Clean Label Assurance: Why Grether’s Pastilles Are Tested for the Purity You Can’t See

In today's market, consumers are no longer satisfied with simply reading a product's ingredient list. They want to know what's not in the product, specifically concerning hidden environmental contaminants, pesticides, and industrial chemicals. This demand for radical transparency is what the Clean Label Project was created to address.

Grether’s Pastilles are proud to be Clean Label Project Certified. This certification adds a modern, science-backed layer of trust to a 150-year-old tradition of quality, assuring you that the product you put in your mouth is as pure as it is effective.

What is the Clean Label Project, and Why Does it Matter?

Snippet Answer: The Clean Label Project is a non-profit organization that uses independent, third-party testing to certify products for purity, screening for hundreds of environmental and industrial contaminants that are often not required to be listed on a standard label.

Federal food standards primarily focus on known pathogens (like bacteria). However, they don't always fully account for the accumulation of environmental toxins like heavy metals (arsenic, lead, mercury), pesticide residues (including glyphosate), or plasticizers that can migrate from packaging.

The Clean Label Project goes beyond these minimum legal requirements by proactively testing finished products purchased directly from retail—mirroring the consumer experience—to provide an extra level of assurance about product purity.

The Hidden Threats That Don't Appear on a Label

The certification process is rigorous and focuses on substances of concern:

• Heavy Metals: Testing for toxic elements like lead, cadmium, and arsenic that can enter ingredients through soil or water.

• Pesticides & Herbicides: Screening for hundreds of common residues, including glyphosate (Roundup).

• Plasticizers: Checking for chemicals like BPA and Phthalates that can leach from packaging materials.

By achieving this certification, Grether's Pastilles demonstrates that the product you are dissolving is held to a far higher standard of purity than basic compliance requires.

How Grether’s Pastilles Earned the Certification

Snippet Answer: Grether's earned the certification by submitting to the Clean Label Project's independent testing process, where unannounced retail samples were analyzed by an ISO-accredited lab and found to be compliant with strict standards for low levels of environmental contaminants.

The certification process is designed to be unbiased and thorough, verifying a brand's commitment to quality at every step:

1. Consumer Chain of Custody Sampling: The Clean Label Project purchases Grether's Pastilles samples directly from retail stores or online—just like any consumer—to ensure the finished product being tested is exactly what customers receive.

2. ISO-Accredited Lab Testing: Samples are sent to independent, third-party laboratories for comprehensive analytical chemistry testing.

3. Contaminant Screening: The pastilles are screened for hundreds of potential contaminants, and the results are benchmarked against strict standards, often inspired by California's stringent Proposition 65 and European Union regulations.

4. Ongoing Compliance: Certification is not a one-time event. Grether’s must maintain these high standards, as the Clean Label Project performs unannounced, ongoing sampling and testing to ensure continued compliance.

The Link Between Swiss Craftsmanship and Purity

Grether's has always championed natural, high-quality ingredients, from the real blackcurrant juice concentrate to the vegetable-sourced glycerin. The Clean Label Project Certification validates that this commitment to raw ingredient quality and the meticulous Swiss manufacturing process translates into a final product that is not just effective, but also exceptionally clean.

What This Means for Your Voice and Your Health

For the consumer, the Clean Label Project seal is a powerful reassurance that Grether's Pastilles is a product that supports long-term wellness without compromise.

• Confidence for Vulnerable Users: If you are a professional who consumes pastilles frequently, or if you are looking for remedies for children, knowing the product is screened for heavy metals and pesticides offers invaluable peace of mind.

• Focus on Efficacy: You can trust that the soothing effect you feel is purely the result of the glycerin coating your throat and not a temporary masking effect from synthetic chemicals or questionable additives.

• True Transparency: The certification is the ultimate expression of transparency—a proactive decision by the brand to subject its product to an independent, non-mandatory safety audit.

When you reach for a tin of Grether's Pastilles, you are choosing a product that has been celebrated for its efficacy since 1850 and is now certified for its purity by modern, cutting-edge science.
