I didn't think your remark "really went wrong" or anything like that at all! I just didn't understand what you meant for sure, and I wanted to know what I was missing :)
I didn't know/realize that senna was that potent, but apparently it is recommended by others something to "keep a watch on" as far as the laxative properties and overusage. That's really good to know!
Your post has already really helped me to learn something (and I always want to know WHY everybody is doing whatever it is they're doing). Heavens only knows, the "majority" of doctors in this country don't seem to have any idea why they do things...they just do something because every other doctor does it :(
Thank again, hanna - it's always great to learn something new!
