 Parts used Fruit, rind, juice. 



Action Tonic, refrigerant, antiscorbutic. The juice 

 may be freely used as such, or in syrup form as a 

 refreshing drink in all febrile diseases. It is a popular 

 remedy in coughs and colds. The rind is mostly 

 employed for flavouring purposes both in household

Distinctive character This well-known fruit occurs 

 in several varieties, which differ in thickness of rind, and 

 consequent percentage of juice. Those with moderately 

 thin peel, and of medium size, about 2^-3 inches long 

 and 2 inches in diameter, are the best, and the Messina 

 lemons have the finest flavour. Coarser lemons from 

 Malaga arrive in September and October. These have 

 thick skins and numerous seeds, and less juice. A 

 medium-sized lemon yields about two ounces of juice 

 containing 40-46 grains of citric acid per ounce, or 

 about 9^ per cent.
