For centuries, plant juices and extracts have been used for their curing and medicinal properties. Juice therapy uses the fresh, raw juice of vegetables and fruits to nourish and replenish the body. It can also be used as part of a thorough health maintenance plan.

  Juice therapy offers a balanced way to supplement the diet, according to Steven Bailey, N.D., of the Northwestern Naturopathic Clinic in Portland, Oregon. "One of the most convenient therapies available is the use of raw fruit and vegetable juices to augment the typical diet. Juice can also aid in a patient's treatment program by stimulating the immune system, reducing blood pressure, aiding in detoxification, and protecting the body from harmful environmental factors. It is also used to help diagnose and treat food allergies, and is the ideal nutritional remedy for individuals suffering from nausea or digestive problems."
