Herb Pharm Herb Pharm Blue Vervain Extract Supplement, 1 Ounce
We prepare our blue vervain extract from the flowering tops of verbena hastata and lasiostachys plants which are custom wild crafted in their natural wild habitat. To assure optimal extraction of blue vervain's bioactive compounds, the uppermost tops of the plants are hand-harvested only when in full flower. Our blue vervain is never fumigated or irradiated. Liquid herbal extract.
