The word "aromatherapist" can sound like a regulated health profession. The sources we read describe something looser. This page explains what they say about training, certification and licensing, and how to read the titles you may see. It does not rank schools or associations.
- In the US and UK, no license is required to practice aromatherapy. The National Cancer Institute (NCI) cancer information summary says training and certification for lay practitioners are available at several schools in both countries, but there is no professional standardization in the US and no license is required in either country. [1] The summary lists its latest update as October 31, 2024. [1]
- There is no single national system for credentials in complementary health. NIH's National Center for Complementary and Integrative Health (NCCIH) says state governments decide what credentials practitioners need, and these vary widely by state and by discipline. [2]
- Titles are not defined in the sources we read. We looked for definitions of "certified", "clinical" and "registered" aromatherapist in NCCIH and NCI pages and in PubMed and Europe PMC records on aromatherapist training and regulation, and found none. For those titles: Proper evidence not found.
How the sources define the terms
| Term | What NCCIH says |
|---|---|
| Credentials | A broad term that can refer to a practitioner's license, certification or education. [2] |
| License | In the United States, government agencies grant and monitor licenses. [2] |
| Certification | Professional organizations certify practitioners, and certification can be a prerequisite for licensure or, in some cases, an alternative. [2] |
| State approaches | Mandatory licensure, title licensure (credentials needed before using a title) and registration (giving a state agency information about training and experience). [2] |
| A caution | Being licensed or certified is not always a guarantee of being qualified. [2] |
What training exists, as the sources describe it
United States and Canada. The NCI summary says certificate programs exist, some approved by the National Association for Holistic Aromatherapy (NAHA), and that NAHA and the Alliance of International Aromatherapists are the two governing bodies for national educational standards. It says NAHA was taking steps toward standardizing certification, and that the Canadian Federation of Aromatherapists has set standards for certification in Canada. [1] We name these only because the NCI summary does. We did not check their current status or compare programs, and a mention here is not an endorsement.
Health professionals. The same summary says specific courses for licensed health professionals now give nursing or continuing medical education credit hours. [1] It adds that nurses have tended to be the main practitioners of aromatherapy in the US and UK, while medical doctors dispense it in France and Germany. [1]
United Kingdom. A 1997 paper from the Aromatherapy Organisations Council described a working party set up in 1990 because doctors and other health professionals were concerned about training standards, codes of conduct and standards of practice. It also noted that the range of courses could be confusing, including massage courses in further education colleges claiming recognized aromatherapy qualifications. [3] A 2004 paper studied how practitioner associations, aromatherapy among them, were professionalizing in the UK after a 2000 Parliamentary inquiry. [4] Neither tells us the position today, and we did not read a current UK source, so we cannot say how UK rules stand now.
What the titles can and cannot tell you
| Title you may see | What the sources we read say | What it does not tell you |
|---|---|---|
| Aromatherapist | No license is required to practice in the US or UK. [1] | The length or quality of training. |
| Certified aromatherapist | Professional organizations, not governments, certify practitioners in general. [2] | Whether the certifying body is recognized by a government or by other professions. |
| Licensed (in another field) | Some aromatherapy practitioners are nurses or other licensed health professionals, and courses for licensed health professionals exist. [1] | That the license covers aromatherapy training. |
| Clinical, registered, master | Not defined in the sources we read. | Anything reliable on its own. |
What an aromatherapist can and cannot claim
NCCIH notes that state laws vary widely in the services complementary health practitioners are allowed to offer. [2] Separately, the US Food and Drug Administration (FDA) treats claims that a product will relieve pain, treat anxiety or help you sleep as drug claims. [5] For what aromatherapy research does and does not show, see Aromatherapy: practices and what research shows and Essential oil claims checked. For the massage side, see Aromatherapy massage: what the oils add.
Practitioners can have reactions too. The NCI summary notes that a few cases of contact dermatitis have been reported, mostly in aromatherapists with prolonged skin contact with essential oils. [1]
Questions to ask before booking
NCCIH's tip sheet for choosing any complementary health practitioner suggests you:
- Ask your doctor or other health care provider, a nearby hospital or medical school, professional organizations or state licensing boards for names. [6]
- Find out about the person's education, training, licensing and certifications. [6]
- Ask whether the practitioner is willing to work with your conventional providers, and explain all your health conditions, including pregnancy, asthma or allergies. [6]
- Tell all your health care providers about the approaches you use. [6]
Whatever the title, it is worth asking whether the person is trained to work with your health conditions. A pharmacist or clinician can help you weigh any oil against your medicines.
Frequently asked questions
Do aromatherapists need a license?
The NCI summary says no license is required to practice aromatherapy in the US or the UK. [1] A practitioner may hold a license in another field, such as nursing.
Does "certified aromatherapist" mean government approved?
Not by itself. NCCIH says government agencies grant licenses while professional organizations certify practitioners. [2]
Are nurses aromatherapists?
Some are. The NCI summary says nurses have tended to be the primary practitioners of aromatherapy in the US and UK. [1]
Can an aromatherapist treat a disease?
The sources we read do not say what an aromatherapist may legally treat. NCCIH says allowed services vary by state, and the FDA says product claims to treat disease are drug claims. [2] [5] See a clinician for medical problems.
How do I check a practitioner's background?
NCCIH suggests asking about education, training, licensing and certifications, and checking with licensing boards or professional organizations. [6]
