Dropsy.--This trouble is rather a symptom than a disease. It rises from accumulation of watery waste in the body, owing to improper action of the skin, lungs, or kidneys, and sometimes follows scarlet or other fevers and lung affections. By far the greatest danger in such cases arises from fashionable medicines. It is of the last importance that nothing should be given to lessen life by injuring already weakened vital action. It is when this is done by metallic preparations that such cases become very grave and even hopeless. There is a prominent error in connection with all dropsical tendencies, which should be removed. That is the idea that the "water" which collects in such swellings is similar to good drinking water, and that giving the thirsty patient water to drink is increasing his illness. The so-called "water" which swells the face, or the feet, or any other part of the body, in dropsy, is used-up matter such as is, in good health, removed (imperceptibly, in greatest measure) by the organs fitted for that purpose. Water, especially if given about blood heat, is at once used for most important vital purposes. This hot fresh water mingling with the poisonous "water" of dropsy dilutes it--renders it not only so much less injurious, but tends powerfully to its removal. The thirst of the patient is in perfect harmony with this truth, as all natural symptoms are ever in harmony with nature. If there are convulsive attacks, they are the result of used-up matter returning into the circulation, and reaching even the brain and central parts of the nervous system. The cure is gained when the defective organs are brought to act well. It is shortsighted action to deal with the kidneys alone in this trouble. They often fail because they are overloaded through the failure of lungs and skin to do their part. First, it is well to act on the lungs by gentle rubbing with hot olive oil between the shoulders and over all the back--done best in a warm room by the fire, or in bed. This may be continued for half-an-hour or more twice daily. The skin may be stimulated by a smart sponging with vinegar or weak acetic acid, and a rubbing all over with soap lather, and afterwards with hot olive oil. This lathering and rubbing to be done at another time from the first rubbing for the lungs. Then apply a large warm bran poultice to the lower part of the back behind the kidneys.
