What we do

The National Institute of Medical Herbalists (NIMH) is the United Kingdom’s leading professional body and voluntary regulator of herbal practitioners. 

The Institute promotes the benefits, the efficacy and the safe use of herbal medicine.  Our members treat hundreds of thousands of patients every year. By choosing a NIMH member as your herbal medicine practitioner you can be confident of their high standards of training and professional conduct.

The Institute carries out a range of activities that help ensure NIMH members offer the highest standards of herbal medicine practice.

The NIMH undertakes key functions:

  • Maintains a Register of individual members.
  • Sets the profession’s educational standards.
  • Runs an accreditation system for training establishments.
  • Maintains mandatory programmes of professional development.
  • Provides codes of conduct, ethics and practice.
  • Operates complaints and disciplinary procedures.
  • Represents the profession, patients and the public through participation in external processes such as regulation of the profession and herbal medicine.
  • Ensures that all NIMH Members have professional indemnity, public liability and medical malpractice insurance.
  • Operates a mandatory comprehensive block insurance scheme.

The organisation has a long and illustrious history. It was first established as the National Association of Medical Herbalists in 1864 by a group of herbalists from the north of England. Today the National Institute of Medical Herbalists has members throughout the United Kingdom and internationally.


NIMH Accreditation

The National Institute of Medical Herbalists (NIMH) sets high standards for entry to the profession. In 1996 the NIMH established an Accreditation Board to assure and maintain those high standards through independent assessment of courses leading to NIMH membership. The NIMH Accreditation Board has accredited courses since that time.

In 2004, the members of the NIMH agreed to recognise the Western Herbal Medicine courses then being accredited by the European Herbal and Traditional Medicine Practitioners Association (EHTPA), provided those courses meet the standards for entry to the NIMH. Students graduating from a BSc Herbal Medicine course and PGDip/MSc accredited by NIMH or EHTPA are eligible to apply for membership of NIMH.

NIMH is currently piloting a method to consider applicants who have not graduated from an accredited course. If you would like to be considered for membership, you are invited to write to NIMH Admissions Board outlining your background and qualifications. Please register your interest in this process with the NIMH admission officer at admissions@nimh.org.uk.

The following BSc Herbal Medicine and PGDip/MSc courses  are accredited by the NIMH or the EHTPA. Graduates of these courses are eligible to apply for NIMH membership.

The NIMH reserves the right to seek additional information from graduates (for example in relation to previous criminal convictions). Graduates from NIMH accredited courses will be eligible to apply to the NIMH for admission to membership.
