All of our herbs are manufactured from premium quality raw materials that must pass a series of stringent inspections performed by in-house professional technicians utilizing our comprehensive process and precision instruments.
Only upon passing the above inspections for quality, identity and safety, may the herb material be accepted into our facility for processing.
- Physical Inspection
- Microscopic Inspection
- Thin Layer Chromatography (quantitative)
- High Performance Liquid Chromatography (quantitative)
Heavy Metal/Pesticide Inspection:
- UPLC-ICP-MS – Heavy Metal
- UPLC-MS/MS – Pesticides
- GS-MS/MS – Pesticides
The herbs are analyzed for its moisture content, purity, extraction and other properties.
Preparation and Verification
Once accepted, the herbs go through meticulous cleaning to remove dirt and foreign materials. Every herb, and part of herb, is unique and should be prepared according to its unique method. With certain herbs, it should be added into a formula decoction at specified stages, rather than all at once. Our formulas are extracted homogeneously, which creates synergy amongst the herbs that cannot be replicated otherwise.
This is a technique that can only be mastered over time- we take great pride in our expertise and adherence to these methods.
The herbs are placed in a rotary extractor that spins to mix the herbs in a decoction liquid, with our technicians carefully monitoring the slow increase in temperature. This precise extraction temperature and timing is strictly controlled to maximize efficiency and thoroughness.
Collection and Restoration of Essential Oil
During extraction, a vat captures and preserves the volatile oils, which are reintroduced into the herbs in the granulation phase. Essential oils increase efficacy and infuse the herbs with their natural aromatic properties, giving our granules the edge over our competitors.
The extract, in liquid form, flows through a pipeline directly into a concentration system and gradually condenses through low temperature evaporation. Maintaining low temperature preserves the potency of the extract that would otherwise be damaged under extended exposure to high temperatures.
The optimal potency extraction for each herb and formula is different, so the duration of concentration is dependent on the predetermined herb-to-solute ratio.
The concentrate, now in the form of a viscous paste, is piped into a flow coater and sprayed onto minute particles of a base material as the moisture slowly dissipates. The flow coater’s process is automated, and it is completely sealed off to prevent the possibility of cross-contamination. The base material is formed using non-GMO starch and/or ground herbs, depending on the formulation. With the moisture evaporated, the result is a fine, free flowing extract granule that is now ready to be packaged, or further processed into tablets or capsules.
Appearance and Packaging
Like all plant products, the characteristics of herbs vary from season to season. Naturally, it is normal for the resulting granules to vary slightly in color, texture and aroma. Our granule extracts are produced in batches with each batch assigned a unique lot number, which can be found on our labels. Once it passes the appearance inspection, the product is ready to be bottled.
We pick multiple samples from each production lot to measure the quality, safety and efficacy of the product, using state-of-the-art precision instruments and methods:
- HPLC- Marker ingredient analysis and verification
- UPLC-ICP-MS – Heavy Metal Analysis
- UPLC-MS/MS and GS-MS/MS – Pesticides Screening (up to 507 pesticide detection capabiliy)
- Microbial screening (E. Coli, Salmonella, Yeast and Mold, etc.)
Upon passing our finished product testing, a Certificate of Analysis (COA) will be issued. No products will leave our facility without a COA that proves that the batch has gone through meticulous testing and inspection.
