Fasting is great for cleansing the body. It gives the body a break so it can regenerate itself.
The kidneys do not tend to be as popular of an elimination organ to detox but it plays an important role in the body's health and detoxification.
The kidneys are responsible for filtering wastes and other toxins from your blood stream, so you can maintain homeostasis and a proper acid/alkaline balance. If your kidneys are not functioning correctly, they will not remove waste products and excess minerals and these toxins will build up in your blood.
This cleanse is created a highly acidic environment for bacterias to be flushed out.
As usual you would want to speak to a natural health practitioner to see if this is right for you and you would want to detox your organs in the proper order, but here are some reasons why you might want to do a Kidney Flush :
dry skin, skin rashes, hair loss,
inability to focus, fuzzy vision,
fatigue, lethargic feeling, drowsiness
heart palpitations, high blood pressure
incontinence, kidney stones, urinary tract infections
decreased urine flow, increased nightly urination,
burning or painful urination, dark colored urine
itching, sleep problems, metallic taste in mouth
nausea, coldness, fever
swollen joints, stiff neck, cramps
abdominal or lower back pain
poor appetite, diabetes, anemia
