I guess the lax tea is natural because it is plant based. I find it harsher than the SWF (Salt-Water-Flush) and would do that instead of the lax tea if I was doing what you are planning on doing. Maybe not every morning, but every other depending on how things are 'moving.'
Eating raw vegies and maybe some whole grains for dinner, you might find that keeps the bowels happy enough without doing either the tea or SWF. Best wishes!
