Okay kiddo, have you ever heard of a charm before? It's like something magical that you say or do to keep bad things away. The Nine Herbs Charm is a special kind of charm that was used a long time ago in England by people who believed in magic.
The Nine Herbs Charm is made up of nine different plants that people thought had magical powers. Each plant was supposed to help with a different kind of problem. For example, one of the plants was supposed to help heal wounds, and another one was supposed to protect you from poison.
When people used the Nine Herbs Charm, they would say special words while they mixed the plants together. They might put the mixture on a wound, or they might sprinkle it around their house to keep bad spirits away.
Today, most people don't believe in magic anymore, so they don't use the Nine Herbs Charm. But some people still like to study it because it tells us a lot about what people used to believe a long time ago.
