>I wouldn't expect mint-family herbs to have much hormone modulating effect at all
Mints are closely related to pennyroyal (Mentha pulegium), which was traditionally (and dangerously because of toxicity) used as an abortifacient. Its mechanism of action is still unknown, so hormone modulating effects seem plausible to me.
By "mints" I meant the family lamiaceae, so pretty broadly which contains sages, rosemaries, basils, teak, verbena, and in hindsight of course contains examples like this which straddle medicine (depending on dosage and circumstances -- I'm not advocating it be used as such) and poison. Even if just restricting to the genus mentha apparently. Anyway good call
Sit and drink pennyroyal tea, I’m anemic royalty.
Also used as lactation reducing herb.
