Supports and helps maintain your dog's natural, healthy immune defenses*

• Andrographis herb (Andrographis paniculata): A tropical and subtropical herb that has been used in Traditional Chinese Medicine for many hundreds of years, Andrographis is receiving increasing interest in the West. Studies have isolated an antiviral component and also some activity against the herpes virus. In traditional use, it has been employed for the liver, stomach, and to induce normal appetite.
• Echinacea root (Echinacea angustifolia): Echinacosides and polysaccharides in Echinacea have been the subject of numerous studies for immune system support. Echinacea has been shown to exert an antiviral effect by stimulating an immune response rather than directly affecting a virus itself. Echinacea has also been shown to increase white blood cell counts and initiate general immune response and resistance.
• Usnea thallus (Usnea barbata): Also called "Old Man's Beard", constituents isolated from Usnea lichen have shown an antimicrobial action against bacteria, viruses, and fungi.
• Goldenseal root (Hydrastis canadensis): Goldenseal is often indicated for a healthy immune system response when infection is present. It has been shown to have a direct antimicrobial effect on many bacteria and viruses.
• Elder berry (Sambucus nigra): Elder berries, high in flavonoids, have a long history of use for colds, influenza, fever, enlarged glands and tonsils, and sinus infection. Elderflower and berry have shown clinical effectiveness with its antioxidant and antiviral activity.
• Licorice root (Glycyrrhiza glabra): Numerous bioactive constituents have been found in Licorice with glycyrrhizic acid considered to be the most active. Pharmacological studies indicate antiviral, antimicrobial, anti-inflammatory and anti-oxidative activity. Licorice is also used as a natural sweetener due to its sweet taste.
• Propolis resin: This is an exudate collected from bee hives. Bees keep their hives protected from fungus and other life threatening microbes by sealing cracks in their hive structure with this substance. It is mainly collected from poplar trees and is considered a natural antimicrobial. When propolis is harvested, bees continue to make more for their hive.
• Ginger rhizome (Zingiber officinale): A small amount of ginger is added to this formula as a "harmonizer" and for its known antibacterial properties.
