For married women, this scheme is very helpful.
For unmarried women, this scheme is not useful.
These sentences are clear because we have a term unmarried. I face difficulty describing the same thing whilst talking about the herb that increases the breast milk (of course, in mothers) but then it does not mean that women who are not mothers cannot use it for the breast enlargement.
[Herb] increases the quantity of breast milk in mothers but non-mothers can also take the herb as it helps multiplying the breast tissues resulting in a natural breast enlargement.
I'm not talking about a woman with infertility. I just want to refer a woman who has no issue/child. To make you all understand, I have referred her to as a non-mother. I don't want to use unmarried as it does not serve the purpose.
I can write ... "breast milk in mothers but women in general can also take the herb..." but then it's paraphrasing. I need the term, if available.
