Efficacy and Functions of Aifu Nuangong Wan

Ai Fu Nuan Gong Wan is a traditional Chinese patent medicine whose general therapeutic effects include warming the meridians and dispelling cold, regulating Qi and nourishing blood, warming the uterus and relieving pain, regulating menstruation and stopping excessive vaginal discharge, and supporting conception and stabilizing pregnancy.

1. Warming the Meridians and Dispelling Cold

The ingredients in Ai Fu Nuan Gong Wan—such as Artemisia leaf (Ai Ye) and Cyperus rhizome (Xiang Fu)—possess properties that warm the meridians and expel cold. These herbs help eliminate cold pathogens from the uterus, thereby alleviating menstrual disorders and dysmenorrhea caused by cold-induced blood stasis. They promote smooth menstrual flow and relieve abdominal pain, chills, and cold intolerance during menstruation.

2. Regulating Qi and Nourishing Blood

Cyperus rhizome (Xiang Fu) in the formula regulates Qi and resolves stagnation; Artemisia leaf (Ai Ye) warms the meridians and stops bleeding; Angelica root (Dang Gui) and Szechuan Lovage root (Chuan Xiong) nourish and invigorate the blood. Together, these herbs synergistically regulate Qi and nourish blood, effectively correcting imbalances in Qi and blood. This ensures abundant and smoothly circulating Qi and blood, making the formula particularly beneficial for treating scanty, pale menstrual flow resulting from Qi and blood deficiency.

3. Warming the Uterus and Relieving Pain

A primary function of this formula is to warm the uterus, thereby significantly improving uterine cold deficiency. It effectively relieves cold-type abdominal pain and a sensation of heaviness or distension associated with “cold uterus.” By warming the uterus and harmonizing Qi and blood, it reduces pain and alleviates abdominal discomfort experienced before, during, or after menstruation.

4. Regulating Menstruation and Stopping Excessive Vaginal Discharge

Ai Fu Nuan Gong Wan effectively regulates irregular menstrual cycles and abnormal menstrual volume (either excessive or scanty). Additionally, it treats leukorrhea—characterized by profuse, thin, watery discharge—caused by uterine cold deficiency. By warming the uterus and regulating Qi and blood, it restores normal menstrual patterns and normalizes the quantity, color, and consistency of vaginal discharge.

5. Supporting Conception and Stabilizing Pregnancy

For women experiencing infertility due to uterine cold deficiency, Ai Fu Nuan Gong Wan may support conception. By warming the uterus and improving the intrauterine environment, it enhances conditions favorable for blastocyst implantation and embryonic development. Its actions of regulating Qi and nourishing blood further contribute to increasing the likelihood of conception.
