All of the herbs that go into our formulas pass strict quality control testing at one or more GMP certified facilities. Good Manufacturing Practices (GMP) help ensure the quality and safety of products, traceability of ingredients, and transparency of the manufacturing process. GMP certification means that the site and methods employed in production have been subject to a thorough quality control investigation by a government agency or qualified third party organization and are certified to be in compliance. Extensive quality control analysis is performed at each of the GMP certified facilities of our manufacturing partners to confirm identification and ensure safety, purity and potency. In accordance with Dietary Supplement GMPs, each lot received into our Chinese herb supplier’s warehouse is first quarantined. Then each product is sampled, the Certificate of Analysis verified, and the sample is compared with past lots for consistency. Herbs are inspected using sensory protocols, and confirmed against standard references if necessary to verify  quality and species. Herbs are sourced from their indigenous regions, ensuring geo-authenticity and quality, and usually come direct from the growers and harvesting co–ops to our supplier. Upon receipt, each herb is inspected to ensure correct species identification, proper maturity, and quality.
