The number one cure is illustrated in this video. Consult your doctor first and then give it a go above the commercial drug he or she will prescribe. Consulting your doctor will hopefully give you a heads up, if there is something more sinister going on with your constipation.
Number two cure is a spoon full of Extra Virgin Olive Oil.
Number three cure is good old castor oil.
Number four cure is sparking apple juice.
Number five cure is celery. (Check if you get an allergic reaction before consuming)
Hope this helps.
