Testing in Every Step

 

Quality is always our first priority, and we insist on the highest quality at all cost. We have at times rejected products and ingredients that are not up to our standards, even though it can means increased production cost or time.

For example, in 2009, we rejected about 2 tons of herb powders, because the supplier didn't follow our specified procedures and had ground the raw herbs to powders before our screening inspection. We insist on this procedures because only in their original raw forms one can tell the difference between top-grade herbs and lower-grade herbs. 

 

Single Herb Screening

Every single raw herb to be used in our formula is identified and screened through multiple tests before processing. TLC (Thin Layer Chromatography) and HPLC (High Performance) are used to confirm identity, ensure potency and test for active constituents when necessary. The manufacturer is not allowed to proceed until we release our approval.

Processing Check

We specify the detailed method for processing each herb to maximize their effectiveness for each formula, as well as the mixing ratio and the grinding parameters. Our QA team in China monitors every step of the production process to assure that the manufacturer compliance is to our specifications.

Post-Processing Check

Finished products are sanitized to strict standards. Every batch of finished product is tested on moisture content, dissolution, heavy metals, pesticide residue and microbial content. The manufacturer is not allowed to package the products until we’ve checked the test results and sent our approval.

Third-party Testing

Regularly, samples of finished products are sent to independent labs to verify the manufacturer’s testing data. Sophisticated analyses, such as the Aristolochic Acid Test and the Chloramphenicol Testing, are conducted when needed.

Phytosanitary Check

Every batch of finished products are inspected by the CCIB (China Commodity Inspection Bureau) for the phytosanitary certificate, which certifies that the plants or plant products have been inspected according to appropriate procedures and are considered to be free from quarantine pests and practically free from other injurious pests, and that they are considered to conform with the current phytosanitary regulations of the importing country (USA).

Border Inspection

The US government has stringent standards on importing herbal products. Two organizations under the USDA, the USFW (US Fish & Widelife) and NMFS (National Marine Fisheries Service) are in charge of enforcing that all products derived from and containing derivatives of species listed in the ESA (1973 US Endangered Species acts) are prohibited from importation and interstate trade. The imported herbal ingredients are inspected by various of USA government agencies at the border, which strictly bans and/or restricts any herbs that are considered poisonous, unfit for human consumption, containing aristolochic acid or ephedrine alkaloids, and anything on the CITES (Convention on International Trade in Endangered Species of Wild Fauna and Flora).

Receiving Inspection and Testing

At receiving, our experienced QA team in the USA carefully inspect all products, ingredients, their testing data and all the required paperwork, looking for any deviations from our specifications, to make sure that our high standards are never compromised. Additional lab testing is performed on random received ingredients to verify the results matching the manufacturers' testing data.

Product Releasing Testing

At releasing a batch of product for sales, our QA team in the USA carefully inspects the product and their testing data with all the related paperwork to ensure everything meets all of our high standards. Releasing lab testing is performed on each batch of product that we manufacture in USA.
