Echinacea refers to a group of flowering plants, commonly known as coneflowers, native to North America. These plants have been used for centuries in traditional medicine, particularly by Native American tribes, and are now widely recognized as a popular herbal supplement.
As a supplement, Echinacea is primarily taken to support the immune system. It is available in various forms, including capsules, tablets, liquid extracts, and teas. People often use it at the first sign of a cold or flu, believing it can help boost the body's natural defenses.

Additionally, Echinacea has been traditionally applied topically for skin conditions such as minor wounds, burns, and insect bites. It is believed to possess anti-inflammatory and wound-healing properties that may aid in the skin's natural recovery process.
Common forms include standardized extracts, which are thought to concentrate the active compounds, and whole-plant preparations. The root and aerial parts of the plant are typically used, with different species like Echinacea purpurea and Echinacea angustifolia being most commonly utilized.
