Echinacea purpurea (Purple Coneflower )should be of particular interest during the cold and flu season when you are exposed to these illnesses on a regular basis. When used correctly it is the closest thing to a cure for the common cold. Echinacea purpurea stimulates the overall activity of the cells responsible for fighting all kinds of infection. Unlike antibiotics, which directly attack bacteria, Purple coneflower makes our own immune cells more efficient at attacking bacteria, viruses and abnormal cells, including cancer cells. It increases the number and activity of immune system cells including anti-tumor cells, promotes T-cell activation, stimulates new tissue growth for wound healing and reduces inflammation in arthritis and inflammatory skin conditions.
