Echinacea
Echinacea 
Echinacea 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. 
Pregnancy 
Although research has not found increased risk of birth defects associated with use of echinacea during the first trimester, it is recommended that pregnant women should avoid echinacea containing products until stronger safety supporting evidence becomes available.[12]
Lactation 
It is recommended that women breastfeeding should use caution with echinacea products due to insufficient safety information available.[12]
General precaution 
The U.S. Food and Drug Administration recommends precaution about using dietary supplements because some products may not be risk free under certain circumstances or may interact with prescription and over-the-counter medicines.[22]

As with any herbal preparation, individual doses of echinacea may vary significantly in chemical composition. Inconsistent process control in manufactured echinacea products may involve poor inter- and intra-batch homogeneity, species or plant part differences, variable extraction methods, and contamination or adulteration with other products, leading to potential for substantial product variability.
