Discussion on the prescription thinking of infertility based on "primarily sweet, with all four flavours harmonized" in Fu Qingzhu′s Obstetrics and Gynecology.

The combination of sourness, bitterness, sweetness, pungency, and saltness results in different effects. Through the analysis of the theory of combining five flavours in Fu Qingzhu′s Obstetrics and Gynecology, this article explores its application in formulation ideas and the characteristics of Chinese medication, summarized as " primarily sweet, with all four flavors harmonized". FU Qingzhu emphasizes the central role of sweet-flavour medicine in facilitating conception, while incorporating the other four flavours in synergy. For instance, sweet and pungent flavours can boost yang energy, eliminating chilliness and warming the uterus; sour and sweet flavours can nourish yin essence and protect the uterus; bitter and sweet flavours can tonify yin, supporting the kidneys and moistening the uterus; and pungent and salty flavours can eliminate stasis, regenerate blood, and enhance uterine functions. By flexibly utilizing the flavours and meridian affinity of traditional Chinese medicine, along with the theory of combining five flavours, it is possible to enhance drug compatibility, deepen the theoretical connotation of Chinese formulas, and regulate the uterus from both yin and yang aspects to facilitate conception. FU Qingzhu′s integration of multiple Chinese formulas into a single formula allows for comprehensive treatment. Clear differentiation of dosages within the formula highlights the primary and secondary relationships of traditional Chinese medicines. Additionally, the utilization of pharmaceutical processing techniques optimizes efficacy and regulates meridians and collaterals. This article explores FU Qingzhu′s application of the " pure and harmonious traditional Chinese medicines" theory. His prescription thinking enables the attainment of multi-level therapeutic effects, which greatly benefits the optimization of traditional Chinese medicine fertility assistance programs and increases pregnancy rates among infertility patients.
