Echinacea is the name of a group of flowering plants in the daisy family.
Altogether, this group has nine species, but only three are used in herbal supplements — Echinacea purpurea, Echinacea angustifolia and Echinacea pallida.
Both the plant’s upper parts and roots are used in tablets, tinctures, extracts and teas.
Echinacea plants contain an impressive variety of active compounds, such as caffeic acid, alkamides, phenolic acids, rosmarinic acid, polyacetylenes and many more.
In addition, studies have linked echinacea and their compounds to many health benefits, such as reduced inflammation, improved immunity and lower blood sugar levels.
