Where do your herbs come from?
Our individual ingredients are sourced from China. Our herbs are sourced individually from specific providences of China because of optimal growing conditions (drainage to the soil, sun patterns, quality of the soil, etc.) For example, only the providence of Shanxi has grown astragalus for thousands of years because its conditions consistently provide the highest quality.However, each and every batch of herbs that we bring in to make our formulas is tested in the U.S. to ensure purity, authenticity, and safety.
What kind of safety measures do you take with your ingredients?
Each and every batch of herbs that we use to make our formulas is tested in the U.S. to ensure purity, authenticity, and safety. From the soil the herbs grow in to the finished bottles going out the door, we monitor every step of the process, using only proven, trustworthy suppliers, holding ourselves to the highest ethical standards and abiding by the most stringent testing and manufacturing guidelines in the world.To ensure that only the most authentic herbs go into Herbsmith herbal blends, all raw materials used in production are subjected to a battery of tests including Thin Layer Chromatography (TLC), a sophisticated means of identifying the makeup of individual substances in a given compound. This unique fingerprint confirms the chemical composition and authenticity of each and every herb we use and allows us to use only the most high - quality herbs available.The herbs next undergo High Performance Liquid Chromatography (HPLC), a test performed on all pharmaceuticals to confirm the consistency and concentration of the compound. This step assures that each herb is at its maximum potency and effectiveness.Further testing for moisture content, dissolution, heavy metals (lead, arsenic, mercury, cadmium) and microbial content are performed on every batch, including Aristolochic Acid and Chloramphenicol testing.When the products arrive in the United States for manufacturing, they are reviewed by the U.S. Food and Drug Administration to further guarantee that every element that goes into Herbsmith herbal blends meets the absolute highest standards for purity and safety.
