Our Mullein Garlic Oil is a proprietary blend of the extracts of Calendula flower (Calendula officinalis), St. John's Wort flowering top (Hypericum perforatum), Mullein flower (Verbascum sp.) and Garlic bulb (Allium sativum). All herbs are harvested at their optimal peak then promptly extracted in Certified Organic olive oil. The St. John’s Wort, Mullein and Garlic are extracted while still fresh and succulent while the Calendula is extracted after being carefully shade-dried.
