Echinacea angustifolia is well known in traditional botanical medicine for its benefit to the immune system. Studies have demonstrated Echinacea's 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.

Ligusticum porteri is used in Chinese medicine for its notable immuno-stimulating effects.

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.

we have not had a cold or flu since starting Phytogen.

by Sue

Phytogen was recommended by our pharmacist when asked what to take if you felt like you were getting a cold or flu. He told us this was the ONLY thing they would recommend since that is what all the pharmacist take when around sick people all the time. We have not had a cold or flu since we started taking this. One every morning and two if we feel like we are coming down with something or around sick people. Won't be without it !!!

Great immune booster

by Delarivier

I've found Undecyn to be better at fighting off infection in cold& flu season than taking just echinacea alone.

KEEPING THE ""BAD BUGS"" AWAY...

by Barbara -

These capsules are wonderful. I work at the concierge desk of a large hospital/medical center. Lots of germs and viruses and other bad bugs come my way... Sometimes several days later I occasionally feel like I might be ""coming down"" with one of them... I take one of two Phytogen with plenty of water and by the next day I am fine again. I have been using this product for 7 years now and have not had a cold or other illness or missed a day of work. I LOVE IT !!!
