When sourcing Centella Asiatica Extract, the price is primarily driven by the active ingredient concentration. You must verify the levels of Total Triterpenes, specifically Asiaticoside, Madecassoside, Asiatic Acid, and Madecassic Acid. High-purity extracts (e.g., 95% or 98% Titrated Extract of Centella Asiatica - TECA) will command a significantly higher price than 10:1 ratio extracts. Always request a Certificate of Analysis (COA) and verify the testing method, preferably HPLC (High-Performance Liquid Chromatography), to ensure the potency matches the quoted price.
