There are many ways of taking castor oil. Heat the glass or spoon, put in some orange or lemon juice, then the oil, then more juice. Open the mouth wide and put the oil far back. Have more juice at hand to swallow immediately after. Chilling the mouth by holding a piece of ice in it for a few minutes also helps to disguise the taste. A couple of tablespoonfuls of lemon or orange juice with a quarter of a teaspoonful of soda mixed thoroughly with the oil will make it effervesce so that it is not unpleasant to take. If the dose is vomited, wait a little while, then give another. Do not give directly before nor directly after a meal. _Olive oil_ is often taken in doses of one or two teaspoonfuls after meals to regulate the bowels or to help people gain weight or when the appetite is small. It is also used to rub into the skin of under-nourished babies and to rub sick people, especially if the skin is very dry. After rubbing with oil always wipe the skin with a towel. _Vaseline_ is used to grease sore and chafed parts. A little may be inserted into the nostrils for a cold. Camphorated vaseline is especially good for this. In case of an irritating cough that keeps a child from sleeping, a little plain pure vaseline may be put in the mouth, and it will be found very soothing. Vaseline is also used to grease such utensils as nozzles and to put on the parts to which poultices or fomentations are to be applied. _Soda_ may be used for burns (moisten and apply as a paste), as a gargle (one teaspoonful to a pint of water), as an enema (the same proportion), for colds (a teaspoonful in a quart of water to be taken internally in the course of each day), and in bilious attacks, water with this amount of soda may be given. Also to get a person to vomit, in which case the water should be slightly warm. _Salt_ may be used as a gargle in the same way as soda, and even mixed with soda, also for enemas. Coarse salt, when heated and put into bags, may be used when there is no hot water bag. _Lime water_ is used in mixing the baby's milk and is put in the milk for sick people when they cannot take full strength milk. The usual proportion is two tablespoons of lime water to a half glass of milk, which makes about 1 part of lime water to 3 parts of milk. _Alcohol_ may be used to disinfect the more delicate utensils as the thermometer. _Most alcohol now obtainable is wood alcohol or denaturated; that is, mixed with powerful poisons, so that it should never touch the mouth._ Never place a bottle of alcohol near a flame. If it is ever necessary to use an alcohol lamp, use the solid alcohol. It is much safer. _Camphorated oil_ is often used to rub the chest and neck with in case of colds. It should be warmed and rubbed in thoroughly. Protect the bedclothes and the patient's clothes with towels. After rubbing, wipe and cover the part with a flannel, to prevent chill.
