The Doctors View Of Sterculia

A laxative that I am particularly fond of as it doesn't cause the wind and bloating symptoms that other laxatives often cause due to fermentation in the bowel.

It bulks up the stool which increases bowel transit of your stools.

I look forward to reading your posts about this drug too.
