There are 9 different species of Echinacea, the most commonly used in medicine are Echinacea angustifolia, Echinacea pallida and Echinacea purpurea. These three species differ in the color of their flowers: E. angustifolia’s flowers are mauve, E. pallida has white flowers, and E. purpurea’s ones go from pink to purplish-red. They also differentiate from each other by their leaves. E. purpurea has serrated, lanceolate, oval-shaped leaves; on the other hand, the other two leaves are not lanceolate. According to some authors, E. purpurea is more active in the test tubes and E. angustifolia more effective in people. The whole plant is gathered when blooming, even though the most important part is the root.
Echinacea angustifolia: the root and rarely the entire plant.
Echinacea purpurea: aerial parts and sometimes the root.
