Echinacea is an herb. Several species of the echinacea plant are used to make medicine from its leaves, flower, and root.

Echinacea is widely used to fight infections, especially the common cold and other upper respiratory infections. Some people take echinacea at the first sign of a cold, hoping they will be able to keep the cold from developing. Other people take echinacea after cold symptoms have started, hoping they can make symptoms less severe. The people who use echinacea to treat symptoms have the right idea. Research to date shows that echinacea probably modestly reduces cold symptoms, but it’s not clear whether it helps prevent colds from developing.

Echinacea is also used against many other infections including the flu, urinary tract infections, vaginal yeast infections, genital herpes, bloodstream infections (septicemia), gum disease, tonsillitis, streptococcus infections, syphilis, typhoid, malaria, and diphtheria.

Other uses not related to infection include chronic fatigue syndrome (CFS), rheumatism, migraines, acid indigestion, pain, dizziness, rattlesnake bites, and attention deficit-hyperactivity disorder (ADHD).


Sometimes people apply echinacea to their skin to treat boils, abscesses, skin wounds, ulcers, burns, eczema, psoriasis, UV radiation skin damage, herpes simplex, bee stings, and hemorrhoids.

Echinacea species are native to North America and were used as traditional herbal remedies by the Great Plains Indian tribes. Later, settlers followed the Indians’ example and began using echinacea for medicinal purposes as well. For a time, echinacea enjoyed official status as a result of being listed in the US National Formulary from 1916-1950. However, use of echinacea fell out of favor in the United States with the discovery of antibiotics and due to the lack of scientific evidence supporting its use. But now, people are becoming interested in echinacea again because some antibiotics don’t work as well as they used to against certain bacteria.

Commercially available echinacea products come in many forms including tablets, juice, and tea.

There are concerns about the quality of some echinacea products on the market. Echinacea products are frequently mislabeled, and some may not even contain echinacea, despite label claims. Don’t be fooled by the term “standardized.” It doesn’t necessarily indicate accurate labeling. Also, some echinacea products have been contaminated with selenium, arsenic, and lead.

Studies on the effectiveness of echinacea at preventing or shortening colds are mixed. Some studies show no benefit. Others show a significant reduction in the severity and duration of cold symptoms when taken in the early stages of a cold. One reason study results have been inconclusive may be that the type of echinacea plant and preparation used from one study to the next have varied considerably. Research on the role of echinacea in treating the common cold is ongoing. In the meantime, if your immune system is healthy and you aren't taking prescription medications, using echinacea supplements is unlikely to cause harm.
