How is apple cider vinegar, lemon juice and honey to relieve constipation?

Poor choice: Occasional constipation responds best to a real laxative such as milk of magnesia (magnesium hydroxide). Frequent constipation should prompt a check for thyroid disease and porphyria; if it's new, a check for colon cancer is of course indicated. If no medical cause is found, get some good advice on diet and drinking enough water. Best wishes.
