A branched plant, varying much in size. It is called in France, 

 Cranson officinal; in Germany, Loffelkraut. The Common 

 Scurvy-Grass when fresh has a peculiar smell, especially when 

 bruised, and a kind of acrid bitter taste, which it loses completely 

 by drying, but which it imparts by distillation to water or alco- 

 hol. It also furnishes an essential oil, with sulphuretted hydro- 

 gen, the smell of which is extremely pvingent. The fresh plant 

 is a gentle stimulant and diuretic, and is chiefly used for the cure 

 of sea scurvy. It may be eaten in substance, in any quantity, 

 like the water-cress, or the juice may be expressed from it, or it 

 may be infused in wine, beer or water, or its virtues may be ex- 

 tracted by distillation. The juice is recommended as a gargle in 

 scorbutic affections of the gums and mouth. The whole of this 

 section Cochlcar possess more or less of the above virtues. 

 When this plant is to be cultivated for use, sow the seeds in July, 

 in drills eight inches apart, and when the plants are up thin them 

 to six inches apart ; those thinned out may be planted into new 

 beds. In the following spring the succulent leaves will be fit 

 for use.
