Alyssa,
I don't mind at all. I'm happy to share any information I have that could prevent someone from harming themselves.
WARNING: I'm going to have to be graphic.
Super Dieter's Tea (Super D's Tea in Canada -- same product) is a natural laxative. It works the same way as ExLax and other drugstore laxatives. Essentially, what it does is to prevent your large intestine from re-absorbing water before you void your bowels. You end up losing a lot of water that would normally be retained.
So...for the most part, the weight you lose is water.
What I was doing was to brew the tea for 10 or 15 minutes rather than the recommended 1 to 3 minutes. The potency of the tea increases exponentially. The effects of a 10-minute cup are about 100 times stronger than the effects of a 2-minute cup.
The result was hours of explosive diarrhea that lasted for hours, sometimes for days. There were times when I literally could not get up off the toilet, because another wave would strike. I became so dehydrated during these bouts that I would get the shakes and sweats, terrible dizziness, and sometimes fainting. My body was attempting to purge all waste and as much water as possible. I had terrible cramps and was sick for a few days afterward. If I tried to eat or drink anything during this time, it would bring on another bout of diarrhea, shaking, nausea, terrible cramps, etc. So...in addition to the dehydration and other issues, I was also starving, because I couldn't eat anything while the tea was still in my system.
I had a significant electrolyte imbalance because of the dehydration, which can cause heart attacks. This is what Karen Carpenter died of.
The combination of the Super Dieter's Tea and other purging that I did (Ex-Lax, self-induced vomiting) caused acid reflux, stomach ulcers, and damage to my stomach lining. I haven't purged since I was 22, but some of the problems, particularly the acid reflux, persist to this day.
I suspect that a lot of the issues I dealt with were more to do with overall bad choices, rather than just the Super Dieter's Tea, but I know that other people have also had health problems from taking Senna in whatever form, and I just wanted to ensure that if you're using it you're being careful.
All the best, and please let me know if you need further detail.
