To keep your bowels moving: take 2-3 heaping tablespoons of ground flaxseeds in the morning in yoghurt. You can try activated H2 which i have just started and others here recommended to remove toxins and help w constipation. You put 1 pill in half a liter of distilled water and drink after 15 mins. Do it in the morning, away from food. Also oils help, like lots of olive oil on your salad, on your bread or puree soup. Coconut oil a tablespoon after eating. Spirulina 500mg pills, about 6-10g a day. Enemas should be done after you had a BM.
You probably have a tapeworm. Very common. Ascaris or other roundworms are very common too. Cleansing intensively is required for at least 1 year. Be sure to help your liver and your detox system. Toxins are dangerous. You can use all mentioned herbs and or meds. I have found a combination to be the most effective but an all natural protocol works too, if you dont have them all over your body. Keep cleansing daily for a year without mercy. These things are in abundance and very stubborn.
