CBD oil may not only relieve constipation, but also work as a preventive supplement. When it comes to constipation, CBD oil can help stimulate the digestive system and help move stools through the intestines. It is made by extracting CBD, or cannabidiol, from the cannabis plant and then diluting it with a carrier oil, such as hemp seed oil or coconut oil.
