We prepare our Grindelia extract from the leaf & flower of Grindelia spp. plants which are Certified Organically Grown1 without the use of chemical fertilizers, pesticides or herbicides or are Custom Wildcrafted™ in their wild native habitat in California's Sierra Nevada Mountains.
To assure optimal extraction of Grindelia's bioactive compounds, the plants are hand- harvested in mid-summer, are carefully shade-dried to retain their full color and aroma, and are then thoroughly extracted.
Our Grindelia is never fumigated or irradiated
