Active substances

The full spectrum of echinacea's chemical components responsible for its health effects are not well understood. Like most crude drugs from plant or animal origin, the constituent base is complex and some parts may be directly antimicrobial while others work at stimulating or modulating different parts of the immune system. All species have chemical compounds called phenols, which are common to many other plants. Both the phenol compounds Cichoric and caftaric are present in E. purpurea, other phenols include echinacoside, which is found in greater levels within E. angustifolia and E. pallida roots than in other species. When making herbal remedies, these phenols can serve as markers to evaluate the quantity of echinacea in the product. Other chemical constituents that may be important in echinacea health effects include alkylamides and polysaccharides. Chemical constituents among echinacea species include the lipophilic fractions (e.g., alkamides and polyacetylenes), water-soluble polysaccharides, caffeoyl conjugates (e.g., echinacoside, cichoric acid, and caffeic acid), and flavonoids.

Immunostimulant effects

Echinacea is popularly believed to be an immunostimulator, stimulating the body's immune system and warding off infections,particularly the common cold. However, its clinical efficacy has not been established.
