Echinacea was first used in the mid-19th century. It was "one of the basic anitmicrobial herbs of eclectic medicine" (Echinacea. (n.d.) Retrieved January 8, 2012 from the OLPC Wiki: At that time, it was used for the relief of pain, snakebites, burns, insect bites and throat infections. The root of Echinacea was also chewed to ease the pain of tooth aches. It was also used by other tribes as an analgesic and was said if hands were washed with Echinacea, it would increase the tolerance of heat (Echinacea. (n.d.). Retrieved January 8, 2012 from Encyclopedia: It was first marketed back in the 1800's. The name of Echinacea became "Meyers Blood Purifier" (Echinacea. (n.d.) Retrieved January 8, 2012 from the OLPC Wiki: A man from Switzerland whose job was to make herbs, announced that Echinacea was used to treat colds by the Native Americans who occupied South Dakota. It became popular because people were attracted to it's supposive wide range of medicinal purposes and the history behind it. It is widely used as an over the counter product in Germany and is currently building its popularity in the U.S. to become one of the most purchased herbal remedies.

Medicinal purposes

As of today, Echinacea is well known for colds. Some studies show and the true believers in Echinacea, say that it boosts the body's immune system. It stimuates the macrophages which are part of the immune system cells. The macrophages attack invaders such as cancer cells. It is said to stimulate the white blood cells, which are the good cells of the body that can help fight certain diseases. Sometimes Echinacea is combined with Goldenseal (another herbal supplement) or any other kind of herb that contains berberine (herb that contains properties that help fight vaginal yeast infections). With the information of Echinacea and the many studies that have unknown outcomes with this herb, comes controversy.
Colds are a virus and cannot be treated with antibiotics. This could be why some cold sufferers turn to herbal remedies to lessen the duration of the cold. It seems that Echinacea is hard to compare it's effects, due to the fact that there are more than one kind of plant and all parts are used differently. According to The Nelison Co. "Americans spent $5.3 billion on cold and cough remedies at major U.S. stores in the year ending November 27." (Eric Risber AP (2010,12, 20). Got a Cold? Studies say Echinacea won't help much. Retrieved from With the amount of money that American's are spending on this product, a research project went into finding out if the product in the bottle really contained Echinacea and it's cold fighting qualities. It was actually found that one out of every ten bottles that was distributed, there was no trace of Echinacea.
In favor of Echinacea, another study done by the University of Conneticut, they came to the conclusion that Echinacea may only shorten the duration of a cold and possibly cut your chances of catching a cold in half. Other studies of this plant do show a lot of healing properties, all having different levels of how they will work. In a study combining those participants that took echinacea and those that were given a placebo, the results together explained that "echinacea reduced the risk of catching a cold by 58%. It also found that the herb significantly shortened the duration of a cold, but there was no general agreement about the magnitude of this effect." (Nicholas Bakalar (2007, 7,24).

Risks/Side effects

As with most herbal supplements, there may be side effects, or if taken in large doses, detremental to one's health. Echinacea is not supposed to be taken when a woman is pregnant or lactating. There has not been a single one case of real side effects when echinacea has been used that is fully proven. "Injections or oral dosage forms are to be used cautiously in diabetes mellitus because of fears that immunostimulants may adversely affect a patients metabolism."( Foster 1991). Since echinacea is known to stimulate immune function, it could possibly have a risk of decreasing the effectiveness of immunosuppresive drugs. It seems that if there are any side effects such as, nausea, diarrhea or abdominal pain, it could just as well coincide with the ailment than with Echinacea. However, no real evidence has been proven as of today that could be detrimental or fatal to a person.
