One thing we’ve lost, in the modern day, is the notion of poisoning as a particularly feminine pastime. That was a pretty firm association for a while, that where men might get impulsively, physically rough women’s violence was calculated and chemical, poisoning abusive or just unsatisfactory husbands, or parents who refused assent to marry a lover, or in-laws to “hurry the inheritance”.

You’d see that association invoked in things like Arsenic and Old Lace, but the last pop culture surfacing I can think of is the Dixie Chicks’ 1999 “Goodbye Earl”. (Maaaaybe Gillian “Gone Girl” Flynn’s ‘06 debut novel Sharp Objects but that’s reaching.)

Probably has a lot to do with forensic advances ruining the party, you still see the dynamic in suicide, with women favoring overdose and men trauma.

(probably a lot to do with the decline of from-scratch food prep, too)
