I got curious about the fasting tea and did some research. It does not contain Senna. Most of the herbs I recognized are good for cleansing various organs like the kidneys and liver. Now I remember it was the licorice root that kept me from buying the product. I was afraid it might affect my blood pressure. Anyway, this sounds like a good product. I started to edit out my original post, but thought I'd let it stand because my warning about the overuse of Senna is very real. I used a laxative tea everyday while doing several Master Cleanse fasts and it really messed me up.
