Herbal medicine in the Jewish Renaissance rare medical handbook The Guide to the Tree of Life (Sejfer derech ejc ha-chajim)

The only known copy of Sejfer derech ejc ha-chajim, an anonymous old print, is stored in the Austrian National Library in Vienna. It was written in the Yiddish Ashkenazi language and printed in 1613. The author, a Jewish physician, resided or lived in the Polish-Lithuanian Commonwealth. This rare book, although it was printed over 400 years ago, has not yet been systematically assessed in the ethnomedical context of those times.
