MHRA Herbal Registration: Traditional Herbal Medicinal Products

Navigating MHRA Herbal Registration for Traditional Herbal Medicinal Products in the UK

MHRA herbal registration is the mandatory process by which the Medicines and Healthcare products Regulatory Agency (MHRA) authorises Traditional Herbal Medicinal Products (THMPs) for sale in the UK, ensuring they meet stringent safety, quality, and traditional use standards. This registration is crucial for businesses to legally market herbal remedies that make specific therapeutic claims, distinguishing them from food supplements. Without it, products making medicinal claims, even based on historical use, are considered unlicensed medicines, risking significant regulatory penalties.

In this guide, you will learn:

• How to accurately classify your herbal product as a food supplement or a medicinal product.
• The specific requirements and benefits of the Traditional Herbal Registration (THR) scheme.
• A step-by-step breakdown of the MHRA application process and ongoing compliance.
• Key differences between food supplement herbs and traditional herbal medicinal products.

What Defines a Herbal Medicinal Product in the UK?

A herbal medicinal product in the UK is defined primarily by its intended purpose: it is presented as having properties for treating or preventing disease, or it is intended to restore, correct, or modify physiological functions through pharmacological, immunological, or metabolic action. This critical distinction, outlined in Regulation 2 of the Human Medicines Regulations 2012, dictates whether your product falls under medicine law or food law. Businesses often mistakenly classify products, leading to significant compliance issues.

The Medicines and Healthcare products Regulatory Agency (MHRA) is the authority responsible for regulating medicines, including herbal medicinal products. Our experience at Label Checker shows that misclassification is one of the most common and costly errors businesses make. For example, a product claiming to "alleviate cold symptoms" or "reduce anxiety" is likely to be considered medicinal, regardless of its natural ingredients.

"A product is a medicinal product if it is presented as having properties for treating or preventing disease in human beings; or it may be used in, or administered to, human beings with a view to restoring, correcting or modifying physiological functions by exerting a pharmacological, immunological or metabolic action, or to making a medical diagnosis." — Regulation 2, Human Medicines Regulations 2012 (SI 2012/1916)

The MHRA's "Borderline Products" guide is an invaluable resource for classification. It helps determine if a product falls under medicines legislation or other frameworks like food law, cosmetics, or medical devices. Understanding this guide is the essential first step for any business dealing with herbal products. You can access the MHRA's detailed guide on Borderline Products here._

The MHRA considers several factors to classify a product:

• Presentation: How the product is labelled, advertised, and promoted. Does it make therapeutic claims?
• Ingredients: Are the ingredients known to have pharmacological effects? What is their concentration?
• Function: What is the intended effect of the product on the human body?
• Dosage: Is the recommended dosage consistent with a medicinal use?
• Route of Administration: Is it ingested, applied topically, or administered otherwise?

For instance, a high-concentration St. John's Wort product marketed for "mood support" with explicit antidepressant claims would almost certainly be medicinal. Conversely, a low-dose herbal blend with general wellbeing claims might be a food supplement. This distinction is crucial because food supplements are regulated by the Food Standards Agency (FSA) under food law, while medicinal products require MHRA authorisation. For more details on food supplements, consult the FSA's guidance here._

What is the Traditional Herbal Registration (THR) Scheme?

The Traditional Herbal Registration (THR) scheme is a simplified regulatory pathway in the UK for certain traditional herbal medicinal products, designed to ensure their safety, quality, and plausible efficacy based on a long history of use. Introduced to bring traditional remedies, previously existing in a legal grey area, under a formal regulatory framework, the THR scheme acknowledges centuries of herbal medicine practice. It ensures products meet modern standards without requiring extensive clinical trials for efficacy.

The scheme is specifically for products with a documented history of traditional use, typically at least 30 years, including at least 15 years within the UK/EU/EEA. This historical evidence serves as proof of the product's plausible efficacy and safety under specified conditions. Products granted a THR are issued a unique THR number, which must be displayed on packaging, providing consumers with reassurance.

Key Features and Benefits of the THR Scheme

The THR scheme offers a pragmatic route to market for traditional herbal remedies. It balances the need for robust regulation with the recognition of established historical use.

• Simplified Application: Unlike conventional medicines requiring extensive clinical trial data, THR applications rely on documented evidence of traditional use.
• Safety and Quality Assurance: Products must meet stringent safety and quality standards, including Good Manufacturing Practice (GMP), ensuring consistency and purity.
• Specific, Traditional Claims: Claims are restricted to those based on traditional use, such as "traditionally used for the relief of mild anxiety" or "for the symptomatic relief of colds." No claims implying immediate or specific therapeutic effects are permitted.
• No Clinical Efficacy Data: Proof of efficacy through clinical trials is not required, only plausibility based on historical use.
• MHRA Authorisation: Products receive a unique THR number, signifying MHRA approval and compliance.

Without a THR, any product making medicinal claims, even based on traditional use, would be considered an unlicensed medicine, subject to enforcement action by the MHRA. This can lead to product recalls, fines, and reputational damage, as many businesses have unfortunately discovered.

How Do I Apply for MHRA Herbal Registration?

Applying for MHRA herbal registration under the THR scheme is a meticulous process that demands thorough preparation and a deep understanding of regulatory requirements. The MHRA provides comprehensive guidance, which is the essential starting point for any applicant. Our 30 years of experience show that attention to detail at each stage is paramount to success.

Step-by-Step Guide to a THR Application

1. Pre-Application Assessment (Borderline Classification): Before anything else, confirm your product is indeed a herbal medicinal product suitable for the THR scheme. If there’s any ambiguity, consult the MHRA's Borderline Products Guide or seek expert advice. Attempting to register a food supplement as a medicine, or vice-versa, will lead to delays and rejection.

2. Gathering Documentation for Traditional Use: The cornerstone of a THR application is robust evidence of traditional use. This typically involves:

   • Bibliographic evidence: References from pharmacopoeias, scientific literature, and traditional medicine texts demonstrating the product's use for at least 30 years, with at least 15 years within the UK/EU/EEA.
   • Expert opinions: Statements from qualified experts in herbal medicine.
   • Marketing history: Evidence of previous marketing in the UK/EU/EEA, if applicable. This evidence must comprehensively demonstrate the proposed traditional indication, dosage, and route of administration.

3. Quality Dossier Preparation: Even without clinical trials, a robust quality dossier is essential. This includes:

   • Detailed specifications: For the herbal substance, herbal preparation, and the finished product.
   • Manufacturing process: Description of the manufacturing method, adherence to Good Manufacturing Practice (GMP), and quality control measures.
   • Stability data: Evidence that the product remains stable and potent throughout its shelf life.
   • Impurity profiles: Data on potential contaminants, pesticides, heavy metals, and microbial limits.
   • Excipient information: Details of all non-active ingredients. This section ensures the product's consistency, purity, and overall quality.

4. Safety Data Submission: While full clinical safety trials are not required, applicants must provide a safety report demonstrating the product is safe for its intended traditional use. This involves:

   • Pharmacovigilance data: Information on adverse reactions reported historically.
   • Toxicology data: If available, non-clinical toxicology studies or references to established safety profiles.
   • Contraindications and warnings: A comprehensive list of situations where the product should not be used, potential interactions, and special precautions. The MHRA assesses whether the product's benefits, based on its traditional use, outweigh any identified risks.

5. Labelling and Patient Information Leaflet (PIL) Design: All packaging and accompanying leaflets must comply with specific MHRA requirements for herbal medicinal products. This includes:

   • The THR number prominently displayed.
   • The specific traditional indication.
   • Dosage instructions.
   • Warnings, contraindications, and potential side effects.
   • Storage conditions.
   • Manufacturer details.
   • The statement "Traditional herbal medicinal product for use in [specified indication] exclusively based upon long-standing use." Accuracy and clarity are paramount to ensure consumer safety and informed choice. For general UK labelling, see our guide on UK Food Supplement Labelling Requirements: Complete 2026 Guide.

6. Submission and Evaluation: The complete dossier is submitted to the MHRA. The agency then undertakes a rigorous evaluation process, which can take several months. They may request further information or clarification during this period.

7. Post-Authorisation Responsibilities: Once a THR is granted, manufacturers must adhere to ongoing pharmacovigilance requirements, report any adverse reactions, and ensure all marketing and labelling remain compliant. Any changes to the product or manufacturing process may require a variation application to the MHRA.

The complexity of this process often necessitates expert guidance. Our team at label-checker.com specialises in helping businesses navigate these intricate regulatory pathways, ensuring your applications are robust and compliant.

How Do Food Supplement Herbs Differ from Traditional Herbal Medicinal Products (THMPs)?

The distinction between food supplement herbs and Traditional Herbal Medicinal Products (THMPs) is a frequent source of confusion and a common area of non-compliance, often leading businesses to inadvertently market unlicensed medicines as food supplements. This distinction is not merely semantic; it dictates the entire regulatory pathway, from manufacturing standards to labelling and marketing claims. Our compliance experts regularly encounter businesses struggling with this classification, highlighting the need for clear guidance.

Many businesses face enforcement action from the MHRA because their "food supplement" is making implied medicinal claims. For example, using images of sick people, medical crosses, or language that strongly suggests a therapeutic effect can lead to reclassification as an unlicensed medicine, even without explicit claims. The MHRA's interpretation of "medicinal product by presentation" is broad and considers the overall impression.

Here’s a clear comparison:

What Role Does GMP Play in the THR Scheme?

Good Manufacturing Practice (GMP) is a foundational and non-negotiable requirement within the Traditional Herbal Registration (THR) scheme. For any product to be granted an MHRA herbal registration, its manufacturing process must adhere to the stringent GMP standards applicable to medicines. This is a significant differentiator from food supplements, which typically follow general food hygiene regulations.

GMP ensures that products are consistently produced and controlled according to quality standards appropriate for their intended use and as required by the product specification. For herbal medicinal products, this covers every aspect of production, from the starting materials, premises, and equipment to the training and personal hygiene of staff. Non-compliance with GMP is a critical failure point for many businesses seeking THR.

Key Aspects of GMP for Herbal Medicinal Products:

* **Quality Management System:** A comprehensive system ensuring products are consistently manufactured and controlled to the required quality standards. * **Personnel:** Sufficient qualified and trained personnel for all operations, with clearly defined roles and responsibilities. * **Premises and Equipment:** Suitable premises and equipment, regularly maintained and calibrated to prevent contamination and errors. * **Documentation:** Detailed written procedures and records for every stage of manufacturing, quality control, and distribution. This includes batch records, specifications, and validation reports. * **Production:** Clear, documented processes for all manufacturing steps, from receipt of raw materials to release of finished products, ensuring consistency. * **Quality Control:** Robust testing of raw materials, in-process samples, and finished products to ensure they meet specifications before release. * **Complaints and Recalls:** Established systems for handling complaints and efficiently recalling defective products from the market.

Adherence to GMP is not just a regulatory hurdle; it is fundamental to ensuring the safety, quality, and consistency of herbal medicinal products. The MHRA conducts inspections to verify GMP compliance. Non-compliance can lead to refusal of a THR application, suspension of an existing THR, or even prosecution. For businesses transitioning from food supplement manufacturing to herbal medicinal products, investing in GMP compliance is a substantial undertaking, often requiring significant changes to facilities, processes, and quality control systems, but it is absolutely essential for successful MHRA herbal registration.

What Are the Post-Registration Compliance Requirements?

Obtaining an MHRA herbal registration is not the finish line; it marks the beginning of continuous, rigorous compliance responsibilities. Holders of a THR must actively monitor the safety and quality of their products and adhere to pharmacovigilance requirements to maintain their authorisation. Neglecting these ongoing duties can lead to serious consequences, including fines, product recalls, and even the revocation of the THR.

Our team at Label Checker has observed many businesses falter post-registration due to a lack of understanding or resources for ongoing compliance.

Ongoing Compliance Obligations:

1. Pharmacovigilance: THR holders are required to operate a pharmacovigilance system to collect, assess, and report any adverse reactions associated with their products. This includes:

   • Maintaining a detailed record of all suspected adverse reactions.
   • Reporting serious adverse reactions to the MHRA within specific timeframes.
   • Periodically submitting safety reports (Periodic Safety Update Reports - PSURs) to the MHRA. This continuous monitoring ensures any new safety concerns are identified and addressed promptly, safeguarding public health.

2. Quality Control and Batch Release: Each batch of a THR product must undergo rigorous quality control testing and be certified by a Qualified Person (QP) before release onto the market. This ensures every product reaching consumers meets the registered specifications.

3. Variations to the THR: Any changes to the product – including formulation, manufacturing process, specifications, or labelling – must be submitted to the MHRA as a variation application and approved before implementation. This maintains the integrity of the registered product.

4. Advertising and Marketing Compliance: All advertising and promotional materials for THR products must comply with the Human Medicines Regulations 2012 and relevant advertising codes (e.g., CAP Code). Claims must be consistent with the approved traditional indication and must not mislead consumers or suggest efficacy beyond what is permitted by the THR.

5. Renewal of THR: Traditional Herbal Registrations are typically valid for five years and must be renewed. The renewal process requires a review of the product's safety profile and continued compliance with all regulatory requirements.

Maintaining robust quality management systems and staying informed about regulatory updates are crucial for long-term compliance. Our team at label-checker.com can assist with ongoing compliance reviews and provide expert advice on pharmacovigilance obligations.

What Are the Common Pitfalls in MHRA Herbal Registration?

Navigating the complexities of MHRA herbal registration can be challenging, and our decades of experience reveal several common pitfalls that businesses frequently encounter. Awareness of these can significantly streamline your compliance journey and prevent costly delays or rejections.

1. Misclassification of Product Type:

   • Pitfall: Incorrectly classifying a product as a food supplement when it is, in fact, an unlicensed medicinal product due to its claims or ingredients. This is arguably the most common and dangerous mistake.
   • Avoidance: Conduct a thorough borderline product assessment using the MHRA guidance. Err on the side of caution and seek expert advice if unsure. Remember, the MHRA looks at the overall impression, not just explicit claims.

2. Insufficient Evidence of Traditional Use:

   • Pitfall: Submitting an application with weak or incomplete evidence of 30 years of traditional use (15 years in the UK/EU/EEA).
   • Avoidance: Start gathering comprehensive bibliographic evidence early. Ensure the evidence directly supports the proposed traditional indication, dosage, and route of administration. Focus on reputable sources like pharmacopoeias and recognised scientific literature.

3. Non-Compliance with GMP:

   • Pitfall: Manufacturing facilities not meeting the stringent GMP standards required for medicines, leading to application rejection or product recalls.
   • Avoidance: Invest in GMP compliance from the outset. This may involve significant upgrades to facilities, equipment, and quality systems. Engage with GMP consultants or the MHRA to ensure readiness.

4. Inadequate Quality Dossier:

   • Pitfall: Providing insufficient detail on ingredient specifications, manufacturing processes, or stability data.
   • Avoidance: Prepare a robust quality dossier that meets the requirements of the Common Technical Document (CTD) format. Ensure all analytical methods are validated and specifications are scientifically justified.

5. Non-Compliant Labelling and Claims:

   • Pitfall: Using claims that go beyond the approved traditional indication or failing to include all mandatory information on packaging and PILs. (See Health Claims for Food Supplements for comparison).
   • Avoidance: Design labelling and marketing materials strictly according to the approved THR summary of product characteristics (SmPC). Train marketing teams on the specific limitations of THR claims. For specific ingredient declarations, refer to our guide on QUID Labeling.

6. Neglecting Post-Authorisation Responsibilities:

   • Pitfall: Failing to implement a pharmacovigilance system, report adverse reactions, or manage variations correctly.
   • Avoidance: Establish robust post-market surveillance systems. Designate a qualified person responsible for pharmacovigilance (QPPV) and ensure all staff are aware of reporting requirements. Plan for regular compliance audits. This also ties into broader compliance like Natasha's Law for allergen management, which can impact product safety.

By proactively addressing these potential issues, businesses can significantly increase their chances of successful MHRA herbal registration and maintain compliance throughout the product lifecycle.

Frequently Asked Questions

What is the difference between a Traditional Herbal Registration (THR) and a full Marketing Authorisation (MA)?

A THR is a simplified registration for herbal medicinal products based on a long history of traditional use, requiring evidence of safety and plausible efficacy, but not clinical trials for efficacy. A full Marketing Authorisation (MA) requires extensive clinical trial data to prove both the safety and efficacy of a product, typically for novel medicines or those making strong, specific therapeutic claims.

Can I sell a herbal product with medicinal claims in the UK without an MHRA registration?

No. Selling a product with medicinal claims without appropriate MHRA authorisation (either a THR or a full Marketing Authorisation) is illegal in the UK. Such products are considered unlicensed medicines and are subject to enforcement action, including fines, product seizure, and prosecution.

How long does the MHRA herbal registration process typically take?

The MHRA herbal registration process can take several months, often between 6 to 12 months, or even longer if the initial application is incomplete or requires significant clarification. The timeline largely depends on the quality and completeness of the submitted dossier and the MHRA's workload.

Do I need a separate THR for the UK and the EU after Brexit?

Yes. Following the UK's departure from the EU, a UK THR is required for market access in Great Britain (England, Scotland, Wales), and a separate EU THR is needed for market access in the EU. Existing EU THRs were converted to UK THRs, but new applications must be made independently to the respective authorities.

What happens if my product is misclassified by the MHRA?

If the MHRA determines your product is an unlicensed medicinal product rather than a food supplement, you will be required to cease marketing and sales immediately. You may face enforcement action, including product recalls, fines, and potentially prosecution. This underscores the importance of accurate initial classification.

Are there any specific regulations for "novel" herbal ingredients?

Yes, if a herbal ingredient does not have a history of consumption in the UK/EU before May 1997, it may fall under Novel Food Regulations. This requires pre-market authorisation based on safety assessments, regardless of its classification as a food supplement or medicinal product. For more information, see our guide on Novel Food Regulations: What Supplement Manufacturers Need to Know.
