In Endotoxin with the Herb Doctors Ray says the following

In 1954, before Budwig had started writing about cancer, a Mexican professor had an article in Prevention magazine advocating—I think it was—a cup of linseed oil per day, as a purge, in the tradition of getting the intestine as clean as possible. And when you drink that much of a highly unsaturated oil, the unsaturated fatty acids are converted to prostaglandins and cause intense contraction and secretion of the intestine. So it's a very quick thorough kind of laxative.

To which article is Ray referring, and what is the name of the Mexican professor?
