When the deficiency of kidney yang (lack of yang qi in the kidneys) is mainly manifested by symptoms such as fear of cold, lumbar and knee soreness and weakness (a feeling of soreness and weakness in the lumbar and knee areas), impotence and spermatorrhea, the clinic can be adjusted by taking medicines to warm and tonify the kidney yang (warm and replenish the yang qi of the kidneys), for example, Gui Su Di Huang Wan (桂附地黄丸). Gui Fu Di Huang Wan is composed of cinnamon, epimedium, radix Rehmanniae Praeparata, Chinese yam, moutan skin, poria, Cornu Cervi Pantotrichum and Ze Xie, which has the effect of warming and tonifying kidney yang (warming and replenishing the yang qi of the kidneys). It can be used in the treatment of kidney yang deficiency (lack of yang qi in the kidneys) resulting in lumbar and knee soreness (a feeling of soreness and weakness in the lumbar and knee areas), dysuria (unsmooth urination) and other conditions. Avoid spicy and stimulating food while taking this medicine, and patients who are allergic to this medicine should not use it. 2. Liver yin and yang, so the deficiency of liver yang is manifested by the malfunction of liver, which is mainly manifested by abnormal mood, abnormal menstruation in women, bitter taste in the mouth, distension and pain in both sides of the mouth, etc. Since liver yin and yang, the clinic doesn’t directly tonify the liver yang, but indirectly tonifies liver yang by nourishing water and wood, i.e., by warming and tonifying the kidney yang, the water generates wood, and then it will be able to achieve the effect of tonifying the liver yang.
