Ian Gordon asks:
I recently came across some material which obliquely referenced various native American herbs and plants which could be used as contraceptives. Apparently male anthropologists asked the men about population control and got nothing but shrugs in return. Female anthropologist asked the women and got the low down.
I was wondering whether anyone has any more information on this topic. It's not the first time I've stumbled across stuff like this. I recently read an article which claimed that an extract from the Neem Tree could render men temporarily sterile without diminishing libido.
The Navajos, who called the Ragleaf bahia herb twisted medicine, drank a tea of the roots boiled in water for thirty minutes for contraception purposes.
