Echinacea Myths for Immune System Support

Echinacea purpurea should be combined with E. augustifolia

Echinacea has traditionally been used for hundreds of years, partly due to the thought that it benefits the immune system and protects against colds and infections. However, research has showed mixed results and there has been much confusion and misunderstanding of how Echinacea may provide health benefits. The following myths and explanations take a closer look at how Echinacea should or should not be used.

Prevention not Cure

Studies have demonstrated Echinacea may have more potential to support a healthy immune response when taken preventively rather than during an acute illness. While it may be helpful when taken during an infection, Echinacea's greater potential appears to be as a preventive measure to prepare the immune system before an infection occurs.

Echinacea & Long-term Use

Concerns regarding long-term use of echinacea have been dispelled by research that shows Echinacea is not only safe when taken over a year, but beneficial. A study in mice fed Echinacea daily for 13 months, showed increased health and longevity compared to mice not fed Echinacea. Other studies have indicated potential benefit when taken by those with chronic immune system issues.

Purple Coneflowers are Echinacea?

It's important to recognize the various species of Echinacea and their varying ability to effect immune system function. The purple coneflowers frequently grown in gardens (pictured above) are one species called Echinacea purpurea. Another species called Echinacea augustifolia has more traditionally been used, and research indicates its roots contain higher levels of alkylamides that are the primary active constituent. It's the alkylmides that cause a tingling sensation on the tongue when taken.

Studies indicate E. augustifolia root or a blend of both species are more effective for immune support. If your supplement doesn't cause a mild tingling when held in the mouth, it may be too low in active constituents to be effective. Studies that have found less benefit with Echinacea, tend to use the wrong plant, the wrong part (not the root), the wrong method of concentration, or too small a dose.

How Does Echinacea Effect the Immune System?

Research has demonstrated multiple changes in immune cell function with Echinacea. Research has noted significant increases in natural killer cells and monocytes. Natural killer cells are important in defending against viruses, by killing virus-infected cells in the body. Monocytes are a type of white blood cell that can capture microorganisms or transform into macrophages that "eat" fungi and microbes. There also appears to be beneficial effects on T cells and heat shock proteins that play a role in a healthy immune response.

In a study of adults flying internationally in economy class, those taking Echinacea Premium tablets before, during, and after flight experienced fewer symptoms of respiratory illness compared to the placebo group.

Echinacea is worth considering as part of a healthy lifestyle to support proper immune system function. Our preferred version is Echinacea Premium due to its high quality and research support. Those with allergies to the daisy family should be cautious, though there is less concern when the root of the plant is used.
