Fresh Echinacea extract and essential oils A.Vogel’s Echinacea toothpaste contains extracts of freshly harvested herbs and essential oils in an all natural base. It is non-abrasive, cleans thoroughly and will leave your mouth feeling fresh. Liquorice, another ingredient in this toothpaste, has a distinct sweet taste often associated with confectionary. The roots of liquorice are chewed to freshen breath naturally. Other herbs in the toothpaste give it an astringent and refreshing taste. Tragacanth gum is a water soluble mixture of polysaccarides obtained from the sap of the Astragalus gummifer plant. It is tasteless and odourless and is useful for binding the herbs together.
