More testing is in order. Next, the herbs next undergo High Performance Liquid Chromatography (HPLC). This test assures that each herb is at its maximum potency and effectiveness and is performed on all pharmaceuticals.
Further testing to ensure safety are performed to make sure Herbsmith herbal blends meet the highest standards for purity and safety. When arriving in the U.S. for manufacturing, they are also reviewed by the U.S. Food and Drug Administration for approval.
Safety is priority number one at Herbsmith. They only work with manufacturers that comply with the strict Chinese Good Manufacturing Practices (GMP) and have been certified by the Australian Therapeutic Goods Administration (TGA), which maintains some of the highest standards in the world. In addition, they receive certificates of analysis from independent laboratories for every batch of herbs that go into their herbal blends.
