13. Giving Anesthesia
Anesthesia has been quite popular for thousands of years. You can trace the first versions of it as far back as Mesopotamia in 3400 BC. Then they likely used some powerful herbal remedies available to them at that point.
Once the Sumerians found poppy, this became THE anesthesia people used for hundreds of years. Ancient Egyptians stepped it up a notch and used some contents of the mandrake fruit. The Chinese and others eventually used it too. The Ancient Greeks probably developed it the most, considering the name itself is Greek in origin and translates to “without sensation.”
