Fish oil, castor oil, prunes, herbs and probiotics are all effective home remedies for constipation, according to Everyday Health. Eating high-fiber foods and drinking plenty of water also help, as indicated by Best Health.
Fish oil and castor oil work quickly but cause gas or diarrhea in some people, notes Everyday Health. Dietitians recommend including 20 to 35 grams of fiber in one's daily diet from fruits, whole grains and vegetables. Figs, prunes and dried beans are other examples of helpful high-fiber foods.
Senna tincture and cascara sagrada are effective herbal remedies but are best used in moderation, according to Best Health. Dandelion tea is a mild herbal laxative.
