I am not one for herbs as a rule, but I love history, so I did a bit of research on the humble Bay leaf. In Roman times they had a lovely and wonderful Idea. They took all the educated women who were single and made them vestal virgins, Here the learned many things. How to heal via medicine and herb, how to practice law, poetry, art and music, and lastly how to be a political wife. They used bay leaf as a pain killer, hand fulls of the leaves were dumped onto low burning fires, within the houses of healing. The fumes from this when breathed in took away pain and gave rest. So I had a go myself, I ground up a bay leaf until it was powdery, and put some in with my hand rolled smoke. All I will say is, it works on head aches in seconds, back pain in about a minute, and MS pain in seconds. It is the only one I use, Oh it smells like weed when it burns, and depending on how fine you grind it, you get quite a high as well.
