Echinacea angustifolia, also known as purple coneflower, comes from the group Dicots and from the family AsteraceaeEchinacea angustifolia has white leaves with orange-like buds and leaves that have a frost-like appearance to them.

Native to the U.S., Echinacea angustifolia is neither a threat nor is it considered threatened (meaning it is not an invasive species nor is it considered endangered). Its habitat includes grasses, shrubs, forbs (a broad-leaved herb), and trees.

A commonly used herb to relieve or allay pain.  It is considered an antiseptic, a form of treatment for poisionous insect and snake bites, and a cure for toothaches and sore throats. The Lakota used Echinacea angustifolia for cases of thirst and perspiration as well as using the seed heads for combing their hair. Modern day uses of Echinacea angustifolia include its uses in stimulating the immune system and as a preparation against colds and flu.

One of Echinacea angustifolia's active ingredients is polyphenol. Polyphenols are a group of chemical substances found in plants. Popular belief claims that polyphenols may reduce the risk of cardiovascular disease and cancer.
