easier to choose a trustworthy aromatherapist anywhere in Portugal.

Oil quality: Therapeutic-grade essential oils that are 100% pure and from reliable sources make a significant difference to results. A good therapist should be transparent about the brands and suppliers they use.

Session personalisation: A competent therapist does not apply a standard formula to every client, each session should be adapted to the individual needs and circumstances of each person.
