Li Shaojun gave him two sets of medicine and prescriptions, instructing him to use herbs grown in the Wusi year, vegetable oil produced locally, radix ophiopogonis, and animal fat. In autumn, he should use the first wilting roots and in spring, the sap from various flowers. In the first ten days of December, he should combine the above-mentioned herbs and simmer them in a copper vessel. He should ask a child who was meticulously clean to observe the heat and to make pills the size of chicken eggs from the paste that was produced. Three pills constituted one course of treatment.
