Here's a fresh juice recipe that will help you shake off holiday indulgences and start clean. This recipe is made from an array of ingredients that have natural detoxing properties: watercress helps energize cleansing enzymes in the liver, and, like celery, it's a natural diuretic. Antioxidant-rich spinach boosts chlorophyll levels in the digestive tract, which helps the body get rid of environmental toxins. Lemon is a great source of vitamin C and helps alkalize the body. Spicy ginger aids digestion. And besides giving a boost of vitamins, apples add just enough natural sugar to mask the earthy taste of the greens. This juice is bound to become part of your daily ritual.
