Its immunomodulatory properties have been extensively studied, and numerous preclinical and clinical studies have demonstrated its efficacy in enhancing immune responses against bacterial and viral pathogens.
  • Several in vitro studies have demonstrated the antiviral activity of Echinacea extracts against a range of viruses, including influenza virus, herpes simplex virus (HSV), and human immunodeficiency virus (HIV).
  • Several studies have demonstrated the antibacterial activity of Echinacea extracts against a wide range of bacteria, including Staphylococcus aureus, Escherichia coli, and Streptococcus pneumoniae. The active compounds responsible for this activity are believed to be alkamides, polysaccharides, and caffeic acid derivatives.
  • Several studies have demonstrated the antioxidant properties of Echinacea extracts. For example, a study by Lee et al. (2013) showed that Echinacea purpurea extract significantly reduced oxidative stress in human lung epithelial cells.
