Oil of Argemone.—This fat oil, obtained by pressure from the seeds, is 
reported by Wittstein, but upon whose authority we are unable to ascertain. He 
describes it as, light yellow, still liquid at 5° (41° F.), of a slightly nauseous odor 
and raw taste, drying, dissolves in 5 to 6 times its volume of alcohol, and is easily 
saponified. 
PHYSIOLOGICAL ACTION.—This is as yet unknown, but certainly deserves 
prolonged experimentation.
