Avoid coffee, alcohol, and artificial drinks. Drinking unsweetened cranberry juice and apple juice helps reduce bacterial growth in the kidneys. Carrot, celery, and parsley juice is also helpful. Eat nourishing food, and avoid processed and junk food. Include enough vitamins C, A, and B complex in the diet.
Potassium deficiencies can encourage kidney problems.
Take enemas and rest. Keep the fluid level high. Helpful herbs include garlic, echinacea, burdock, red clover, and goldenseal. Buchu tea and marshmallow tea are most helpful. Used in conjunction with more fluid intake, corn-silk tea has been used for hundreds of years to increase urine output, a very necessary factor in purifying and detoxifying the kidneys.
