The most common symptoms for those with Yin deficiency include dry mouth, dry throat, insomnia with excessive dreaming, dry stools, irritability, tinnitus, and night sweats; men may also experience high libido but short duration, and nocturnal emissions. Symptoms of Yang deficiency include a cold body, lack of energy, loose stools, increased nighttime urination, and a cold lower abdomen; in men, this manifests as decreased libido, feeling powerless despite the desire, and insufficient firmness. If one suffers from both Yin and Yang deficiency, should they supplement Yang first or Yin first? It is recommended to nourish Yin first, and then warm the Yang on the basis of nourishing Yin—that is, to nurture Yang within Yin and seek Yin within Yang. For nourishing Yin, one can refer to Liuwei Dihuang Wan, which is commonly used to nourish the liver and kidneys, improve kidney Yin, and clear deficiency fire. Once the Yin fluids are gradually replenished, it can be paired with Guifu Lizhong Wan to supplement Yang. In this way, one can both nourish Yin and warmly supplement kidney Yang, truly achieving the dual replenishment of Yin and Yang.
