In the clinic, after resolving constipation I am getting people with sluggish (every other day) bowel movements. I am assuming that the pattern is moving from Yang Ming excess closing to an excess Jue Yin closing pattern. Would this indicate a Ma Zi Ren Wan (YM+JY) formula or something more strongly Jue Yin related?

I suppose implied in the question is does the "pumping" action of the Jue Yin PC include a direct action on the LI and peristalsis?  

Thanks in advance.
