The water from steamed asparagus and asparagus stalks is diuretic. In the past, Dr. S. J. Jefferson of England prescribed an asparagus tincture to be used in half teaspoon doses along with other herbal diuretics. To make this tincture: Express the juice from five pounds of fresh asparagus. Simmer it until it reduces to a pint. Strain it and add to a pint of ninety proof spirit. Instead of fresh stalks, five ounces of dried tops of asparagus may be used to prepare the tincture.
