Castor Oil is a most valuable medicine, as it generally operates
quickly and mildly.
It is _used externally,_ combined with citron ointment, as a topical
application in common leprosy.
It is _used internally_ as an ordinary purgative for infants, as a
laxative for adults, and in diarrhoea and dysentery. In colic it is
very useful and safe; and also after delivery.
_Dose_ for _infants,_ from forty drops to two drachms; for _adults,_
from half an ounce to one and a half ounces.
