I am by far no expert in NBE, but I would assume, as with anything taken for a period of time, a break in between regimens would make the herb just as effective as if you had never taken it. I guess it all depends on the dosage, and the amount of time you took it.

Also, if you are trying to grow your bum, and it's the same herbs that help grow breasts, you might as well just do both at the same time. I don't see how you could stop the herbs, if they wanted to target your breasts anyhow.
