Herb Pharm prepares Black Elderberry Glycerite from the ripe berries of Certified Organic Sambucus nigra trees. The berries are hand-harvested only when ripe to assure optimal extraction of Black Elderberry'™s bioactive compounds. 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.
