Action And Therapeutics Of Cinnamon

Oil of cinnamon has the same action as other aromatic volatile oils, and is therefore stomachic and carminative. Cinnamon bark in addition has, in virtue of its tannic acid, some astringent action, and is consequently a common flavoring vehicle for astringent stomachic powders and mixtures, except such as contain iron. Finely powdered cinnamon (60 to 90 gr. 4, to 6. gm. ), is given night and morning in acute dysentery.
