I think the book can be of interest if you want to learn about how to heal using magic. There's just few references to German folklore and German traditional healers.
I don't agree with the writer about the common tradition of Europe as there're different cultures and influences.
On a general level a nice read with some good idea and advices.
Recommended to whoever wants to read about healing using magic.
