Is "Castor Oil" made from that plant, as the name implies?


Yes. It is pressed from the seeds.




I ask, because during WW I, many aircraft engines, "rotary engines,"
were lubricated with Castor Oil, which was pumped overboard rather
than recirculated. Pilots could not avoid ingesting the stuff.

Castrol brand motor oil does, or at least at one time did, have castor
oil in it

The Italian Fascists would dose their opponents with castor oil to
give them explosive diarrhea and then march them through the streets
to
humiliate them.
