Herb Pharm prepares Skullcap extract from fresh (never dried) Certified Organic Scutellaria lateriflora plants grown on fields they farm in southern Oregon. The plants are harvested while in full-flower, then promptly extracted 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.
