Historical overview
Long before the coming of the European settlers, the native Americans used Echinacea (also called Purple Cone Flower) to treat a variety of problems, from infections to snake bites. In the United States, Echinacea was popularized by the eclectic physicians` movement in the 19th Century. After that, its use was almost forgotten until the 1980`s. In Europe, however, Echinacea was popular with the medical world from the beginning of the Century and has been the subject of numerous clinical studies. Today, Echinacea is the most widely sold medicinal herb in the world.
Actions and pharmacology
In vitro studies have allowed the discovery of Echinacea’s action mechanism: its polysaccharides and polyacetylenes fractions stimulate the phagocytosis of macrophages and the production of cytokines like interleukine-1, interleukine-6 (also called interferon beta), interleukine-10 and TNF alpha factor. This effect shows Echinacea’s ability to stimulate the immune system in cases of infection.(1)
Chicoric acid and analogues derived from caffeic acid are presently under investigation for their effect on HIV-1 replication.(2)
Echinacea, particularly the echinacosides and caffeic acid derivatives, might protect collagen structures against degradation (oxidation) caused by free radicals. This antioxidant effect is also useful to relieve the inflammation generated by the immune system during its fight against the viruses of colds.
