Cranberries have long been studied in supporting a healthy urinary tract. Cranberries contain compounds which inhibit the bacteria from attaching to the bladder wall, washing the bacteria away in the normal cleaning process of the urinary tract.
Cranberry tea can also be used to overcome asthma attack. The berries contain an active ingredient similar to that in the drugs used to control asthma. (Please consult your doctor before using any teas for medicinal purposes.)
