Herbsmith Chinese Herbs are made of the highest quality ingredients and quality-tested in the U.S. to ensure purity, authenticity, and safety with some of the most stringent testing and manufacturing guidelines in the world.

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 and allows Herbsmith 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. Herbsmith then tests every batch of herbs for moisture content, dissolution, heavy metals (lead, arsenic, mercury, cadmium) and microbial content, 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.

Herbsmith Chinese Herbs are very high quality herbal products and we feel very proud to offer them to our customers for the good health and well-being of their pets.
