Apply for a traditional herbal registration (THR)

How to apply for a traditional herbal registration (THR) to market a herbal medicine in the UK.

You must apply for a traditional herbal registration (THR) before you can market a traditional herbal medicinal product in the UK.

A THR is only granted if the medicine is used for minor health conditions where medical supervision is not required (e.g. a cold).

If your traditional herbal medicinal product claims to treat major health conditions, you need to apply for a marketing authorisation before you can place it on the market.

How to apply

Complete the application form for a traditional herbal medicine (PDF, 1.12 MB, 24 pages) and submit it with the required documents below.

Required documents

You must include scientific evidence with your application relating to the safety, quality and traditional use of the herbal product. This includes:

  • a technical dossier covering the quality of herbal ingredients in the electronic Common Technical Document (eCTD) format for traditional herbal medicinal products
  • review of safety with an expert report including clinical and non-clinical safety areas carried out by either:
    • a registered doctor
    • a registered pharmacist
    • a scientifically qualified competent individual (eg toxicologist)
    • herbal practitioner who is a member of a professional body
  • draft summary of product characteristics
  • a mock-up label and patient information leaflet (PIL): see best practice guidelines on this

You can request advice before you submit your application for advice on whether your product is likely to meet the THR scheme requirements by completing the template for notification of application for THR (MS Word Document, 321 KB) and emailing it to

THR Certification Mark

The THR Certification Mark should be included on the mock up label and patient information leaflet to show that the product meets the required standards of quality, safety and evidence of traditional use. See guidelines (PDF, 22.2 KB, 4 pages) on the usage of the mark.

Submit your application

Submit your application form with the required documents via MHRA Submissions.

You need to submit your application using the eCTD format. If you can’t use eCTD you can use the Non-eCTD electronic Submissions (NeeS) process.

Email if you have any questions about submitting your application.

The MHRA usually takes 210 days to evaluate your application if we receive all the required documents and they are valid .

Herbal medicinal product: definition

According to the Human Medicines Regulations (2012), a product is an herbal medicinal product if the active ingredients are herbal substances and/or herbal preparations only.

An herbal substance is a plant or part of a plant, algae, fungi or lichen, or an unprocessed exudate of a plant, defined by the plant part used and the botanical name of the plant, either fresh or dried, but otherwise unprocessed.

An herbal preparation is when herbal substances are put through specific processes, which include:

  • extraction
  • distillation
  • expression
  • fractionation
  • purification
  • concentration
  • fermentation

The herbal substance being processed can be:

  • reduced or powdered
  • a tincture
  • an extract
  • an essential oil
  • an expressed juice
  • a processed exudate (rich protein oozed out of its source).

Not all herbal products are medicines, some can be classified as food supplements or cosmetics.

Check the guide on what is considered a medicinal product before applying for a THR.

See the list of herbal medicines granted a THR.

Eligibility for the THR Scheme

You must ensure the indication of the herbal medicinal product is suitable for the Traditional Herbal Registration Scheme.

The indication is the medical condition the product has traditionally been used to treat. Check the permitted indications (PDF, 154 KB, 6 pages) to see if your herbal medicinal product is eligible under the Traditional Herbal Registration Scheme.

You must also show evidence that the herbal medicinal product has been traditionally used to treat the stated condition for a minimum of 30 years.

  • For products intended to be marketed in the whole of the UK or Northern Ireland only, at least 15 years of the 30 years of use must relate to use in the EU/EEA.
  • For products intended to be marketed in Great Britain (England, Wales and Scotland) only, the MHRA may be able to accept the 15 years of traditional evidence from a wider range of countries in addition to the UK and EU/EEA countries.

Suitable countries will be those that have a level of pharmacovigilance equivalent to that of the UK. This is to ensure that any safety issues have been properly identified to support the traditional use of the product. The MHRA will publish a list of suitable countries for this purpose on the website and update this list as new entries arise.

See guidance on sources of evidence to show traditional use and safety (PDF, 126 KB, 4 pages) of the product.

Applicants are strongly encouraged to contact the MHRA at an early stage, using our template for notification of application for THR (MS Word Document, 321 KB) should they have any questions.

Banned or restricted herbal ingredients

Some herbal ingredients are toxic and cannot be used in the manufacture, import and sale of unlicensed medicines in the UK. There are also restrictions on how some herbal ingredients can be used in medicines. Check the list of banned and restricted herbal ingredients before you submit your application to ensure your ingredients are acceptable for the Traditional Herbal Registration Scheme.

Exemptions for THR

If you’re an herbal practitioner, you don’t need a licence to supply herbal medicinal products you create on your premises to patients following one-to-one consultations.
