There are many remedies for constipation but if you are suffering from long-term chronic constipation then the scope of those remedies does not cover long-term constipation. I do not know if I am allowed to share this but I was able to cure my chronic constipation through a certain remedy from a book "The Theory of Anti-aging and Healing through food heirarchy". The remedy requires the following ingredients. 1. milk 250-350ml (lukewarm) 2.1-3 tablespoons of extra-virgin olive oil 3. 2-3 tablesppoons of psyllium husk 4. Nigella sativa seeds (one pinch) 5. Honey 1-2 tablespoons. Make a smoothie and drink empty stomach first thing in the morning. The book is available on amazon, check it out if you like. The diet constraints that the author puts are impossible for a normal person to follow but their remedies are more than effective.
