Senega
SENEGA, the dried root of the Polygala Senega, which is official in the British and United States pharmacopoeias. Senega contains an active principle, saponin. Senega is used chiefly as a stimulating expectorant in chronic bronchitis. It is occasionally used as a diuretic in renal dropsy. It is a cardiac depressant, and is contra-indicated in diseased conditions of the heart. It has a tendency to upset the digestion, and is therefore only used in combination with other drugs in what are termed expectorant mixtures.
