238 SPECIFICS FOR THE ALIMENTARY TRACT 



b. FIXED OILS AND THEIR PRODUCTS (SOAP AND 



GLYCERIN) 



As stated previously neutral fats and saponified oils like butter 

 and olive oil pass through the stomach unchanged, but are saponified 

 more or less completely in the small intestine, and the resulting soaps 

 may be sufficiently irritating to the intestinal mucous membrane to 

 cause increased peristalsis, and, with an excess of the fat or oil, act 

 as mild laxatives.

OLEUM LINI

 A fixed oil expressed from linseed. It contains the glyeerides

 oil is commercially termed " raw oil," that is, the oil just as it comes 

 from the press. For painting purposes the raw oil is cooked with 

 litharge, thereby enhancing its " drying " properties. This oil is 

 then termed " boiled oil " and should not be used in medicine since 

 it is very toxic.
