A Capital Remedy Against the Plague.
Take a vial or another kind of glass vessel, and fill it one third with fine molasses, and the next third with Aqua Vitae, and the final third with the urine of a male baby who is clean and in good health. Combine these together well and give one glass of this to the patient to drink upon awakening each morning, for three days. This has been proven in the city of Venice, in the year 1504.

These Electric Insoles contain the pure polished metals arranged in such a manner that a mild pleasant current is produced along the soles of the feet, which stimulates the blood and keeps it circulating constantly. They are worn with good results for cold feet, and to keep the feet dry.

The Quack Doctor's blog has a post all about an old-time invalid food called Valentine's Meat Juice. However, eating was apparently not the only thing it was used for:
An enema described in The Philadelphia Medical Journal in 1900 comprised one egg, one tablespoon of Valentine’s Meat-Juice, 4oz sterilised milk, ½oz. brandy, ½ tsp. salt, and 5oz of sterilised water. Two ounces of this mixture was to be administered every two hours ‘as high up in the large bowel as possible.’
The benefits to be had from this process are unclear.
