FASTING a couple of days with gator aide, broth, AND A NATURAL DETOX COLON or LIVER CLEANSE IS THE ONLY WAY I KNOW OF. Be prepared to stay near the bathroom as you will use it often. Make sure you have plenty of TP in the bathroom.
Half your immune system is in your GI Track, both small and large intestines. As I have Colitis Ileus, my food moves very slow through my GI Track and causes extreme pain I take a natural colon cleanse just to go to the bathroom. I use the Natural Colon Formula, at less than the needed dosage, just enough to get the colon to empty daily. Sure beats the Miralax and laxatives cramping, more control too.
Here is a good place to look, prices are reasonable. Products do work. I get a lot of my bone vitamins and minerals from them. They often have BOGO sales and free shipping.
Be sure to read labels as to the amount of tabs, caps etc you need to take. Read reviews!
