bubble_chart Preparation and Dosage

Mix the two medicines evenly, use a bamboo knife to cut the pig liver into two pieces, spread the medicine powder on one piece, cover it with the other piece, and tie it tightly with hemp string to prevent the medicine powder from leaking out. Use 500 ml of rice-washed water in a clay pot, add the liver, and boil until reduced to 200 ml. Consume both the liver and the medicinal liquid before sleep.
