Herb Pharm prepares Echinacea Glycerite from the Certified Organic root of Echinacea purpurea plants. To assure optimal extraction of the herb'™s bioactive compounds, they harvest the roots during the autumn and promptly extract them while still fresh and succulent. All their Glycerites are made using 100% non-palm glycerin to avoid contributing to global rainforest deforestation. Instead of palm, they use Certified Organic corn glycerin. Herb Pharm assures herb identity via macroscopic and organoleptic analysis, then confirms it through methods such as HPTLC fingerprinting specific to each herb.
