1. Take the method of drinking silver for contraception.
Mercury can indeed be used for contraception, but mercury is highly toxic, so drinking a small amount may not kill people. More than 4,000 years ago, women in China added a small amount of mercury to tea or daily food for contraception, which is said to have a good effect. According to modern scientific research, a large dose of mercury can kill people, but a small dose can kill the fetus in the uterus.
Mercury can cause menstrual disorders, brain damage, renal failure and infertility in women.
2. Use toxic drugs such as arsenic for contraception.
In ancient China, prostitutes in brothels used some poisonous drugs in traditional Chinese medicine for contraception, as well as arsenic for contraception. Although large doses of these drugs can kill people, small doses of these drugs can kill the fetus in the uterus. Therefore, prostitutes who use contraception in this way are permanently and irreversibly infertile for life, and pimps often secretly drug them when they first start to be prostitutes.
3, lead water contraception while the iron is hot
The ancient Greeks believed that water while the iron was hot could also be used as a contraceptive. Although I don't know who invented this method, it is a fact that there is lead in hot water. During World War I, the proportion of women working in lead-containing factories was unusually high. Scientific research has found that striking iron can lead to nervous system diseases, renal failure, coma and even death.
4. Use animal excrement as a contraceptive.
The ancient Egyptians more than 3,000 years ago were able to create such outstanding works as pyramids and mummies, so it is not surprising to find a way to control fertility. It is said that the ancient Egyptians believed that crocodiles, elephants and other animals had mysterious powers, so animal droppings were also used as contraceptives. In fact, due to the high acidity of these animal droppings, they do have a certain spermicidal effect.
5. Take "cold medicine" for contraception
There was no 100% effective contraceptive method in ancient times. It is said that Wei Xiaobao is the product of contraceptive failure. In the past, many prostitutes were infertile for life after rehabilitation, that is, they were sterilized by drinking a soup that destroyed fertility for a long time. It is said that eating a contraceptive called "cold medicine", which also contains musk, will affect fertility, but not necessarily sterilization.
