If you're referring to the commonly suggested Smooth Move brand of laxative tea, I'd say switch to a different tea for the Master Cleanse. That tea is based on the herb senna, which is a harsh laxative that is particularly harmful to the condition of your bowels with prolonged use. So to keep the toxins moving out of you during the Master Cleanse, I'd suggest chamomile tea (more info at ) and be sure to do the Master Cleanse's salt water flush first thing every morning. That will keep the toxins moving out without being as harmful to your bowels as a senna-based tea. Oh, and the chamomile tea is mild and pleasant. Gagging is highly unlikely.
