How to get rid of toxins and cleanse the colon?

No such toxins, but: Each person with constipation needs to be sure there is no other disease causing it. If constipation is just due to slow movement of the food and poop through the gut, then the things to try are vegetables, water, prune juice, prunes, fiber+water, Miralax, (polyethylene glycol) Senokot or other senna, milk of magnesia, other laxatives... A doctor can evaluate and prescribe helpful meds too. Exercise also helps.

Good & bad ways: I'M ALL FOR IT IF by "cleanse" you mean adopting a healthy lifestyle with routine exercise, cutting out tobacco, reducing alcohol & sugary drinks, minimizing highly processed foods & fats, & adding in lean proteins, whole fruits, vegetables, & nuts. DON'T DO IT IF instead you mean taking some fad diet, enema, colonic, or purgative to lose weight or supposedly rid your body of unspecified "toxins."
