branchandroot: cherries (cherries)
Just because this tends to tick me off, and it matters for the Naruto-verse.

So. Before the form of hormonal contraception currently known as the Pill, there were a bunch of herbal, chemical, and mechanical options for contraception. They fall into three general categories: barriers, measures that make the vagina and uterus inhospitable to sperm and thus prevent conception, and measures that make the uterus resistant to implanting and thus prevent gestation. (Yes, the morning-after pill is not a new idea; it is, in fact, a really, really old one.)

There is also the good old fallback of lactation, since lactation suppresses the menstrual cycle. But that only works when there's already a kid. So if you're a writer and thinking about "how to get my characters birth control", well that's more toward the family-planning end of things.

The thing is, every single one of the pre-modern methods are limited use approaches. They are used just before or after coitus. They may, in the case of something like pennyroyal, be used regularly once a month to ensure menstruation, but only for a few days. Half these options are "make a paste of these two or three things and dab it inside before you go for it". The other half tend strongly toward "take X much of this substance in the morning". (In a few of the second case, one also prays that it's enough to kill a blastocyst without killing oneself; it's really amazing how many places thought ingesting mercury for one purpose or other was a good idea.)

You wouldn't think this needs to be said, but apparently it does for some writers: this is the exact opposite of the Pill. There is no pre-modern form of birth control I have ever come across that is taken daily. That is an approach used with a medication whose effectiveness relies on constantly adding small doses of hormones which are not being natively produced. There is no herbal Pill, okay?

Of course, this leaves me with the question of what ninjas are using. )
