Perhaps the most famous herbal remedies these days are made from the Echinacea flower. Native Americans have traditionally used Echinacea to treat colds, fevers, snakebites, and stubborn wounds. It is believed that the early settlers adopted the Echinacea plant early on as a popular home remedy to treat colds and influenza. The plant was a popular choice with the 19th century Eclectics. In recent years, Echinacea has grown immensely in popularity for its antiviral, antifungal, and antibacterial properties. Echinacea has also been used in AIDS therapy. The cultivated purple coneflower is known as E. purpurea, but E. angustifolia is generally considered to be the more potent version by most herbal practitioners. The character of Echinacea has alternately been described as cool, dry, and strongly pungent. Its constituents include volatile oils, glycosides, antibiotic polyacetylenes, amides, and insulin. The actions of the Echinacea plant are described as antibiotic, an immune stimulant, antiallergenic, and a lymphatic tonic.

Several parts of the Echinacea plant are used to create herbal remedies, but the most common parts that are used are the root and the aerial parts. The root of the Echinacea flower is most commonly used to make tinctures or powders. These tinctures and powders are used to treat many different types of infection or inflammation. Many traditional herbalists have used Echinacea to treat recurring kidney infections, as well as to treat less serious conditions including the common cold, influenza, and cold and respiratory infections. The aerial parts of the Echinacea flower are often used to make an effective antibiotic. These are usually taken in capsule form.
