Senega is an irritant to all mucous membranes 

 and is classed as a stimulating expectorant. 



Injected into the circulation senega disintegrates 

 the red corpuscles and stops the heart in diastole; 

 there are convulsions, followed by paralysis of the 

 respiratory center. Its irritating properties might 

 be dangerous were much of it absorbed; but little 

 is absorbed. Senega, in considerable dosage, is 

 diuretic, emetic, cathartic, and emmenagogue; but 

 it is too irritating to use in any but very moderate

 is deficient in subacute and chronic bronchitis, and 

 it is necessary to promote expectoration, senega is 

 one of the drugs of choice. It should not be ad- 

 ministered if gastro-enteric irritability exists. Senega 

 is commonly prescribed in combination with other 

 expectorants. 



The average dose of the fl. is 15 minims, of the
