Echinacea has a
rich tradition of use by North American Plains Indians
who used it medicinally more than any other plant. Echinacea
helps to support immune health by increasing the activity
of our own immune cells, and so strengthens our immune
defence. Active ingredients from the plant are thought to fight colds, flu, and other infections.
Echinacea's activity is thought to be due to polysaccharides
contained in the root.
Echinacea is especially popular during certain seasons
where it is used to help ward off the winter cold.
