    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.


The IJCA is currently undergoing transition to become an e-journal. This gives you multiple advantages as a subscriber.
From 2013 onwards all current and future issues will be online only with the option of downloading individual articles and/or the complete volume/s.
All back issues remain available in hard copy and can be ordered online here
