For constipation. take Senna. Senna is a very safe natural plant product with a wide dosage range. Start by taking 2 tablets at bedtime, if you do not have a comfortable bowel movement (BM) the next day, take 4 tablets the next night. You can continue to increase the dose by 2 tablets every night until it works. It is safe and effective to continue taking the dose that works every night.
