GLYCERINUM. 285 



2. ACTION IN THE BLOOD, SPECIFIC ACTION AND USES. 



Olive oil enters the blood from the lacteals or lymphatics, 

 and may be traced in it if given in excess. Thence it enters 

 all the cells of the body, especially those of the connective 

 tissues, the amount varying with a number of circumstances. 

 Here it is fully oxydised into carbonic acid and water, and 

 constitutes one of the kinds of food, increasing the amount 

 of fat in the tissues, furnishing force, and thus saving the 

 waste of nitrogenous tissue and the necessity of consuming 

 quantities of nitrogenous food, but unable of itself to support 

 life. . 



Oils and fats are used in many forms (olive and other 

 vegetable oils, butter, cream, cod-liver oil, etc.), in wasting 

 diseases, such as scrofula and phthisis, as is fully discussed 

 under Oleum Morrhuee, page 379. Olive oil is rarely used in 

 this country, but may be taken by some patients, in the form of 

 sardine oil, when cod-liver oil is rejected. 



3. REMOTE LOCAL ACTION. 



Oils are excreted as carbonic acid and water, but excess 

 will appear unchanged in the urine. It is not a special renal 

 irritant like linseed oil.
