What does CBD actually do?

So, I'm curious to know, what exactly does CBD do? I've heard it touted for a wide range of benefits, from reducing anxiety and inflammation to promoting better sleep. But is there any solid evidence to support these claims? I'm interested in learning more about the science behind CBD and how it interacts with our bodies. Is it SAFE to use? And what's the best way to consume it? I'm eager to get a clear understanding of this increasingly popular supplement.
