    Editorial board



The International Journal of Clinical Aromatherapy was launched in response to the demands of practitioners working with essential oils in healthcare and related professions.

These therapists often use a range of application methods, styles and doses that may differ from the more traditional styles such as aromatherapy massage.
Healthcare professionals also require a source of evidence based information in order to successfully integrate clinical aromatherapy within orthodox practice.

The IJCA meets the needs of therapists by presenting solid practitioner-orientated and evidence-based information in a professional format.
Unlike any other aromatherapy journal currently available, each issue has a specific theme, with the majority of articles therein contributing valuable information concerning the chosen topic. Two issues are published per year.

All articles are peer reviewed and referenced where possible.
Members of the editorial board are all highly experienced in the essential oil field.


In 2014, the IJCA celebrated its 10th year as the leading clinical aromatherapy journal worldwide!

We are delighted to announce that Gabriel Mojay has taken on the role of Associate Editor, working alongside Editor Rhiannon Lewis.

Additionally we have expanded our editorial board.

The IJCA has now transitioned to an e-journal and has a new look and new format whilst retaining its highly relevant and professional content!

Obtain your copy of the special double edition for 2014 with its theme of “diversity in clinical applications” here!

The e-journal format gives you multiple advantages as a subscriber and will ultimately facilitate greater interaction between subscribers and practitioners.
From 2014 onwards all current and future issues will be online only with the option of also downloading individual articles and/or the complete volume/s.
All back issues prior to 2013 remain available in hard copy and can be ordered online here
