Back to Traditional Healing SystemsWhat clinical herbalism is
Clinical herbalism is the practice of working one-to-one with people to choose plant-based preparations, usually after a consultation. In the United States, the American Herbalists Guild (a professional body) describes it as a profession and says it recognizes both traditional herbal practice and modern science-based clinical phytotherapy. [1] In the UK, a practitioner-body website says a herbalist will take a full medical history and consider any prescribed medicines or supplements you take. [2] That is how the practice is described by its own bodies. It is not a finding about how well it works.This page covers how herbalists are trained and regulated and how to check one. For the history, see the history of Western herbalism and Western herbal traditions. Plant-by-plant evidence is on herb research and evidence.
Credentials you may see
A license is granted by a government agency. Professional organizations certify or register their members, and NCCIH notes that being licensed or certified is not always a guarantee of being qualified. [3]- United States, American Herbalists Guild: the Registered Herbalist, RH(AHG), is a membership designation. The Guild says it requires meeting its Core Competencies and says it is one of many ways herbalists show their skills. [6] It is a peer-review credential from a professional body, not a state license.
- United Kingdom, Unified Register of Herbal Practitioners: a professional association and register of qualified herbal practitioners. [7] The European Herbal and Traditional Medicine Practitioners Association issues the HerbMark to members of its affiliated associations and describes the market as largely unregulated. [8]
- United Kingdom, Professional Standards Authority: it accredits registers of practitioners not regulated by law. [9] The NHS advises choosing a private therapist registered with a professional organisation accredited by the Authority. [4]
We do not list or recommend practitioners. See how to check a traditional practitioner and questions to ask a herbalist.
What research shows
Proper evidence not found for the practice of individualized clinical herbalism as a whole. We searched PubMed for systematic reviews of individualized herbal consultation and found none we could use. Evidence exists for particular herbs and conditions, with results ranging from promising to none. Judge each herb separately. The NHS notes herbal medicines are not tested in the same way as standard medicines. [4]Who should seek conventional care first
See a doctor for symptoms that do not go away or keep coming back, rather than only talking to a therapist. [4] Never stop a prescribed medicine without talking to your doctor. [4]Frequently asked questions
Is a herbalist the same as a doctor?
No. A herbalist is a practitioner trained in plant-based approaches. Whether any title is protected by law depends on the country and state. [3]
Do herbalists need a license?
It varies. In the UK, herbal practitioners do not need to be registered by law. [4] In the US, credentials are decided state by state. [3]
What does RH(AHG) mean?
It is a Registered Herbalist membership designation from the American Herbalists Guild, based on its Core Competencies. [6]
Can I see a herbalist while taking prescribed medicines?
Tell both the herbalist and your doctor or pharmacist. Some herbs change how medicines work. [10][4]
How do I find a herbalist near me?
We do not list practitioners. Check their training, whether they belong to an accountable professional body, and what the law says where you live. [3][9]

Training and regulation depend on where you live
Qualifications differ by country, and in many places herbalism is not regulated by law. Check the rules where you live.
| Place | What the sources we read say |
|---|---|
| United States | NCCIH says there is no standardized national system for credentialing complementary health practitioners, and states decide what credentials are needed. [3] Its examples are professions such as chiropractic, naturopathic medicine and massage. We did not find a source stating a rule for herbalists, so ask your state licensing agency. |
| United Kingdom | A practitioner-body site says there is currently no mandatory regulation of herbalists in the UK, and about 2,500 practice. [2] The NHS says herbal medicine practitioners do not need to be registered by law. [4] |
| Australia | An older journal study found no real self-regulation of naturopathy and Western herbal medicine and recommended statutory regulation. [5] Check the current position with the national health regulator. |
| Canada and elsewhere | Proper evidence not found: we could not read a regulator page, so we make no statement. |
Safety, quality and interactions
Natural does not always mean safe. [10]
- Medicines: St. John's wort, for example, makes many medications less effective. [10] The NHS says to check with a pharmacist before taking a herbal medicine if you take other medicine. [4] See how interactions work.
- Liver: more cases of sudden liver damage are being reported in people taking dietary supplements. [10]
- Quality: what is on the label may not be what is in the product. [10] In the US, the FDA can act against adulterated or misbranded supplements only after they are on the market. [10]
- Pregnancy, children: many supplements have not been tested in pregnant women, nursing mothers or children. [10] The NHS says herbal medicines are not recommended for children. [4]
- Online: the NHS advises not to buy unlicensed herbal medicines online. [4]
Tell every clinician you see about the herbs you use. [4] For poisoning in the US, Poison Help is 1-800-222-1222 (see poison help by country).
