Echinacea Purpurea: A Promising Natural Remedy for the Common Cold

Summary: A study by the University of Alberta highlights the benefits of Echinacea purpurea extracts in reducing common cold symptoms. With 150 volunteers participating, the study observed that an initial increase in cold symptoms was followed by a reduction in severity over time. Blood samples indicated a significant change in immune cell composition, with increases in neutrophils and monocytes and a decrease in lymphocytes. Echinacea may stimulate immune cells to produce endogenous antioxidants, aiding in initial defense against pathogens. Meta-studies indicate Echinacea, especially when combined with vitamin C, can lower the risk of colds. The findings support Echinacea as a potential natural remedy to bolster immune health during viral infections.
