Great plantain is a plant. The leaves and seeds are used to make medicine. Be careful not to confuse great plantain with buckhorn plantain, water plantain, or other similar-sounding medicines.
Great plantain is used for bladder infections, bronchitis, colds, and irritated or bleeding hemorrhoids. It is also used to kill germs and reduce swelling. Some people apply great plantain directly to the affected area for skin conditions or eye irritation.
