How it works

A virus is a tiny strand of genetic material inside a protein shell. Because it is not a living cell, a virus needs a host to survive. When viruses invade an animal, they penetrate the host’s cells and use them to replicate. In the process, they damage or destroy the cells. The immune system recognizes these viruses as invaders and fights them.

Certain plants contain compounds that increase the immune system’s response. The active compounds in echinacea stimulate phagocytosis, the process by which white blood cells destroy foreign invaders, including bacteria and viruses. Astragalus (Astragalus membranaceus) enhances the activity of natural killer (NK) cells that rapidly respond to viral infection. Lomatium (Lomatium dissectum) contains compounds called furocoumarins that disrupt the ability of viruses to replicate. Reishi (Ganoderma lucidum) inhibits viruses from attaching to and penetrating host cells. Beta-glucans derived from reishi enhance the function of many immune cells, including monocytes, macrophages, dendritic cells, neutrophils, and NK cells. Licorice (Glycyrrhiza glabra) contains glycyrrhizin and glycyrrhetinic acid, with immune-stimulating and anti-inflammatory properties.

Astragalus, reishi, and licorice all induce production of interferon, a signalling protein that triggers the immune system to attack infected cells and interferes with the ability of viruses to replicate.

Suggested Use

Anti-Viral from Natural Factors contains ECHINAMIDE®, the only standardized extract of Echinacea purpurea shown in placebo-controlled clinical trials to reduce the duration and severity of upper respiratory infections. ECHINAMIDE is made from certified organic echinacea grown on Factors Farms in BC’s Okanagan Valley. It is manufactured using highly sophisticated, proprietary EnviroSimplex® processing, which preserves the key actives responsible for echinacea’s effectiveness. Three key active compounds are isolated, concentrated, combined inthe ideal clinically proven ratio, and delivered in a base of the whole herb so that none of the minor actives are missing.

Herbal medicines are known to work best in combination. Anti-Viral contains a proprietary blend of ECHINAMIDE, lomatium, astragalus, reishi, and licorice. Modern science has confirmed that each of these herbs enhances the immune system’s response to viral infections. 

Anti-Viral stimulates the non-specific immune system to effectively fight every viral condition, from colds to herpes. It is available as a liquid tincture, or as an alcohol-free extract in a softgel.
