Take the patient's morning urine and put the same into a bottle; then take a small piece of saffron, and tie it up in a fine piece of muslin, and put the same in the bottle amongst the said urine; and only desire the patient wholly to abstain from drinking either milk or malt liquor for one month. Proved a great number of times.
