To comply with FDA regulations, Treasure of the East developed a specialized bar coding system. Herbs distributed are controlled with a barcode scanning and tracking system which can be traced back to the original source of raw materials and finished product samples at Tianjiang Pharmaceutical.This allows practitioners to track every single herb to its original identification from the manufacturer. It records the information of production date, batch number, test results, and tracks herbs to their original batch samples. Every batch of the single herbs comes with the product's Certificate of Analysis (COA).
