My thought is that it is natural. The the herbs we choose to take are not synthetic creations.

The herbs themselves are not synthetic. But unless you took whole herb stalks and stems, and brewed a tea from them (fenugreek tea is awesome, BTW), then more likely than not there was some kind of chemical treatment done to them.

Most of the ways don't involve Chemicals.

all the same I personally Currently Classify NBE as Breast Growth/Enhancement Via steering the Body's Chemical Balance with Substitute/Bioidentical chemicals (of Chemicals Naturally occurring within the body) to the balance that is needed to go in the direction desired.

(Kindof like steering a car)
