In my opinion the safest and most natural home remedy for constipation is my power pudding recipe. It actually works great, you can take it everyday and never worry about getting dependent on drugs to relieve your constipation.
It only has three ingredients, apple sauce, prune juice and wheat bran. You can make a batch and eat a tablespoon everyday to keep yourself regular. You can find the recipes if you go to the button on the left that reads "Home Remedies" scroll to the middle of the page and look for the link that says "Constipation Relief".
