In the same way that the story of Canute now means something very different to its origins, linguistically we may well be at the same stage for the general understanding of "Mother's Ruin".
I'd agree with a PP that Hogarth's Gin Line is a popular depiction of gin as the opium of the people and, along with other social forces, prompted the Gin Act. Associated with gin, the critical force behind Mother's Ruin was women's increased access to alcohol and the impact of widespread addiction.
I'm unsure if it's ever been clear that gin is an abortifacient rather than the savin within any juniper used in the flavouring of it.
MN embrace
but I have never seen support here for consumption to Hogarthian Mother's Ruin levels. I'd think suggestions that the name should be abandoned for reasons related to historical sensitivity and cleaving to those origins are very much a matter of personal choice.
