Hello! Ma Ren Lun Bowel Pill is a holistic adjustment for dry or irregular bowel movements caused by insufficient lung qi, slow bowel movement or lack of fluid in the large intestine.

Senna does not differentiate between the original cause of dry or poor stools, but only prompts the bowels to defecate. If the dryness or irregularity of stools is caused by a deficiency of qi it will hurt the qi even more. If the dryness or unavailability of stool is caused by insufficient fluid, the fluid will be discharged with the diarrhea.

So the side effects of Senna are greater than those of Ma Ren Lun Bowel Pills.
