Echinacea /ËÉkÉ¨ËneÉªÊâ±É/ is a genus, or group of herbaceous flowering plants in the daisy family. The Echinacea genus has nine species, which are commonly called purple coneflowers.They are found only in eastern and central North America, where they are found growing in moist to dry prairies and open wooded areas. They have large, showy heads of composite flowers, blooming from early to late summer.ome species are cultivated in gardens for their showy flowers. Echinacea purpurea is used in folk medicine. Two of the species, E. tennesseensis and E. laevigata, are listed in the United States as endangered species.
There is not enough information to know if echinacea is safe for long-term use. Some side effects have been reported such as fever, nausea, vomiting, unpleasant taste, stomach pain, diarrhea, sore throat, dry mouth, headache, numbness of the tongue, dizziness, insomnia, disorientation, and joint and muscle aches. Evidence on the effect of echinacea for the treatment of HSV is unclear. 2  Some research shows that taking a specific echinacea extract (Echinaforce by Bioforce AG) 800 mg twice daily for 6 months does not seem to prevent or reduce the frequency or duration of recurrent genital herpes.
