The pine-apple should be cut up and well pounded in a mortar. The juice must then be pressed out and strained through well-scalded muslin. The patient's mouth must be washed out with warm water. The juice may now be given with a silver teaspoon. It is possible that the patient may be quite unable to swallow any of it. If this be so, the juice will serve as a mouth and throat wash. It will gradually dissolve the membrane, and enable it to be scraped gently away with the spoon. The juice should be given, and the throat scraped as far down as the nurse can reach, as often as the patient can bear it. The time will come, sooner or later, when the juice is swallowed. No other food should be given. The nurse may have to work away for some hours before any juice is swallowed, but my friend assures me that if the scraping be done gently and skilfully, even children will bear it patiently. Only a silver or bone spoon should be used, and, needless to say, it must be well scalded in boiling water in the intervals of using. It is a remarkable fact that while pine-apple juice exercises this remarkable corrosive power upon diseased mucous, its effect upon the most delicate, healthy membrane is absolutely harmless. I have seen sweet pine-apple juice given to six-months-old babies as a supplement to the mother's milk, with excellent results. Dr. Hillier, writing in the _Herald of Health_ in 1897, says "Sliced pine-apples, laid in pure honey for a day or two, when used in moderation, will relieve the human being from chronic impaction of the bowels, reestablish peristaltic motion, and induce perfect digestion." "A slice of fresh pine-apple," writes Dr. Fernie, "is about as wise a thing as one can take by way of dessert after a substantial meal." This is because fresh pine-apple juice has been found to act upon animal food in very much the same way that the gastric juice acts within the stomach. But vegetarians should eat fresh fruit at the beginning of meals rather than at the end. The pine-apple is useful in all ordinary cases of sore-throat. One pine-apple of average size should yield half a pint of juice. Tinned or cooked pine-apple is useless for curative purposes. _Pine Kernel._ Pine kernels are recommended to those who find other nuts difficult to digest. They are the most easily digested of all the nuts. They are often used for cooking in the place of suet, being very oily. _Plum, Prune._ The disfavour with which "stone fruits," especially plums, are generally regarded owes its being to the fact that they are too often eaten when unripe. When ripe, they are as wholesome as any other fruit. Unripe they provoke choleraic diarrhoea.
