Across four 90-minute lectures, we will move progressively from understanding the respiratory terrain to exploring the pharmacological actions of essential oils, examining how route of administration influences therapeutic outcomes, and finally bringing these elements together through practical formulations and clinical reasoning.

Lecture 1 – November 4th
Understanding the Respiratory Sphere and its Challenges

Rhiannon says “Before choosing the oil, understand the terrain”.

The respiratory tract is not simply a series of airways. It is a highly specialised interface between the external environment and the internal body, equipped with sophisticated mechanisms of filtration, immune defence, mucus production, clearance and repair.

In this opening lecture we establish the clinical foundations needed for intelligent aromatic intervention. We will revisit relevant respiratory anatomy and physiology and examine what changes when normal respiratory function is disrupted.

From upper respiratory infections and excessive secretions to inflammation, bronchial hyperresponsiveness, persistent cough and chronic respiratory disease, we will consider the different therapeutic challenges presented by the respiratory sphere – and importantly, recognise where aromatherapy may contribute, where its limitations lie, and when referral or conventional medical management takes priority.

The clinical question: What is happening – and where might aromatic intervention realistically help?

Lecture 2 – November 11th

Respiratory Actions of Essential Oils and Related Products

Rhiannon says “Moving beyond ‘respiratory oils’ towards therapeutic actions”.

Why do some aromatic molecules influence mucus and expectoration while others affect airway sensation, inflammation, microbial activity or breathing comfort?

This lecture explores the principal actions that make essential oils and related aromatic products relevant to respiratory care. We will examine the evidence behind commonly cited actions such as antimicrobial, anti-inflammatory, mucolytic, expectorant, antitussive and bronchodilatory effects, while distinguishing between traditional use, experimental evidence and clinically demonstrated effects.

Particular attention will be given to key aromatic molecules and their mechanisms, while also considering the importance of the whole essential oil and the potential contribution of hydrolats and other aromatic preparations.

The aim is not to memorise another list of essential oils, but to develop the ability to match aromatic properties with a clearly identified therapeutic objective.

The clinical question: What action do I need – and which aromatic intervention can reasonably provide it?

Lecture 3 – November 18th

Routes of Administration for the Respiratory Sphere

Rhiannon says “The right essential oil is only part of the intervention. How we deliver it matters”.

Inhalation may appear to be the obvious route for respiratory aromatherapy, but other routes occupy an important supportive place in care.

We will examine all the relevant routes of administration and consider what happens between the bottle and the respiratory tract: volatility, dose, duration of exposure, local versus systemic effects, patient acceptability and the practical realities of using aromatic interventions safely.

Special consideration will be given to vulnerable populations and situations where apparently simple methods of administration may not be appropriate.

The clinical question: How can I deliver the intervention safely and effectively to the place where it is needed?

Lecture 4 – November 25th

Putting it all Together: From Clinical Reasoning to Formulation

Rhiannon says “From knowledge to therapeutic decision-making”.

The final lecture brings the course together through practical examples covering a range of acute and chronic respiratory challenges.

Rather than beginning with a recipe, each example will begin with the person and the therapeutic problem. We will identify the principal clinical objectives, determine appropriate aromatic actions, select essential oils or related products, choose the most suitable route of administration and develop a formulation with a clear rationale.

Examples will demonstrate how apparently similar respiratory complaints may require very different approaches – and how formulations can be adapted according to age, vulnerability, symptom presentation, stage of illness and therapeutic priorities.

Participants will leave with practical formulation strategies, but more importantly with a framework for constructing their own rational respiratory interventions.

The clinical question: How do I translate assessment, evidence and aromatic knowledge into an appropriate intervention?
