I take cascara sagrada a few times a week only, at night with the psyllium alone or with benonite with it. Depending on how long ago I ate as it should be an hour or two away from food, a real hassle to keep up with regarding the benonite. So sometimes I just do psyllium alone.
Anyway, psyllium is a laxative. Think of it like this, psyllium is the scrub brush and cascara sagrada is the pusher. Something like this. It has herbs for the work too which are good for our colon. I just dont use it too often, like not every day. But if you have those dead guys in there, you dont want them to stay there.
