Eating some Maple Syrup either on pancakes or by taking some maple syrup directly can sometimes help relieve constipation if you consume enough of the maple syrup.
You would likely need to consume at least half a bottle of maple syrup in one day for the maple syrup to have a laxative effect on you and get your bowels moving though.
Other ways that work even better at getting rid of constipation is drinking more water, drinking prune juice or drinking some apple juice and eating prunes.
If you eat enough prunes or drink enough prune juice you can get your bowels moving naturally because you'll usually start feeling bloating and stomach cramps when you eat prunes or drink enough prune juice and then you'll be running to the toilet.
If the natural ways of helping the constipation don't work fast enough then you might need to take some laxatives that you can buy over the counter.
