What is Echinacea?

Echinacea is an herb derived from a flowering plant known as the American coneflower. Echinacea is part of the daisy family known as Asteraceae and is native to North America. There are ten species of echinacea, which are found exclusively in eastern and central North America including the United States. Three species—Echinacea purpurea, Echinacea pallida and Echinacea angustifolia are the most commonly used in herbal medicines.

The herb has been used as a natural remedy for hundreds of years by Native American tribes including the Great Plains Indians. The roots, flowers, leaves, and stems are all used to make herbal supplements and natural cures. The different species can be distinguished by either a yellow or purple coneflower as well as different leaf structures.

Echinacea herbal medicine vary depending on the species of echinacea used as well as the plant parts incorporated into the medicine. Echinacea essential oils and echinacea extracts can be cold pressed from leaves and flowers.

While the herbal supplements may vary, most offer the same basic health benefits. There is evidence to suggest that Echinacea plant parts above the ground are more powerful health agents than root systems. That's because echinacea leaves and stems are packed with polysaccharides and vitamin C. Most echinacea extracts thus are made using the leaves and stems.

In Europe, including Germany and the United Kingdom, many organizations caution against echinacea use in children. The Medicines and Healthcare Products Regulatory Agency (MHRA) advises parents not to give children under the age of 12 echinacea products.

The main concern is that children can develop serious allergic reactions to the plant products more easily than adults. Avoid using echinacea on children under 12 to be safe.
