American and Chinese botanical combination to promote optimal immune function*

• Echinacea helps activate natural killer cells*
• Coptis contains berberine, which can inhibit adherence of foreign organisms to the lining of the GI tract and bladder*
• Astragalus helps the body create more white blood cells*
• Schisandra has a long history of use in Chinese medicine for immune support, particularly in the respiratory tract*

Echinacea angustifolia is well known in traditional botanical medicine for its benefit to the immune system.* Studies have demonstrated Echinaceas ability to activate natural killer (NK) cells and enhance the ability of other cell types to engulf foreign substances.*

Berberine, a major alkaloid found in Coptis chinensis, has direct immune-supporting activity by inhibiting the adherence of foreign organisms to red blood cells and epithelial cells.*

Astragalus membranaceus, an important Chinese botanical, has a long history of use as a tonic and immunomodulator, probably due to its ability to naturally enhance white blood cell counts.* Currently, much of the research on Astragalus is focused on its immune-stimulating polysaccharides.*

Schisandra is recommended in the Chinese materia medica as being immuno-protective of the respiratory system.* It has been studied extensively in China and Japan for its immune-modulating effects.*
