Quality Assurance

Identity Verification

What you see on the label is exactly what’s inside. Without compromise. We use four distinct tests to verify identity:

The identification and quality of each ingredient requires a "match" between the tested material and the specifications listed in our database. Our specifications guarantee a consistent product each time, and you can rest assured that what’s inside the bottle is exactly what is stated on the label.

While modern analytical technology is exciting, the human senses are still superior for assessing the freshness and quality of a product. This is known as organoleptic assessment. A trained technician scrutinizes color, flavor, texture, aroma and particle size. If the plant passes our taste and sniff test, often considered the toughest inspection of all, it gets the green light to move on to the next test.

Microscopic assessment relies on the eyes, a hand-held magnifying glass, a jeweler’s loupe, and compound and dissecting microscopes. This process gives us an up- close look at plant parts for botanical identity.

For macroscopic analysis we use our 20/20 vision. This method of plant material identification uses traits that are visible to the naked eye so we can verify we have the right plant.

We use High Performance Thin-Layer Chromatography (HPTLC), a state-of-the-art method, to confirm the identity and purity of botanical ingredients compared against a universally known “fingerprint” for the botanical ingredients. 



Research shows that whole herbs contain a multitude of supporting constituents. They work together to increase the activity of that single isolated compound. Instead of merely isolating specific compounds, we focus on the synergistic activity of the whole plant.

Using high-performance liquid chromatography (HPLC) testing we can determine the levels of bioactive components in our herbs and use that information to maximize our growing and harvesting practices, helping us achieve the highest levels of these active constituents. This test has also proven that by processing fresh herbs immediately, the naturally occurring compounds are often more potent. 

Purity Assessment

When testing plant material for purity, three tests are used to check for contaminants and to verify that all levels are well below our specification limits.

Microbiological screening tests for pathogenic  E. coli bacteria, salmonella, total aerobic bacteria, yeast and mold.

Using a digital moisture analyzer and water activity meter, we test for moisture and water activity, respectively. This ensures there isn't too much water in our dried herbs If the water activity is low, microbial growth is limited or halted completely. Excessive moisture creates an environment for microbial activity, making the plant material susceptible to mold and bacterial growth which can create unhealthy toxins.

With atomic absorption spectroscopy we test for heavy metals, including lead, cadmium and arsenic. Only raw materials with acceptable, low levels are approved.

GC-MS/MS testing detects pesticides and residual solvents. Soil analysis is important, too. We test our soil for heavy metals, organic matter, pH, and nutrient levels to ensure maximum crop growth and quality and to build regenerative soil for the future.
