Take *Jitou* (Euryale ferox seed), remove the outer skin, crush the fruit together with the shell until fragmented, dry it in the sun, and grind it into powder. Then take *Tangyingzi* (a type of plant fruit), remove the external thorns and internal seeds, wash clean, and crush. Place it in a steamer and steam until cooked. Use the water from steaming to rinse the dregs three times, collect the *Tangying* juice, and pour it into a silver pot. Slowly boil over low heat until it becomes a thin paste. Use this paste to mix with the *Jitou* powder and form pills the size of *Wutong* (Chinese parasol tree) seeds. Take 50 pills each time, administered with salted water. Long-term use consolidates the True Yuan (original Qi) and enhances complexion luster. Wu Yinzhang from Kuocang took this medicine for a long time and achieved remarkable results. (This medicine has a slightly constipating effect; if constipation occurs, it can be relieved with powder of *Cheqianzi* [Plantago seed].)
