Licorice and Mulethi Extract: Specification and Safety Considerations
Licorice is one of the traditional materials where the level genuinely matters, and that makes professional input a requirement rather than a courtesy. Specify the marker and the level, and obtain qualified advice on appropriate intake, duration and who should avoid it.
Why This Material Needs Advice
This guide is for brand owners and formulators sourcing licorice or mulethi in India.
Licorice, Glycyrrhiza glabra, has extensive traditional use and a well-characterised principal constituent. That constituent has recognised physiological effects, and international authorities have given attention to intake levels and duration of use because of them.
For a brand owner the implication is specific: this is not an ingredient to include at whatever level a supplier proposes or a formulation seems to need. Appropriate levels, duration of use guidance, and who should avoid the product are professional questions, and they should be settled before formulation rather than after.
Deglycyrrhizinated preparations exist, where the principal constituent has been substantially reduced. If your formulation uses one, specify it explicitly, since it is a materially different ingredient from standard extract.
Specification Elements
What belongs in your purchase specification.
| Element | What to Specify | Why |
|---|---|---|
| Botanical name | Stated | Related species exist |
| Plant part | Root | The used part |
| Identity confirmation | Per batch, method named | Standard control |
| Preparation type | Standard extract or deglycyrrhizinated | Materially different ingredients |
| Marker compound | Named with target percentage and range | Determines the active level |
| Test method | Named for the assay | Different methods, different numbers |
| Extraction ratio | Stated | Insufficient alone |
| Solvent system | Stated with residual limits | Affects profile and compliance |
| Heavy metals | Limits per batch | Root material |
| Microbial | Limits per batch | Standard |
| Pesticide residues | Per sourcing and market | Often required for export |
Specify the marker as a range rather than a minimum. A minimum alone permits batches well above your intended level, which matters more here than for most ingredients.
Formulation Points
Two practical considerations.
Licorice is intensely sweet and distinctive in taste, which affects every format it appears in. In a blend it can dominate the flavour profile at relatively low inclusion, and in a drink format that may be welcome or unwelcome depending on the product. Approve taste against a physical sample in the intended preparation.
Second, licorice appears in many traditional blends, which means it may be present in several products a consumer takes simultaneously. That is a reason for conservative inclusion levels and clear labelling rather than maximising the content.
Labelling and Guidance
Beyond the claim set.
Declare the Level
State the extract and its marker level so a consumer or professional can see what the product contains.
Duration Guidance
Where your adviser recommends a duration limit, state it clearly rather than implying indefinite use.
Who Should Avoid
Include the warnings your professional adviser recommends, prominently rather than in small print.
Professional Referral
Guidance to consult a qualified professional, particularly for anyone on medication or managing a condition, is appropriate here.
This is a category where conservative labelling is both the safer and the more credible choice, since informed buyers recognise an ingredient handled carefully.
Claim Limits
Traditional use is extensive and claims remain unavailable.
A food-framework supplement cannot claim to treat, cure or prevent any condition, which excludes digestive condition claims, respiratory condition claims and the other therapeutic uses associated with this material traditionally.
If therapeutic positioning is essential to the product, the Ayurvedic medicine route is a separate licensing decision taken before formulation, with its own composition and presentation framework.
Keep traditional-use framing factual and avoid implying clinical outcomes.
Sourcing Checklist
Complete before a first order.
- Obtain professional advice on levels, duration, warnings and exclusions.
- State the botanical name and root as the plant part.
- Specify whether standard or deglycyrrhizinated preparation.
- Require identity confirmation per batch with the method named.
- Specify the marker compound as a range, not a minimum.
- Name the assay method.
- Confirm extraction ratio and solvent system with residual limits.
- Agree heavy metal and microbial limits per batch.
- Decide pesticide screening scope.
- Approve taste against a physical sample in the intended preparation.
- Keep inclusion levels conservative given use across multiple products.
- Declare the extract and marker level on the label.
- Include duration guidance and advised warnings prominently.
- Verify licence scope for your dosage form and category.
- Write a claim set excluding digestive and respiratory condition claims.

Frequently Asked Questions
Why does licorice need professional input on levels?
Because its principal constituent has recognised physiological effects, and international authorities have given attention to intake levels and duration of use. Appropriate levels, duration guidance and exclusions are professional questions, not formulation preferences.
What is a deglycyrrhizinated preparation?
One where the principal constituent has been substantially reduced. It is a materially different ingredient from standard extract, so specify explicitly which you are buying rather than treating them as interchangeable.
Should I specify a marker minimum or a range?
A range. A minimum alone permits batches well above your intended level, which matters more for this ingredient than for most because the level itself is the safety-relevant variable.
Why keep inclusion levels conservative?
Because licorice appears in many traditional blends, so a consumer may be taking it in several products simultaneously. Conservative levels and clear labelling handle that better than maximising content in any one product.
Can I make digestive or respiratory claims?
No. A food-framework supplement cannot claim to treat, cure or prevent any condition, which excludes the therapeutic uses traditionally associated with this material. Keep traditional-use framing factual without implying clinical outcomes.
