I am not a medical practioner, however this is what worked for my IBS.
First, go to the health food store and buy FOOD GRADE DE, diatemaceous earth. Mix 2 tablespoons with 1/2 cup water. Drink it down - tastes chalky, but this will rid your colon of any parasites. Do the research for FOOD GRADE DE, it helps cleanse your entire system.
Next, buy a good PROBIOTIC and DIGESTIVE ENZYME. Take as suggested.
***ALOE VERA JUICE - 2 or 3 Tablespoons, I mix with 1/2 cup water and again drink it down, two or three times a day. Aloe Vera juice is VERY healing.
To your health!
