 oil were given in soluble elastic capsules, the patient 

 would take sufficient dosage to secure an effective 

 action. My patients would rarely tolerate over 5 

 minims of a 10 per cent, tincture, and these doses 

 are not effective. True oil of Ceylon cinnamon is 

 very expensive. 



As a flavor, cinnamon spirit and cinnamon water
