All Honso products are imported accompanying with a Certificate of Analysis (C of A) and filed at Honso USA as seen below for H48 All-Inclusive Great Tonifying Formula. Honso practitioner customers can request the C of A on products that they have ordered for their patients/clients with the lot number (printed on the product label). As a key measure, Honso C of A provides the specification on major chemical constituents and the HPLC test results as markers for quality control process (i.e. glycyrrhizin, paeoniflorin and cinnamic acid in H48 sampled below).
