I knew about pennyroyal as a contraceptive, but the others I didn't.
It is very possible that Paul's admonition against sorcery includes the practice of contraception, since in those times it was intimately associated with witchcraft. From the earliest times contraception was indicated against in Christian writings. As cameo-d's quotes say, contraception was a common practice in ancient times. But so was abortion and infanticide. That these things took place does not mean that Christians were encouraged to practice them, quite the opposite.
