The body is built to detox itself...The problem lies when the body is being hit by every angle...From the water we drink, the air we breathe, the food we eat and the medicine/drugs we put in our bodies...The liver and kidneys can only do so much...Over time they take there toll...Detoxing the body and giving the digestive system a "semi" break(It never stops working)...It can take a sluggish liver/kidneys back to normal with only a few days of dextoxing...If you're using hormones, then detoxing your body should be something that is done atleast twice a year...
