Although many of these illnesses have been treated mainly by antibiotics lately, note that several of these viruses and bacteria are believed to be targets of terrorists. Thus, echinacea will be an important herb in the fight against
Echinacea has been shown to improve the first lines of defense of our body against disease especially from external bacteria and viruses. It does so by inhibiting an enzyme called hyaluronidase that can be stimulated by pathogens to break apart the connective tissue surrounding body cells (known as the reticuloendothelial system, or RES). Once the integrity of the RES connective tissues has been compromised, germs can easily latch onto body cells and begin the progressive destruction of cells. Substances in echinacea combine with receptors on hyaluronidase and neutralize it. This results in a temporary improvement in the skin's and other tissues' ability to keep the germs away.(3,4)
Echinacea constituents may also be involved in the regrowth of connective tissue that has been destroyed during infection. The stimulation of the healing process drastically reduces the degree to which sensitive and vulnerable body cells are exposed to an environment laden with dangerous microorganisms.
During the period of infection, when the body is running low on its resources, echinacea has been found to have a strong and direct activating force on the body's ability to produce macrophages and speed them to the area of infection. Echinacea also stimulates the production of the
Another way that echinacea augments immune system function is
by its ability to exhibit a significant lethal effect on certain forms of cancerous tissue. USDA researchers have isolated a tumor-inhibiting principle in the essential oil of echinacea. The herb may do this by stimulating the production of key lymphocytes which in turn trigger the activation of cells such as the natural killer cells that destroy the cancer. (7)
In 1978, researchers in Germany discovered that echinacea behaves in a manner similar to interferon, either by stimulating the production of interferon or by acquiring some of its characteristics. No one knows for sure how it works, but the findings are consistent:
Echinacea possesses a mild antibiotic property of its own against certain kinds of microorganisms, including strep and staph germs. (9, 10)
Echinacea is completely nontoxic. It is perfectly safe to use every day.
Echinacea is best taken as a concentrated liquid extract, or tincture. It is more easily absorbed into the bloodstream in liquid form. Using it in the form of an alcohol extract is reportedly more beneficial than in dry, capsule, or tablet form.
Some herbalists suggest that the immune benefits of echinacea are strongest when it is used no more than a couple of weeks at a time.
A German study, published in 1992, reported that 900 milligrams of echinacea significantly reduced flu symptoms. Lower doses, however, were no better than dummy pills. (12)
To treat an infection, take one-half to one teaspoon of echinacea as an herbal extract in liquid form three times daily for seven to ten days. Another method would be to take echinacea in homeopathic form. Take twenty drops as the first dose, and then take ten drops up to six times daily for two days. Then take ten drops three times daily for up to one week after overcoming the infection. For more serious infections, a homeopathic medicine called Echinacea compositum may be used.
You can use echinacea alone. But many herbalists recommend it in combination with other herbs.
