Echinacea
genus of plants, used for centuries as medicine
Echinacea [ek-in-NAY-shee-a] is a genus of herbaceous flowering plants in the daisy family. It has ten species, which are commonly called coneflowers. They are native only in eastern and central North America, where they grow in wet to dry prairies and open wooded areas. They have large, showy heads of composite flowers, blooming in summer. The generic name is derived from the Greek word ἐχῖνος (ekhinos), meaning "hedgehog", due to the spiny central disk. These flowering plants and their parts have different uses. Some species are cultivated in gardens for their showy flowers. Two of the species, E. tennesseensis and E. laevigata, were formerly listed in the United States as endangered species; E. tennesseensis has been delisted due to recovery and E. laevigata is now listed as threatened.
Echinacea has a long history of use in traditional medicine by Indigenous peoples for treating infections, pain, and wounds, and it later gained popularity in Western herbal remedies, especially for colds. However, modern research shows weak or inconclusive evidence for its effectiveness, with concerns about product variability and potential side effects.
The public source identifies “Echinacea” as genus of plants, used for centuries as medicine. This brief keeps that definition visible, then builds a research path around Echinacea, genus and plants.
Why this record matters
A short description can identify a subject without explaining its stakes. For “Echinacea”, the useful work is to connect “genus of plants, used for centuries as medicine” to the records capable of establishing context and consequence.
Stable identifiers, scientific names and standards terminology offer the best bridge between this overview and specialist evidence. The source revision retrieved here is dated Sep 11, 2026. The linked authority identifier is Q1642983. The Library of Congress control number is sh90005852. 1 of 1 selected statements include explicit references; 1 carry qualifiers and 0 use preferred rank.
Current terminology should not be projected backward without checking the classification used when the underlying evidence was created. The source lead contains qualifying language; that uncertainty should survive quotation, summary and reuse. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
How to read it
