Liu Wei Di Huang Wan and Jin Kui Kidney Qi Wan can be taken at the same time, both of which can be beneficial to the kidneys. Liu Wei Di Huang Wan focuses on replenishing kidney yin, while Jin Kui Kidney Qi Wan focuses on tonifying kidney yang. Both can be used as an aid to adjust weakness of the waist and knees, weakness, lack of energy, impotence, premature ejaculation, seminal emission, spermatorrhea, and female infertility caused by weakness of the kidneys. The application process must be taken orally during the daytime, as nighttime tends to cause patients to develop cold. Reduce the amount of each of Liu Wei Di Huang Wan and Jin Kui Kidney Qi Wan by half during the application process to prevent the discomfort associated with too much yin nourishing medicine and induce excess dampness in the body, diarrhea, etc. Because the ingredients of Liu Wei Di Huang Wan and Jin Kui Kidney Qi Wan are mostly the same, except that Jin Kui Kidney Qi Wan has more cinnamon and sophora than Liu Wei Di Huang Wan, so care must be taken to reduce the amount by half in the process of using the medicine.
