Hi Michele, all of the references for the courses are at the end of the notes. We don’t have a complete list of the therapeutic uses for Lavandin however, I’ve provided some resources below!
Google Scholar Search shows studies about Lavandin and anxiety, cancer cells, anti-micbrobial effects, etc. You can check out the individual studies here.
Much of Peter’s information comes from the books Aromatica (Volume 1 and 2) by Peter Holmes. Google books has a solid sample of Volume 2 you can see here.
I hope this helps! If anyone else has aromatic medicine resources to share here, please do.
