I did go 'cold turkey' on the caffeine. Maybe that is it? But I don't think there is any senna in the tea. The only brand I've used is Celestrial Seasonings and I don't recall that being in any of their products.

It may just be me... I have a lot of trouble in this area.

I've e-mailed the company to ask if any of their teas have a laxative effect. I hope they will respond soon!

Regards,
