Although safety in pregnancy has not been categorically established, results from a prospective study of 206 women who had inadvertently taken echinacea during their pregnancy found that gestational use is not associated with an increased risk for major malformations (Gallo et al 2000). Oral use of echinacea is considered safe in pregnancy when used in recommended doses (Mills & Bone 2005).
