I am also interested in this subject. I asked a nutritionist about it and she said she didn’t have much information but had heard of some success with using CBD for IBS. She did email me an article about it but I don’t know if I still have it. Her suggestion was to try it if I wanted to but to buy it from a source that is reliable and has dosage information. I never have. I tried a topical CBD ointment that my husband bought from a place that his friend buys from for my arthritis. It didn’t help at all. If I were you I would start by googling the subject.
