The pineapple is another of the universal favorites and deservedly. Its
delightful flavor is unequaled and the fresh juice contains bromelin,
a remarkably active principle which aids digestion both in the stomach
and in the intestinal tract. A slice or two of pineapple taken at the
close of a meal gives a marked laxative effect. The use of pineapple
in diphtheria is well known. I knew a very successful physician in one
of our large cities who always had quantities of pineapple canned each
year for use in diphtheria cases. The digestive ferment is not quite so
active in the cooked fruit as in the uncooked.
