History

Echinacea angustifolia rhizome was used by North American Plains Indians, perhaps more than most other plants, for various herbal remedies. Echinacea was one of the basic antimicrobial herbs of Eclectic medicine in the mid 1800s through the early 1900s and its use was documented for snakebite and anthrax. In the 1930s "Echinacea" became popular in both Europe and America as a herbal medicine.

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. The alkamides, polysaccharides, and chicoric acid are most oftenrecognized for their immune-modulating effects. The concentration of these constituents depends on the species, the plant parts used, and the method of extraction.

Alcohol-based or dry

Leading herbalists claim that many studies do not distinguish between alcohol-based echinacea tinctures, which retain potency for up to seven years after production, and capsules containing the dried herb, which lose their efficacy over time.

Capsules not only lose strength, but must be digested in the stomach while alcohol tinctures enter the lymphatic system through the tongue.

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.

Species

Not all species of Echinacea are equally effective. A Cochrane review of the published studies has found that there is some evidence of benefit in the treatment (but not prevention) of the common cold by the aerial parts of Echinacea purpurea; other formulations of the plant did not show the same effect, and no formulation was effective for prevention.

Echinacea purpurea alkylamides in acting as a prophylactic against the cold virus, along with previous recent research supporting its effective use in supporting the immune system against cold virus symptoms

Several studies of the studies presented have used the freshly harvested Echinacea purpurea preparation

Mode of action of Echinacea deciphered

Research has identified alkylamides as important active ingredients in Echinacea, as well as their mode of action in vitro and in vivo. The substances latch on to the immune cell's endocannabinoid receptors and thereby activate the immune system. The mixture used here, composed of 5% root and 95% stem, leaves and flowers, has proven to be efficacious in numerous comparative studies.

Prevention and treatment of colds

A meta-analysis of all in-vivo clinical research studies regarding the mode of action, prevention and treatment of colds with Echinacea are showing a new picture: those who took Echinacea as a prophylactic treatment had, during the cold season, more than 50% less risk of catching a cold compared to those who did not take Echinacea. Products with alcohol extracts of Echinacea have shown better results compared to juices.
