Nicholas Culpeper was a man who lived a long time ago, in the 1600s. He was a very important person because he knew a lot about plants and how they could help people feel better when they were sick.
When people got sick back then, they didn't have doctors like we do now. They had to rely on natural remedies that they could make from plants. That's where Culpeper came in. He was like a recipe book for natural medicines.
Culpeper wrote a big book that had lots of information about plants and how they could be used to help people feel better. He even wrote it in a way that regular people could understand, instead of using big, fancy words that only smart people knew.
Because his book was written for regular people, it became really popular. People started using it to make their own medicines and heal themselves.
Even though Culpeper lived a really long time ago, people still use his book and his ideas today. He taught everyone that plants can be really powerful and that we can take care of ourselves using things that grow from the earth.
