All herbs are manufacturer-tested using Thin Layer Chromatography (TLC) and High Performance Liquid Chromatography (HPLC) to confirm identification, ensure potency and to test for active constituents when necessary.

Kamwo partners with Advanced Laboratories, an independent third-party US laboratory, to ensure the safety and quality of our herbal products. Advanced Laboratories is ISO IEC 17025 accredited and FDA registered, providing validated analytical testing for dietary supplements and botanicals. Our herbs are tested for microbial contamination, heavy metals including Arsenic, Lead, Mercury, and Cadmium, as well as a broad panel of pesticide residues in accordance with USP standards.

Through voluntary testing and by sourcing sulfur-free medicinals whenever possible, we are committed to raising industry standards and ensuring that every patient receives herbs of the highest quality and safety.
