In the seventh episode of A Dream of Red Mansions, Baochai got a disease, which was heat poison brought from the womb, and she had symptoms such as wheezing when she committed it. A monk told Baochai a "sea fairy prescription". This medicine is called "Lengxiang Pill". Since Baochai took it, it has also had an effect. According to the book, Lengxiang Pills are made by grinding white peony flowers, white lotus flowers, white hibiscus flowers and Bai Meihua stamens into twelve taels of powder, blending them with the rain at twelve taels, dew of the White Dew, seasonal frost of the first frost and seasonal snow of that year, adding honey and sugar to make Jackie Chan Eye Pills, filling them into utensils and burying them under the flower roots. At the onset, take one pill with Cortex Phellodendri decoction 12. There is no record of "Lengxiang Pill" in medical books. Even though the author invented the pen, its prescription is quite intriguing.
