and head cabbage / are in Germany in ordinary kitchens/
especially for the manual laborers/ and the common
man / who [have] the largest hardest burden /and take it for daily
food / and grease their hungry stomachs / and as

coarse thick melancholy blood / it ruins the face...
It goes on to tell that it creates fantastical dreams.
